June 14 The monsoon has been stuck for exactly a week after it revived from the shock administered by Cyclone Aila, and is expected to stay as such for another three to four days.
This would delay its advance into major farming regions in the east, southeast and peninsular India, India Meteorological Department (IMD) said on Sunday.
TROUGH OF LOW
The only redeeming feature as on date was the presence of a trough of low pressure over north Bay of Bengal. The European Centre for Medium-Term Weather Forecasts sees some activity brewing here within the next five days.
The IMD said that increase in rainfall is likely along the west coast and over the Andaman and Nicobar Islands from Wednesday apparently as a prelude to the churn in the Bay.
To the peninsular west, a persisting offshore trough linking south Karnataka coast to Kerala coast would continue to cause fairly widespread rainfall over coastal Karnataka, Kerala and Lakshadweep.
The Regional Met Centre, Chennai, said in its update that rainfall occurred at many places over Kerala and at a few places over Lakshadweep and coastal Karnataka during the 24 hours ending Sunday morning.
Isolated rainfall occurred over Tamil Nadu, coastal Andhra Pradesh, Rayalaseema and interior Karnataka also.
MORE RAINS
Rain or thundershowers are likely at many places over Kerala and Lakshadweep, and at a few places over coastal and south interior Karnataka, coastal Andhra Pradesh, Rayalaseema and interior Tamil Nadu for two more days.
Isolated rain or thundershowers are likely over coastal Tamil Nadu, Puducherry, north interior Karnataka and Telangana.
Delay in monsoon over Bihar, Orissa, Jharkhand, Chhattisgarh, parts of Andhra Pradesh, Maharashtra, southern Gujarat, Madhya Pradesh and adjoining peninsular India has allowed heat wave conditions to develop.
On Saturday, the highest maximum temperature of 44.6 deg Celsius was recorded at Ganganagar. Severe heat wave conditions prevailed at isolated places in Vidarbha.
Meanwhile, Dr Karumuri Ashok, Senior Research Scientist at the Asia-Pacific Climate Centre, Busan, South Korea, has clarified that the forecast for a weak El Nino and positive Indian Ocean Dipole (IOD) over the next months was ‘experimental’ in nature.
MODEL DIFFERENCE
The APCC predictions for El Nino and IOD are only in research mode, produced once a season for the next six-months with collaboration from several research centres to arrive at a consensual coupled model prediction.
The APCC’s ‘operational’ prediction (based on mathematical models of atmospheric motions alone) is different from this ‘coupled’ (ocean-atmosphere) prediction, Dr Ashok informed Business Line.
“As per our operational prediction, rainfall signals for India for June-July-August are positive to near normal everywhere, unlike the coupled prediction,” he said.
The equatorial Pacific would still need to be constantly watched before any final word could be said about the development of any major weather-altering event.
‘NEUTRAL’, FOR NOW
Meanwhile, the Climate Prediction Centre (CPC) of the US National Weather Services said in its June-8 update said that ‘neutral’ conditions were present in the equatorial Pacific Ocean.
But current observations and dynamical model forecasts indicated that conditions were favourable for a transition to El Nino conditions during June-August.
Since the beginning of May 2009, positive sea-surface temperature (SST) anomalies have been observed across the equatorial Pacific.
During the last four weeks, equatorial SSTs were above-average across much of the equatorial Pacific Ocean, with the largest positive anomalies evident in the eastern and western Pacific, it said.

Severe Weather Pattern Threatens Asia-Pacific Region
original from:: http://www.voanews.com/english/2009-06-12-voa6.cfm
Climatologists are warning that an El Nino weather pattern, which can spark severe floods, forest fires and droughts, could develop in the coming weeks across the Asia-Pacific region.
An El Nino event occurs when water temperature in the eastern part of the Pacific Ocean rises abnormally. The movement of warmer, moist air to the east leaves drier weather in the western Pacific.
The Climate Prediction Center in the United States has warned that after months of rising temperatures in the tropical Pacific Ocean, the onset of an El Nino pattern was becoming more likely between now and August. The water is now half a degree warmer than average.
Researchers at Australia's Bureau of Meteorology agree that an El Nino event is likely. They say if recent trends in Pacific climate patterns persist, there is a strong chance that an El Nino pattern will emerge in the coming months.

