6:30pm, Showers over S. & central Kerala , S-W coastal Maharastra and S.central & N-E Andhra ..
October 3-7 and October 7-11, when more than one circulation is shown wending their way from the Bay into the South-East Coast of India.
ECMWF sees an eventful week unfolding with a reasonably big ‘weather system' shaping up in the Bay...
Bay is also expected to throw up a LOW system, to set up a trans-peninsular trough from October 6 ...

Arabian Sea ‘low' sustains peninsular rains

The persisting cyclonic circulation over Lakshadweep has tossed up a low-pressure area with associated southeasterlies, helping sustain rainfall over South Peninsula.
A ‘low' over Lakshadweep should normally direct a barrage of southwesterly winds into the Kerala coast, atypical of monsoon onset conditions.
Only the monsoon is changing over, and has instead brought up an anticyclone into play over Northwest India.
Too big in size, it is forcing flows to be southeasterlies to its south and around the ‘low.' The Busan, South Korea-based Asia-Pacific Climate Centre has said in its latest seasonal outlook that October-December would likely see above normal rainfall over South India, adjoining Bay of Bengal, South-East China and adjoining East China Sea.
This coincides with the northeast monsoon in India, and forecasts for individual months say October could be the wettest of them all.

Most of the country, except extreme South and South-East Peninsula and parts of the North-East, is expected to receive good rainfall during this month. Business Line surveyed a slew of specialised ‘low' tracking models - Canadian Meteorological Centre, GFS, UK Met Office, US Navy's NGP – to divine where the Wednesday's Arabian Sea ‘low' is headed.
All of them seemed to suggest it would be taken away to West or North-West from Lakshadweep by the southeasterlies. The system could likely be active for the next two to three days, with the odd model taking it as afar as to Oman/Yemen coast by October 5.
The European Centre for Medium-Range Weather Forecasts (ECMWF) tends to believe that the system might weaken over the next few days. But a sudden wave of activity expected to be triggered in the Bay could ignite it back to activity and cause it to track further north and strengthen.
Alongside, the Bay is also expected to throw up a counterpart system, to set up a trans-peninsular trough from October 6 and likely unleashing some organised showers.
Dedicated models are signalling negative Outgoing Long-wave Radiation (OLR) values indicating cloudiness and resultant rains over East Arabian Sea and South-West and South-East Bay during this period.

The ECMWF sees an eventful week unfolding with a reasonably big ‘weather system' shaping up in the Bay.
A landfall is now being projected along Chennai/South coastal Andhra Pradesh coasts.
The Roundy-Albany model that tracks cyclones sees the system (‘low'/depression) moving north from the South-East and adjoining South-Central Bay.
The Weather Forecasting Centre at the Central Weather Bureau, Taiwan, another specialised storm tracker, has zeroed in on two specific time-scale ‘windows' when the Bay would witness raised churn.
These windows are October 3-7 and October 7-11, when more than one circulation is shown wending their way from the Bay into the South-East Coast of India.
An India Meteorological Department (IMD) update on Wednesday said that widespread rainfall was reported from Coastal Karnataka, South Kerala and Andaman and Nicobar Islands during the 24 hours ending in the morning.
They were fairly widespread over Konkan, Goa and Tamil Nadu and scattered over Sub-Himalayan West Bengal, Sikkim, the Northeastern States, Gujarat, South Gangetic West Bengal and Lakshadweep.
A weather warning valid for Thursday said that isolated heavy rainfall may occur over Lakshadweep, Kerala, Tamil Nadu and Andaman and Nicobar Islands.
Forecast valid until Monday said that fairly widespread rainfall would occur over South Peninsular India while the wet session over North-East India may lift.
Meanwhile, experts are of the view that the Australian monsoon tends to follow the Indian monsoon pattern.
In which case, the northern wet season for the country could get ‘very wet' and active, with La Nina conditions likely to produce an increased number of cyclones.

Monsoon withdraws from more parts of North-West India

South-West monsoon has withdrawn from some parts of Punjab, Haryana, Rajasthan and Gujarat on Monday in what looks like the precursor to an unusually rapid exit from the entire upper half of mainland India.
The hurried withdrawal is being attributed to its ‘release' from a temporary pause enforced around September 16 half way to the east by contra-indicating weather systems.

This was the phase when the build-up to withdrawal ran itself up against hyperactive interaction between a deep-seated trough in the western disturbance with easterlies from the Bay of Bengal triggering torrential rains over Uttarakhand, Haryana and Delhi.
After the interaction spent itself out, the way has become clear for the dry westerly-to-northwesterlies to push into these areas and expedite the withdrawal process all over again.
An India Meteorological Department (IMD) update on Monday said that the withdrawal line passed through Amritsar, Hissar, Jaipur, Udaipur, Ahmedabad and Porbandar.

