Upcoming W-central Arabian sea LOW >> "few other models which do not agree and show NO low formation" ..
RT @rajugana: @weatherofindia Migratory storks’ early arrival raises monsoon hopes

A couple of International Forecasting Models estimate a low pressure to form in the Arabian Sea, around 10N and 60E by the 1st of June. There are few other models which do not agree and show NO low formation in the region around that time frame.

With 2 diverse opinions by several International Models, it becomes confusing for the average reader to actually judge or estimate the fact, especially at a critical time when the SWM is advancing along the West Coast of India.

Vagaries' View: 
Citing the "patch" of higher SST in the Central regions of the Arabian Sea (around 55-60E), it is possible that a low pressure system can form in the region by the 1st/2nd June. 
But, as it travels North, it can encounter a slightly colder sea, thus limiting its growth. The low, initially could be at 1000 mb, can deepen to 996 mb by the 4th of June, before it starts weakening again from the 5th.

If the Arabian sea circulation pops up on 30-May or 1-Jun then only a weak monsoon current will reach Kerala coast on 1-Jun.
COLA models still suggest a strong circulation over W-central Arabian sea on 1-June and will move N-N-E ..

SWM has further moved into Southern Sri Lanka. Maldives and Northern Andaman Sea.
Galle in Sri Lanka recieved 63mms of rain and Ratnapura got 30 mms on Saturday, 26th, while Colombo measured 15 mms.

Cross Equatorial Flow has picked up considerably in the Bay and Arabian Sea. Winds over 30-35 knts are seen gushing Northwards off the Somali Coast, and 40 knts winds are seen in the Bay.
Winds off the Sri Lanka coast have picked up considerably.

Today's SST map is reproduced here to show the Sea temperature not falling sufficiently yet along the Somali coast. It is presently around 24c. Now, this difference with the Central Arabian Sea plays a key role in cloud formations off the Western Coastline of India in the Central Arabian Seas. The SST along the Somali coast will rapidly fall to around 18/20c in the next 10 days.

But the current fall is sufficient to help form Monsoon clouds around the Maldives. Cloud formation near Sri Lanka is gathering, and in next 24 hrs, wind speed along the Sri Lanka coast is estimated at 35 mph (in gusts). 
A slight fall is seen in the Bay water's SST.

The ITCZ is slowly moving up, but is still around the Equator regions, and in the 5N region in the Bay sector.

SWM should set in over Sri Lanka within next 24 hrs, that is by the 28th May. 

The Seasonal Low seems to have strengthened. We see today's pressure at 998 mb. Getting gradually ready enough to create a gradiant to pull up SW winds into the mainland. The day temperatures on the Sub-Continent Northern plains are on the higher side since Wednesday, with the average the day's highs are around 42/43c. Across in Pakistan' Sindh region, the core area for the formation of the low, the highest was 46c on Saturday. M-5 effect was expected bring about a slight fall in the day readings(reported in Vagaries yesterday).

M-5 is seen moving away from India. WDs should slow down now, as the jet streams at 200 hpa are re-grouping fast into position. 

The Jet Stream Westerlies are almost upto the 15N line, and the "High" formation is taking shape East of Bangladesh. Expected movement of this "High" should be inland towards MP for perfect position.

The Bay sector SWM has been stagnant, and not picking up as expected from a "setting in" Monsoon. Its lack of systems could be attributed to M-4/5. Strong westerly currents prevent the formation of lows to move into the bay and towards the Indian mainland. They divert the forming currents.
As SW winds should pick up speed in the next 2 days, SWM "in situ", could advance further into the Bay. Better before another WD reaches the region to spoil the  "party".

Conclusion: SWM advancing into Sri Lanka by 28th (late by 3 days). 
Advance into Kerala around Vagaries' expected date, 3rd/4th June. But, further advance would need monitoring. 
Possibly into Coastal Karnataka and Southern TN regions by the 7th of June. 
South Konkan and Goa around 8th June, and Mumbai by 13th/14th June.

SWM has feebly moved into the Southern Bay Region. 

SWM will start covering the complete Bay Islands from the 23rd, and subsequently, riding on a system, reach the NE states by the 1st of June. 
SWM could be expected over the Maldives by the 23rd of May.(Normal date 20th). Over Sri Lanka around the 27th of May.

I would estimate the SWM to advance into Kerala around the dates initially estimated by Vagaries : June 3rd/4th could be the date for Kerala, but remain weakish till the middle of June in coastal Karnataka and Kerala.