Such conditions could be disastrous for farmers in Australia's drought-prone southeast who can expect little relief from years of below average rainfall.
The effects of such a shift in weather patterns would be felt across Southeast Asia.
Professor Matthew England, director of the Climate Change Research Center at the University of New South Wales, says Indonesia would likely have drastically less rainfall.
"The effects on Indonesia are actually even stronger," he said. "If you look at how El Nino affects all the nations around the Pacific Rim, Australia is often thought of prominently in that regard. But Indonesia and Southeast Asia generally see much drier conditions during El Ninos. In past El Ninos we have seen some very severe forest fires in Indonesia."
The most devastating El Nino occurred in 1997. It caused widespread drought in Australia and Indonesia as well as floods in Peru and Ecuador.
An El Nino event can also bring wetter weather to parts of the United States and can affect the monsoon season in India.
In an El Nino year, there are typically more hurricanes in the Eastern Pacific and, conversely, fewer such storms in the Atlantic.

News reports from Kanyakumari district and Monsoon
News reports about recent monsoon fury from Kanyakumari district.
Another Monsoon lull period from today
The monsoon has once again run into a brief lull after winds erred in direction and speed, but numerical weather prediction models indicated that the rains would revive from Wednesday.
The offshore trough from south Konkan-Goa persisted but the westerly to southwesterlies tended to become westerly to northwesterlies on approach except over the southern tip of the peninsula.
STRAYING WINDS
A prevailing western disturbance and its band of northwesterlies seemed to have entrenched itself down to central India and beyond, forcing the southwesterlies to stray.
But this would trigger isolated rain or thundershowers over Jammu and Kashmir, Himachal Pradesh and Uttarkhand. Isolated dust storm or thunderstorm has been forecast over Rajasthan.
Convective clouds were seen over east-central and adjoining southeast Arabian Sea, besides over north Andaman Sea and north and adjoining central Bay of Bengal across the peninsula, the IMD update said.
The Chennai Met Centre said that the monsoon was vigorous over north interior Karnataka and active over Kerala during the 24 hours ending Monday morning.
Forecast for the next two days, however, indicated the possibility of thundershowers at many places over Kerala, Lakshadweep and coastal Karnataka, and at a few places over interior Karnataka. Isolated rain or thundershowers have been forecast for Tamil Nadu, Puducherry and Andhra Pradesh.
A warning valid for the period said that isolated heavy rain is likely over Kerala and coastal Karnataka.
WAIT FOR MUMBAI
The northern limit of monsoon remained unchanged from Sunday’s alignment along Ratnagiri, Gadag, Anantapur, Ongole, Kalingapattinam, Paradip, Balasore, Bankura and Gangtok.
Latest forecast from the International Research Institute (IRI) at Columbia University suggests that the monsoon may not enter Mumbai until sometime after the June-10 normal.
The erratic rains are now expected to enter the metropolis around June 13 only, although occasional pre-monsoon showers are likely to occur during the run-up to this.
In fact, the IMD has said that rain or thundershowers are likely at a few places over Konkan and Goa, while being isolated over south Madhya Maharashtra over the next few days.
BAY ACTIVITY
The European Centre for Medium-Range Weather Forecasts (ECMWF) has assessed that the Bay of Bengal may be readying itself to host a typical monsoon ‘low’ from June 15 onwards.
The system might show up to northwest of Andaman and Nicobar Islands and might get embedded in a larger trough of low-pressure area during the next two to three days.
This is more or less corroborated by precipitation forecasts made by the US National Centres for Environmental Prediction (NCEP) showing gains for the west coast and the rest of the peninsula from June 16 to 24.
Convection is shown to spread from southeast to northeast Arabian Sea during this phase when rains would have covered the entire west coast. The Bay ‘low’ might spearhead rains into the peninsulas and set up an interaction with a counterpart to the west.
The offshore trough from south Konkan-Goa persisted but the westerly to southwesterlies tended to become westerly to northwesterlies on approach except over the southern tip of the peninsula.