Conditions are favourable for further withdrawal from remaining parts of Punjab, Haryana, Delhi, Chandigarh, Rajasthan, Gujarat, Jammu and Kashmir, Himachal Pradesh and Uttarakhand and even parts of Uttar Pradesh and Madhya Pradesh during the next two to three days.
Satellite picture also indicated drying up of moist air over parts of North-West India, the IMD update said.
But the weather being set up in peninsular India by active circulations in the Bay of Bengal and the Arabian Sea could keep the withdrawing monsoon at bay for the time being.

Satellite pictures revealed the presence of convective clouds over parts of Arunachal Pradesh, Meghalaya, Tamil Nadu, North Orissa, South Chhattisgarh, South Konkan, Goa, South Peninsular India, East-Central and South Bay of Bengal, Andaman Sea and East-Central and South-East Arabian Sea. The IMD update said that during the last 24 hours ended Monday morning, widespread rainfall was reported from North Konkan, Goa and Coastal Karnataka.
It was fairly widespread over the Northeastern States, Madhya Maharashtra, Interior Karnataka, Kerala and Tamil Nadu while being scattered over Sub-Himalayan West Bengal, Sikkim, South Gangetic West Bengal and Lakshadweep.
The cyclonic circulation over Lakshadweep persisted from overnight.

International weather models suggested that occasionally wet weather would prevail over South Peninsular India until October 13, with another weather system forecast to take shape off South-East Tamil Nadu coast and just to the NorthEast of Sri Lanka.

The European Centre for Medium-Range Weather Forecasts (ECMWF) has predicted that a western disturbance could make its presence felt over the plains of North-West India by October 6.
This would be followed the very next day by the formation of a cyclonic circulation off South-East Tamil Nadu coast. It remains to be seen whether this could in fact mean the onset of the retreat monsoon (North-East or winter monsoon) over the peninsula.
In extended forecasts, the US National Centre for Environment Prediction (NCEP) sees this system driving rains across Tamil Nadu and Kerala as well as over parts of Karnataka and South Andhra Pradesh during the week ending October 13.
Meanwhile, an IMD weather outlook valid until Thursday said that fairly widespread rain or thundershowers would occur over Sub-Himalayan West Bengal, Sikkim, the North-Eastern States, Konkan, Goa, Tamil Nadu, Karnataka, Kerala, Lakshadweep and Andaman and Nicobar Islands.
They would be scattered over Interior Maharashtra, Andhra Pradesh, Orissa, Gangetic West Bengal and South Chhattisgarh.
But mainly dry weather would prevail over plains of North-West India, Bihar, Madhya Pradesh and Jharkhand indicating likely withdrawal of monsoon from these areas.
Extended forecast valid until Saturday said that fairly widespread rainfall would occur over South Peninsular India while rains would dry up over North-East India as well.

Climate Scam: NGO credibility hit a new low. The shame much worse than their Rwandan Genocide culpability

NGOs have moved from back stage to centre stage in world politics, and are exerting their power and influence in every aspect of international relations and policy making. They have in most part, been a positive force in domestic and international affairs. However, in recent times, various global Climate Justice Networks have popped up. These are platforms mainly constituted and controlled by Northern NGOs.
We as member of the NGO fraternity or general public seldom research their record of accomplishment; or ask awkward questions on northern NGOs policies; or chase facts behind their claims and publicity spin. One of the most basic questions as we dig deeper is what kind of credentials do these northern NGOs possess to champion justice issues. Simply put - are they committed to principles of justice as portrayed in their carefully cultivated public image?

If we go back to history, what we find is that they have a chequered past in terms of justice credentials. Rwandan Genocide until now had been regarded as the worst shame of NGO behaviour. This was genocide where an estimated 800,000 were massacred. The nineties saw NGOs soul-searching on such behaviour even as today NGO workers remain mentally scarred of experiences such as Rwanda. Apparently lessons have not been learnt as we find that through their climate advocacy they have not only repeating the mistakes of the past but the shame hit a new low.

Maharashtra begins artificial rain project

For the small pockets of land in Maharashtra that received very modest rainfall on Saturday and Sunday, its was a man made gift of showers. Four very small pockets of land in Satara (Wadunj) and rural regions of Pune district (Daund, Baramati and Marinagar) received from a maximum of 11 millimeters (mm) of rainfall for 31 minutes on a 12 square kilometer tract of arid land to an almost abysmal 6.5 mm of rainfall for even lesser time.