Monsoon advances into Goa, parts of Konkan
The monsoon advanced to more parts of central Arabian Sea, Karnataka, entire Goa and parts of Konkan, India Meteorological Department (IMD) on Sunday.
The persisting ‘low’ over northeast Bay of Bengal and an offshore trough to the peninsular west from south Konkan to Kerala set up the platform for the spectacular northward progress of seasonal rains.
Sustained northward propagating convection (cloud-building activity) was observed over the Arabian Sea, opening up later in fairly widespread rains with heavy to very heavy falls over Karnataka, Konkan and Goa.
NORTHERN LIMIT
The northern limit of monsoon passed through Ratnagiri, Gadag, Anantapur, Ongole, Kalingapattinam, Paradip, Balasore, Bankura and Gangtok. Mumbai would be the next big port of call which models suggest would be covered in another three to five days.
The Chennai Met Centre said that the monsoon advanced into more parts of north interior Karnataka on Sunday. It has been active over Kerala, coastal and south interior Karnataka.
Rainfall occurred at most places over coastal Karnataka, Kerala and Lakshadweep and at many places over interior Karnataka. Isolated rainfall occurred over Tamil Nadu and Andhra Pradesh.
Forecast for the next two days said that rain or thundershowers are likely at most places over Kerala, Lakshadweep and coastal Karnataka, at many places over interior Karnataka and at a few places over interior Tamil Nadu, north coastal Andhra Pradesh and Telangana. Isolated rain or thundershowers are likely to occur over coastal Tamil Nadu, Puducherry, south coastal Andhra Pradesh and Rayalaseema.
A warning valid for the next two days said that isolated heavy to very heavy rain is likely over coastal Karnataka. Isolated heavy rain is also likely to occur over Kerala, Lakshadweep and interior Karnataka.
MAHARASHTRA RAINS
Forecast by the Climate Prediction Centre (CPC) of the US National Weather Services said rains could spread progressively to more parts of Maharashtra and Rayalaseema by June 12 even as fresh convection may break out over southeast Arabian Sea off the Kerala coast.
A week, hence, the CPC saw a new wave of rains marching in from east and east-central Bay of Bengal and looking to enter east peninsular India. The US National Centres for Environmental Prediction (NCEP) too has put out an almost similar outlook.
The NCEP persisted with its forecast for widespread rains for the west coast through June 14, with heavy falls forecast for the southern parts of Kerala.
Western Maharashtra could be bracing to share some of the spoils while the Vidarbha region, Telangana and the north Tamil Nadu may sit out. Renewed activity is signalled for the west coast, entire Bay of Bengal and most of the peninsula from June 15 to 23.
MONSOON FURY
According to a six-day outlook put out by the International Research Institute (IRI) for Climate and Society at Columbia University, northern Kerala and adjoining coastal Karnataka would bear the brunt of monsoon fury.
Meanwhile, an IMD outlook saw pre-monsoon thundershowers breaking out over parts of madhya Maharashtra while being isolated over Marathawada during the next three to four days.
Isolated thundershowers have been forecast also for east Madhya Pradesh, Chhattisgarh and Vidarbha.
Towards the north and northwest, a prevailing western disturbance is expected to cause rain or thundershowers at a few places over Jammu and Kashmir, Himachal Pradesh and Uttarakhand.
Isolated thundershowers are likely over East Uttar Pradesh and isolated dust storm or thunderstorms accompanied with squall over Punjab, Haryana, Delhi, north Rajasthan and West Uttar Pradesh.

Southern most village set to disappear
Erayumanthurai fishing hamlet, southernmost village in Kanyakumari district is the worst affected by sea erosion and is in the danger of disappearing from the map.
Located between the Arabian Sea, AVM Canal and the perennial Thamirabarani River, Erayumanthurai is very vulnerable for sea erosion. The sea has engulfed more than half its land eating away rows of houses, coconut trees and fishing equipment worth lakhs. During monsoon, the heavily flooded river enters the village, causing more damage. For the villagers, fishing is the only occupation and during such times, they are the worst affected.
However, the village continues to survive due to a weak and permeable wall, which is slowly collapsing as the sand from beneath continues to get washed away. A number of representations to the district headquarters and the Secretariat in Chennai has yielded no action.
Twenty years ago, the distance between the sea and the river was about 700 metres with eight rows of houses, besides a road, Erayumanthurai parish council member Dunston told Express. But now the distance was merely 50 metres with rows of houses, due to sea erosion.
He said in 1982, when an anti-sea erosion wall was constructed, the population was 7,000 and now it has dwindled to just 2,500.
Priest Ignatius Russel said: “Constructing a backwater on the west of the village is the only solution, but it has been objected by the neighbouring villagers, who fear that it would affect them in turn.”
Professor and oceanographer Vareethiah said construction of fishing harbours, power plants, industries, groynes or any other structure obstructing the course of the sea currents would have a reverse effect on the behaviour of the sea.
“For the past 25 to 30 years, Kanyakumari coast has been witnessing heavy erosion with Neerodi-Kurumbanai being severely battered. This can be attributed to the breakwaters and fishing harbour constructed at Vizhingam, Kerala,” he noted.
“People normally reckon that anti-erosion protection wall can solve the problem. But that only negates the dynamics of the sea currents. A seawall can protect the landscape only for a particular period of time after which the waves will start washing the sand from beneath. If the wall is not reinforced every year without fail, it will create more problems.”

India Monsoon Is Advancing Again
“India’s monsoon, which accounts for four-fifths of the country’s annual rainfall, revived after a two-week lull and is set to progress toward the main cotton and rice growing areas, the weather bureau said.
Rains moved further into the southern state of Karnataka and covered the entire province of Goa and some parts of the Konkan region on the west coast, the India Meteorological Department, said in a statement on its Web site. The advance of the monsoon, which set in over Kerala state a week before usual this year, stalled after tropical cyclone Aila lashed the nation’s coast on May 25.
Timely rains help boost yields of crops including rice and corn that are sowed after the onset of the monsoon. Increased production will help Prime Minister Manmohan Singh’s government to keep its promise of distributing grain to the poor at below market prices.
The weather bureau predicts “scattered to fairly widespread rainfall activity over the west coast of India and the northeastern states” in the next 48 hours.
Rains covered some regions of Kerala, Tamil Nadu, Karnataka and Andhra Pradesh, and parts of Orissa, West Bengal and Sikkim by May 25, the IMD said. The monsoon was moving toward Maharashtra, the biggest sugar cane-producing state and the No.2 cotton grower, when it stalled.
India received 12.5 millimeters (0.5 inch) of rain in the week ended June 3 compared with a 50-year average of 19.2 millimeters for the period, the weather office said June 4.
Rains were 32 percent below normal at 91 millimeters compared to the 134.5 millimeter average in the three months to May 31, the agency said. Precipitation was below average in 24 of 36 weather zones last week, and normal in the rest.”

Now 2 LOW systems on both sides...
After yesterday's "90B" over the central Bay, now we are joined with another LOW system over the South-east Arabian sea "91A".
Here's the latest satellite pic.
Latest GFS models did not predict any formation of cyclone or even a depression with the present 2 systems "91A" and "90B".
Chennai:
We'll experience wind gusts thru the day from South-west.
Temperature will be around 39 deg.
And at around 5 pm we will see some thunder cells over the West-south-west and 60% chance we might get a shower or two.
This is the weather forecast for Chennai for next 2 days.

Low pressure "90B"
Bay is active again after 15 days from Cyclone Aila.
Now it's a Low pressure system "90B" and this is also a potential Cyclone system, because it's got good monsoon air current and having a huge cloud mass.
Here's the latest satellite pic... which shows the cloud mass and some signs of circulation.
This system will surely revive the Arabian wing of the south west monsoon.