Why the jubilation then? Because these regions fall within 10 most scarcity-hit districts of Maharashtra with no rains for the last three years. The state government has imported the requisite radar machines and other equipment at a cost of Rs.5.5 crore and hopes to continue creating artificial ‘November rains’ equipped with a Piper Cheyenne plane (light aircraft), armed with hygroscopic salts, for cloud seeding sorties over these and other scarcity hit regions.

Chief minister Sushilkumar Shinde said today: “The artificial rain is the outcome of an agreement signed between the state government and Ms Weather Modification Co through its subsidiary Ms Agni Aviation Consultants (Bangalore) on August 21, 2003. The equipment was imported and became operational on Saturday with the first experiment resulting in 11 mm of rainfall experienced over a 12 square km patch in Satara district for 31 minutes. The next day (Sunday) the same experiment was repeated in the three rural regions where around 6.5 mm of rainfall was recorded.

Cloud seeding is here to stay and will provide a shower of man induced artificial rainfall upon regions bereft of nature’s annual generosity. The state government has set up a control room in the Vidya Prathisthan located in Baramati from where sophisticated radar will monitor the availability of cumulus clouds drifting over the parched landscape that can be targeted and fueled with enough hugroscopic salts (shot into the base of the cloud).

Rains this season create records in Mumbai, Delhi, Jaipur & Dehradun

Mumbai - breaking 50 year record

Monsoon has created a record of sorts this year. The rainfall witnessed is well on course to be ranked as the highest ever recorded in the city. There have been a number of intense rain spells, yet the city life has not been thrown out of gear even once. The data of monsoon witnessed between 1999 and 2009 indicates that there had been at least two rain days every year when the city life was halted, a senior official from the civic disaster management cell said. The Santa Cruz observatory has witnessed 3,309.2 mm rain this year, while the Colaba observatory has received 3,160.5 mm. A Met department officer said that with there being still some time before the monsoon withdraws, the rainfall-recorded is on course to be the highest ever. According to a senior official, the Santa Cruz observatory had recorded about 3,400mm rainfall in 2005, the year when an unprecedented rain event on July 26 saw a downpour of 944 mm. The second-highest rainfall recorded by the suburban observatory was 3,281.7 mm in 1958. The Met officials also suggested that the Colaba rainfall has already surpassed all rain records set in the past 50 years.

Dehra Dun - breaking 44 year record

The monsoon rainfall broke a 44-year-old record in Dehra Dun by registering a whopping 3088 mm of rainfall this season. Met Director Anand Sharma told PTI that the previous highest record was in 1966 when the Doon valley recorded 2930 mm of rainfall. Before 1966, records regarding monsoon rains are not available, he said. With heavy rains lashing Dehra Dun, several rivers in the valley were on spate which include Rispana, Bindal and Asan. Nine of the total 13 districts of Uttarakhand have received excess rainfall this monsoon season.

Jaipur - breaking 14 year record

Breaking a 14-year record, Jaipur received 781.2mm rain this year till Wednesday. Going by the Met department’s prediction, as the monsoon is still active in the state and will last till the end of the month, the figure is likely to change in the coming few days. According to officials of Indian Meteorological Department, Jaipur receives around 500 mm rainfall in normal circumstances. The last time it had rained so much was in 1996, when the showers had been plentiful to the point of becoming an abnormality. Jaipur city had then received 850 mm rain between June and September. Looking at the conditions of this year, Jaipur is heading towards and abnormal spell of monsoon. "The district has already received 40% rain in excess of the normal this year," an irrigation official said. The comparison becomes obvious with last year's rainfall chart when Jaipur received less than 300 mm rain and had to be included among the scarcity-hit districts of the state.

Delhi - breaking 32 year record

Records shows this is the wettest monsoon in Delhi since 1978. Rainfall since June 1 has touched 1004mm higher than 965.1mm recorded during the monsoon of 1978. Sunday's rain also took Delhi's rainfall during September to 250.6mm, the highest since 1998 when 280.4 mm was recorded. Last year, the figure had settled at 588 mm. Delhi recorded 455.1 mm rain in August, more than double its normal average of 225.8 mm. With 10 days remaining in the month, September too is poised to break records having recorded around 280mm more than normal.

LA NINA & NEM 2010

La Niña strengthened during August 2010, as negative sea surface temperature (SST) anomalies reached at least -1oC across most of the equatorial Pacific Ocean by the end of the month. Consistent with this evolution, the subsurface heat content (average temperatures in the upper 300m of the ocean) decreased further, reflecting the additional cooling of sub-surface waters east of the International Date Line.. Also convection was enhanced over Indonesia, while remaining suppressed over the western and central equatorial Pacific. The pattern was associated with the continuation of enhanced low-level easterly trade winds and anomalous upper-level westerly winds over the western and central equatorial Pacific. Collectively, these oceanic and atmospheric anomalies reflect the strengthening of La Niña.

  1. During last week the equinoctial Pacific SST have been NEGATIVE:
  2. LA NINA is expected to last during this Northern Hemisphere winter [2010-11]
  3. Though Indonesian region convective activity is expected to enhance, sleek of this convective belt into Bay is NOT predicted.
  4. There is chance that cold tongue may cross and sleek into western Pacific unto Indonesia.

Look out: Record Breaking La Niña Occurring?

Direct Report from The Hockey Schtick:
From a discussion board at NOAA comes this graph showing the developing La Niña of 2010 might be a record breaker. La Niña causes multiple global climate disruptions including a drop in global temperatures and extreme weather events around the globe, which no doubt will still be conveniently blamed on mankind's evil ways. The last 2 times of record-contending La Ninas in 1954 and 1973 were during the global cooling scare.* (see vagaries' note below)

The most recent (July-August) MEI value shows a continued drop from earlier this year, reaching -1.81, and 2.35 standard deviations below April-May, both record-fast drops for this time of year. In fact, the three-month drop set a new all-time record for any time of year, beating a drop in 1998.

ZERO HEDGE reports:
The most recent MEI rank (2nd lowest) is clearly below the 10%-tile threshold for strong La Nina MEI rankings for this season. One has to go back to 1955 to find stronger La Nina conditions for this time of year in the MEI record, and back to September-October 1975 for lower MEI values at any time of year.
We have one heck of big La Nina that has formed very quickly. We have not seen conditions like this in 55 years.

What does it mean for the Asian Weather:
La Nina brings warm water to the western Pacific. This will result in big storm after big storm hitting into China/Indonesia. So far there have been 11 typhoons to hit Asia this season. The most recent is Fanapi. It is about to make a mess of southern Taiwan. From there it is off to China. This powerful La Nina will continue for at least four more months. It is likely that it will end as quickly as it appeared. That transition will bring us violent storms. These in turn can send a whole lot of pulses, read systems, into the Bay, and result in strenghtening the NEM.
And the rest of the World:Look out for an extra cold winter and some cold water splashed on the claim "2010 is the hottest year ever."

Why is this La Nina cycle so strong? I have no clue. Nor do the people who study global weather. The strength of this ENSO cycle is no doubt related to that phenomenon.

A super-drencher upper air cyclonic circulation persisting over North-East Rajasthan still has what it takes to coerce seasonal westerlies scoop up moisture from far-off Bay of Bengal and dump it over North-West India.
An itinerant western disturbance has been interacting with monsoon easterlies spawned by a low-pressure area and originating from the Bay over the past few days.

The India Meteorological Department (IMD) has warned of the possibility of isolated heavy rainfall over Himachal Pradesh, Uttarkhand, Punjab, Haryana, Chandigarh, Delhi, North Rajasthan and West Uttar Pradesh for at least two more days.
The last 24 hours ending on Wednesday afternoon reported widespread rainfall over Himachal Pradesh, Haryana, North-East Rajasthan, Sub-Himalayan West Bengal, Sikkim, Coastal Karnataka and Lakshadweep.
It was fairly widespread over Uttarakhand, Punjab, Uttar Pradesh, the North-Eastern States, Gangetic West Bengal, Interior Karnataka and Tamil Nadu, Hardoi, Azamgarh, Gaya, Bankura and Sagar Islands.

International weather forecasters see the possibility of year 2010 monsoon, now on its final leg, lashing its tail over the south peninsula from this weekend.
As on Wednesday, the season has delivered 104 per cent rainfall, only two percentage points away from hitting the ‘upper circuit' as estimated in IMD's long-range forecast.
Most weather models see a phase of negative outgoing long wave radiation (OLR) enveloping Eastern and South-East Arabian Sea and contiguous Central Equatorial Indian Ocean and South-West Bay of Bengal from this weekend.
Negative OLR means less terrestrial radiation escaping into the atmosphere thanks to the presence of cloudiness over the region.

The setting resembles monsoon onset conditions except that a cyclonic circulation sitting over the Bay and entering the Tamil Nadu coast would drive in easterlies over the peninsula to trigger the rains.
The Climate Prediction Centre (CPC) of the US National Weather Services is of the view that Peninsular India would slip under end-of-season monsoon rains during the week ending September 29.
Extended forecasts indicate that these rains could continue into the next week (September 30 to October 6) as well.
International Research Institute (IRI) for Climate and Society sees above normal rainfall for an area surrounding South Interior Karnataka until Saturday.
Contiguous regions of Tamil Nadu and Rayalaseema are also expected to witness fairly widespread to scattered rains, the IRI said.
In the North, heavy to very rains have been forecast over Nepal, East Uttar Pradesh, Bihar, Gangetic West Bengal and North-East India.
An IMD update on Wednesday showed the presence of convective clouds over parts of Himachal Pradesh, Punjab, Haryana, North-East Rajasthan, East Uttar Pradesh, North Bihar, South Chhattisgarh, South-East Arabian Sea, South-East Bay of Bengal and Andaman sea.
The IMD has also located an upper air cyclonic circulation over South Coastal Tamil Nadu and neighbourhood.
Its forecast valid until Saturday said that fairly widespread rain or thundershowers are likely over Jammu and Kashmir, Himachal Pradesh, Uttarkhand, West Uttar Pradesh, Punjab, Haryana, Chandigarh, Delhi and North Rajasthan during the next two days before gradually lifting.
Fairly widespread rainfall would also occur over the North-Eastern States, Bihar, West Bengal, Sikkim, South Peninsular India, Lakshadweep and Andaman and Nicobar Islands during this period.
Extended forecast until Monday indicated that the fairly widespread rainfall would continue over the Northeastern States and South Peninsular India.

Es Safa Volcanic Field, Syria

Es Safa is a striking basaltic volcanic field located to the southeast of Damascus, Syria. It lies within the larger Harrat Ash Shamah—the largest volcanic field on the Arabian tectonic plate. Harrat Ash Shamah parallels the Red Sea and extends from northeastern Israel, through southern Syria and Jordan, and into Saudi Arabia, covering an area of over 50,000 square kilometers (19,000 square miles).
Es Safa contains numerous vents that have been active during the Holocene Epoch (beginning approximately 12,000 years ago). The most recent recorded activity was a boiling lava lake observed in the area around 1850. The dark lava flow field (center) likely represents the latest activity of the volcanic field, and is emplaced over older, lighter colored flows. The older flow surfaces also have light tan sediment accumulating in shallow depressions, in contrast to the relatively pristine surfaces of the darker, younger flows.
Cinder cones are scattered throughout the Es Safa field, but many are aligned along northwest-southeast trends that likely indicate faults through which magma rose to the surface. Two such alignments are visible at image left. To the southeast (image right) a small reservoir feeds water distribution ditches extending northwards.

La Nina in progress

Continuing a trend that began earlier in the year, La Niña conditions strengthened through the summer of 2010, evidenced by a streak of cool water across the equatorial Pacific Ocean.
Acquired by the Ocean Surface Topography Mission/Jason-2 satellite, this map shows a 10-day average of sea-surface height centered on September 6, 2010. Because water expands with rising temperatures, satellites can use sea-surface height as a proxy for temperature. Areas where the water surface is higher (and therefore warmer) than average are shades of red-brown, and areas where the water surface is lower (cooler) than average are blue. Normal conditions appear in white.
The El Niño weakens the westward trade winds that normally blow over the eastern tropical Pacific Ocean. Those winds keep eastern Pacific waters cool and concentrate warm waters in the western Pacific. A weakening of trade winds enables warm waters to gradually spread eastward, heating up the central Pacific. La Niña typically follows El Niño, and causes essentially the opposite conditions. La Niña strengthens the trade winds, spreading cool water from the South American coast to the central Pacific. This see-saw pattern of El Niño and La Niña can drive large-scale weather changes, especially in the tropics.
This map reveals a broad swath of cool water stretching from South America to New Guinea. The ocean is not, however, uniformly cool. Pockets of warm water are mixed with the cool, particularly in the western Pacific. Warmer waters in this region can lead to increased rainfall, and La Niña conditions may have played a role in the devastating floods in Pakistan during the Northern Hemisphere summer of 2010.
Over the eastern Pacific Ocean, cooler waters lead to less moisture along the coasts of North and South America. So as more rain pounds some parts of the globe, La Niña conditions can deepen drought in others. By the time La Niña conditions intensified in September 2010, the southwestern United States had experienced more than 10 years of mostly dry conditions. A release from NASA’s Jet Propulsion Laboratory reported that the American Southwest might experience not only drier conditions, but also intensified wildfires under strong La Niña conditions.

10 tell tale signs that the global warming is a dying hoax.

Global warming hysteria, whose gravy train INGOs and environmental organizations jumped into for the last decade or so, has run its course. Climate alarmism is dying a slow and painful death. Here are some telltale signs that it is in its deathbed, grasping for its last breath:

1. Re-branding exercises

We live in this age of advertisement where if something isn't working, the first remedy is often to change the offending name. Repeated attempts to re-brand global warming are one of these. Global warming first metamorphosed as “climate change”. This worked for some years but such was the gross misuse and abuse of the term that the public soon developed allergic to this term too and thus the desperate search for an alternative term in the last few months. Some alternatives recently floated are “climate weirdness” and “climate disruption “, the last coined by President Obama’s Science Czar John Holdren.

Brief summary of meteorological facts of the North East Monsoon...
season about to change between the SWM and NEM ...

Overall rainfall improves to 103%

Seasonal rainfall for the country as a whole as on Friday (September 17) improved further to 103 per cent as the southwest monsoon got busier in East and Northeast India.
Significantly, at -19 per cent deficit, this geographical region also managed to steer itself into the ‘normal' category as per India Meteorological Department (IMD) norms.

Individual deficits
But individual deficits in the Met subdivisions of Jharkhand (-43 per cent), Gangetic West Bengal (-33 per cent), Assam and Meghalaya (-25 per cent) and Bihar (-22 per cent) had their own tales to tell.
Overall, the country now has five rain-deficit Met subdivisions as on date, of which, four falls within East and Northeast India region.
The only one left is East Uttar Pradesh, which comes falls within the Northwest India region, but which lies contiguous to the rain-scarce Bihar.

Crop condition
Crop condition is improving in rain-scarce Bihar and Jharkhand due to receipt of delayed rainfall over the last two weeks, according to the latest agro-met advisory bulletin issued by IMD.
Harvest prospects look good due to the well-distributed rainfall, the bulletin said. There is significant improvement in the rainfall condition in West Bengal, particularly in Gangetic West Bengal.
Except the few districts that stayed out of the rain belt, most others received good rain. Standing crops has improved in the districts where sowing was delayed due to receipt of poor rain during earlier part of the season.
Farm advisory
Farmers who have kept the lands fallow or lost crops due to deficient rain have been advised to sow specified crops for specific regions and make most of the rainfall received and likely to occur during the next few days.
In Jharkhand, farmers may sow early mustard and ‘toria' as sole crops and early mustard with vegetable pea and ‘toria' with vegetable pea as intercrops.
Crops partially affected due to less rainfall in some districts of Uttar Pradesh are now in reasonably good condition due to recent rainfall.
Water logging condition has been reported afresh from South Telangana (Hyderabad, Medak, Rangareddy and Nalgonda districts). Farmers are advised to drain out excess water from the fields.

Widespread rain
The 24 hours ending Friday afternoon saw widespread rainfall being reported from Uttarkhand, an IMD weather update said.
It was fairly widespread over Uttar Pradesh, East Madhya Pradesh, Chhattisgarh, Vidarbha, Orissa, Bihar, Jharkhand, West Bengal, the Northeastern States, Konkan, Goa, Coastal Karnataka, Coastal Andhra Pradesh and the Andaman and Nicobar Islands.
Satellite imagery showed convective (rain-bearing) clouds over parts of East Uttar Pradesh, West Bengal, West Madhya Pradesh, Bihar, Nagaland, Manipur, Mizoram, Tripura, Orissa, Andhra Pradesh, Interior Karnataka and the Bay of Bengal.
As expected, a fresh low-pressure area sprung up over West-central and Northwest Bay of Bengal. Associated cloud bands extended to coastal areas of Orissa and North Andhra Pradesh by the evening.
Towards the Northwest, a western disturbance is expected to impact the western Himalayan region and adjoining plains of Northwest India during the next three days.
The IMD has warned of heavy to very heavy rainfall at a few places over West Uttar Pradesh and Uttarkhand during the next two days.
Isolated heavy rainfall would also occur over East Uttar Pradesh, East Madhya Pradesh, Chhattisgarh, North coastal Andhra Pradesh and Orissa during this period. Forecast valid until Wednesday spoke about the possibility of a decrease in rainfall over parts of Northwest India and East India.
Fairly widespread rainfall would continue over Northeastern States and parts of Central India, the IMD said.

Sunday, September 19, 2010

With the season about to change between the SWM and NEM, an attempt at a brief summary of meteorological facts of the NEM.

The SWM onset is well defined, and follows a well coursed out Northward progress. And can be discerned with reasonable accuracy on charts.
For the NEM, it is not so.
In fact, on many occasions, there is no clear indication between the widhrawing SWM and setting NEM. Often one tends to merge into another.
So, setting a date for the commencement of NEM is difficult, and sometimes not possible.

For the SWM, its origin source, its "Power House", is at the Mascrene Highs off Madagascar. The NEM has its origin round a large anti-cyclone over Siberia.

The Upper winds during the NEM across the Bay are in a clockwise direction.That is an anti-cyclone is formed. At a level of 500 mb, the centre of the anticyclone shifts to central Burma region.
The Upper Air temperatures show a Nortward gradient in the NEM.Near 10N it is normally warmest, and dropping by 8c at 30N.

Jet streams at 200 hpa are common to both the monsoons.
In the SWM, the Tropical Easterly Jet stream dominates the Peninsula, while the Sub-tropical Westerly Jet Stream is the feature of the NEM.

The normal Sea Level Pressure during the NEM is a large system of low pressure over the Central Bay. It can extend into the Indian Peninsula as a trough.Towards the end of November,there is a shift southwards of this extended low.
The general variations and fluctuations in intansity of this low pressure, governs the rainfall. When the trough is well defined, and the low is well marked, rainfall over the southern peninsula is good.
During the NEM, an occasional burst of cold air from the Siberian High develops a low pressure sysytems over the Equatorial regions of the South China Seas. These systems move slowly westwards thru Sarawak/Eastern Malaysia coast, and remnants of these cross over into the Bay and form depressions.

Most of the NEM rains depend on depressions and cyclones from the Bay towards the East Coast of India.

Dehra Dun breaks a 44-year monsoon record by registering a whopping 3018.3 mm of rainfall this season

The monsoon rainfall broke a 44-year-old record in Dehra Dun by registering a whopping 3018.3 mm of rainfall this season. Met Director Anand Sharma told PTI that the previous highest record was in 1966 when the Doon valley recorded 2930 mm of rainfall. Before 1966, records regarding monsoon rains are not available, he said. With heavy rains lashing Dehra Dun, several rivers in the valley were on spate which include Rispana, Bindal and Asan. Nine of the total 13 districts of Uttarakhand have received excess rainfall this monsoon season. During the past 24 hours, Dehra Dun has received 149.3 mm of rainfall.

Hurricane Igor

Tropical Storm Igor formed over the far eastern tropical Atlantic Ocean on September 8, 2010, the U.S. National Hurricane Center (NHC) reported. From its genesis locality southeast of Cape Verde, Igor traveled westward. Igor strengthened to a hurricane on September 11, becoming the fourth of the season. By 11:00 a.m. Atlantic Standard Time (AST) on September 13, Igor was a category 4 hurricane, packing maximum sustained winds of 150 miles (240 kilometers) per hour.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this natural-color image of Hurricane Igor at 12:40 p.m. AST (16:40 UTC) on September 13, 2010. Igor shows all the characteristics of a strong hurricane, including a distinct eye and spiral arms spanning hundreds of kilometers.
On September 13, the NHC forecast that Igor would continue moving toward the west at about 10 miles (17 kilometers) per hour. Late in the day on September 13, or early in the day on September 14, Igor was expected to turn toward the west-northwest. Although the storm’s intensity would likely fluctuate over the next 48 hours, it was expected to remain a powerful hurricane.

Landslide in Zhouqu, China

Tucked between the steep slopes of the Min Shan and the Bailong River in northwest China, the city of Zhouqu has a picturesque location. However, the intimidating natural beauty also carries a risk. On August 8, 2010, unusually intense monsoon rains triggered devastating landslides and floods that buried a densely populated area in the center of the city. As of August 17, China’s official news agency reported 1,270 deaths with 474 people still missing. This detailed image, from DigitalGlobe’s WorldView-2 satellite, shows the largest slide in the lower part of the city on August 10.
The slide terminates in a brown fan that extends into the Bailong River. Mud surrounds several of the buildings near the river’s edge and branches into adjacent streets. Some of this mud may have been deposited by flood waters that gathered behind the slide as torrential rain continued to fall. In the large image, which shows a wider area, the dark waters of Bailong River seeps around buildings across from the slide and up the wide road that runs along the river’s edge not far from the slide.
Moving away from the river, the mud has a rougher, more varied texture where the slide channeled through the center of the city. The smooth dark spots are probably water. Light-colored flecks are probably debris. The slide area widens again in the lower right corner, clearly covering blocks of buildings.
Slightly darker than the surrounding mud, streams snake across the surface of the slide. The large image reveals that the landslides followed the course of streams down the mountains and into the valley where Zhouqu was built. On the far right side of the large image, closer to the top of the slide and beyond the right edge of the web image, farmland surrounds the streams. The steep slopes on either side of the streams are bare of vegetation, possibly making them prone to landslides.

Following intense monsoon rains, a landslide struck Zhouqu County of China’s Gansu Province on August 8, 2010. By early September, the death toll stood at 1,765, Dave’s Landslide Blog reported, and this single event contributed to an unusually high worldwide death toll for landslides in 2010.
Weeks after the event, the landslide in remained visible to the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite. ALI captured this natural-color image on September 2, 2010. Bare earth forms a giant Y shape on the otherwise forested mountain slopes. The separate slides have coalesced into a wide river of mud flowing into town. Clouds leave part of the landscape in shadow, but the landslide remains discernible all the way to the river at the bottom of the valley.

Rains may intensify over Delhi from Thursday ...

IMD proposes nowcasting services...

Rains may intensify over Delhi from Thursday

India Meteorological Department (IMD) has forecast isolated to scattered rain or thundershowers for parts of Northwest India, including Delhi, which will gain in intensity from Thursday.
An IMD forecast valid until Thursday said that isolated to scattered rain or thundershowers would also occur over east Rajasthan, Haryana, Chandigarh, Himachal Pradesh and Jammu and Kashmir during this period, before scaling up.
This is being attributed to the activation of a western disturbance that will deepen in due course to embed a likely low-pressure area, updated forecast by European Centre for Medium-Range Weather Forecasting (ECMWF) said on Tuesday.
Fairly widespread rain or thundershowers has also been forecast for East and Northeast India, the West Coast, Uttar Pradesh, Uttarakhand, Madhya Pradesh, Chhattisgarh, Vidarbha, Andhra Pradesh, Andaman and Nicobar Islands and Lakshadweep during this period.
IMD is also launching ‘nowcasting' facility for Delhi to coincide with the Commonwealth Games and its Web site featured a link showing a relevant page in construction.

Nowcasting is a system that can predict climate conditions for a very short period — one to four hours — using data from Doppler weather radars.
Smaller events such as individual showers and thunderstorms can be forecast with reasonable accuracy by using this facility as also are features too small for a computer model to resolve.
Meanwhile, the last 24 hours ending Tuesday morning saw fairly widespread rainfall over Tamil Nadu, the Andaman and Nicobar Islands, South Coastal Andhra Pradesh, Gangetic West Bengal, Himachal Pradesh and Uttarakhand.
It was scattered over Kerala, Chhattisgarh, East Rajasthan, Assam, Sub-Himalayan West Bengal and Haryana during this period.

Satellite imagery revealed the presence of convective (rain-bearing) clouds over parts of Uttar Pradesh, Bihar, Jharkhand, Gujarat, Chhattisgarh, Vidarbha, East Madhya Pradesh, Gangetic West Bengal, Assam, Meghalaya, North Orissa, Andhra Pradesh, East Rajasthan, Tamil Nadu, Karnataka, Kerala, the Andaman Sea, the Arabian Sea and the Bay of Bengal.
The trough along the Southeast Coast continued to be prominent on Tuesday with a churn beginning to build over Northwest Bay of Bengal. The ECMWF has maintained its watch for a low-pressure in this basin over the next few days.
Confluence of westerlies from a prevailing western disturbance and monsoon easterlies from the Bay of Bengal over the eastern half of Northwest India and the entire East India has helped sustain an active belt of heavy to very heavy rains over the region.

International Research Institute (IRI) of Columbia University has retained its outlook for heavy to very heavy recorded rains for Northwest India except Jammu and Kashmir and neighbourhood for six days ending Saturday.
On Tuesday, it added South Coastal Andhra Pradesh and adjoining Rayalaseema to this list, apparently from the building ‘low.'
Meanwhile, IMD traced a persisting upper air cyclonic circulation over Haryana and neighbourhood.
Meteorological analysis suggests that a fresh western disturbance is likely to affect the Western Himalayan region from Friday, it said.

A warning valid for Wednesday said that isolated heavy to very heavy rainfall would occur over Himachal Pradesh and Uttarakhand.
Isolated heavy rainfall has been forecast over Uttar Pradesh and Gangetic West Bengal as well during this period.
Extended forecast until Sunday spoke about the possibility of widespread rainfall over Jammu and Kashmir, Uttarakhand, Himachal Pradesh, West Uttar Pradesh, Haryana, Chandigarh and Delhi with isolated heavy falls.
Fairly widespread rainfall has also been forecast over Sub-Himalayan West Bengal, Sikkim, the Northeastern States, Central and adjoining North Peninsular India.