Initially, riding on a strongish MJO wave, the SWM could precipitate good rains in Kerala. The further current into Kerala would be "reluctant" to move ahead in a weak MJO, as International forecasters predict the MJO phase in our seas to become weak after the 10th of June. This weak phase could last till 20th of June say the forecasts. 
Nevertheless, the SWM could progessively advance into coastal Karnataka 48 hrs from 5th June. SWM could advance into interior Karnataka, Goa and S.Konkan by the 9th, and Mumbai by the 11th/13th. of June.

International Climatic Models Turn Even More Pessimistic of a “Normal” Indian Monsoon

We are seeing possible early signals of an emerging El Niño. Large swathes of land within the country are already facing drought like conditions. Meanwhile in Peru, scientists are perplexed over the mystery death of over 3,000 dolphins. What causes marine mammals to die en masse? The US climatic agency, NOAA notes a number of possible causes, including infectious disease, parasite infestation, starvation (associated with El Niño events), pollution, injuries and algal blooms that release bio-toxins. The El Niño remains their primary suspect.
Asked whether he was worried about the El Niño playing spoil sport with the Monsoon, the India Meteorological Department (IMD) Director General LS Rathore told the media that :
"Yes there are chances of El Nino phenomenon emerging in the Pacific which may not favour rains in the month of August-September. But overall monsoon is likely to be normal. El Niño is just one of the parameters being considered while forecasting".
First 30c Minimums of 2012 Reported from Sub-Continent on 11th May !

'Monster sunspot' could bring solar flares and major disasters

A group of sunspots 11 times wider than the Earth turned to face our planet, raising the possibility of solar flares and auroras tonight. The sunspot cluster - shaped a little like the islands of Hawaii - is much larger than Earth. It measures 100,000 miles from end to end, while the diameter of the Earth is approximately 7,900 miles. The Sunspot Region 1476 became visible over the weekend and two coronal mass ejections (CMEs), where a portion of the sun's atmosphere breaks off, erupted on Tuesday. 

The CMEs blasts could arrive on Earth later today and cause moderate geomagnetic storms later and auroras in the higher latitudes, according to NOAA's Space Weather Prediction Center. 

The CMEs are travelling at 1.5 million miles per hour but, since they are only partially directed at Earth, they aren't expected to affect communications satellites or other equipment susceptible to space weather. (Special filters are needed for viewing the sun directly to protect the eye, notes

Monsoon Watch-Seasonal Low parameter:

With the heat factor still lacking absolute "full strength", in the Northern regions, the Seasonal Low core in the Thar Desert is now somewhat "unsteady", with a core pressure at 1002 mb, and requires to spread more westwards, rather than east. This (pulling Eastwards) is happening due to M1. 

The heat waves are still missing, with the minimums still showing vast regions in the below normal range. By this time each year, vagaries normally charts the "above 30c" minimums. But this year as yet, forget 30s, we are still barely reaching 25s in the night, with the odd one out in the NW plummeting to below 20c.
And the days ? 45c is just about getting its foothold!

Polar Bear Extinction: Deconconstructing the Scientific Hoax;

In an age in which emotional narratives often trump facts, the polar bear quickly became the icon of the climate alarmist movement. The frame of a cuddly polar bear clinging on to a swiftly melting tiny ice floe tended to immediately rake up a flurry of emotions all sympathetic for a creature, apparently portrayed as helpless to starve off the danger of its imminent drowning.

Al Gore, former US Vice President, used the above frame in his controversial documentary “The Inconvenient Truth”. All these publicity spurred the frame going viral over the internet and succeeding in recruiting tens of thousands to the climate change cause. It however also spawned an ever increasing band of climate critics. Science, the renowned international scientific journal selected the frame in its editorial “Climate Change and the Integrity of Science” to counter this growing worldwide trend of “climate scepticism”:

"We are deeply disturbed by the recent escalation of political assaults on scientists in general and on climate scientists in particular. All citizens should understand some basic scientific facts."

But they didn’t factor into their calculations, an encounter with my pal, James Delingpole of The Telegraph, a leading newspaper in the UK. James’ brilliant investigative work exposed the frame as a photo-shopped graphic! Instead of helping to refute the allegation, this frame ended up confirming that the integrity of climate alarmist scientists was indeed suspect. Science consequently had to swallow its pride and render the following editorial correction:

"Due to an editorial error, the original image associated with this Letter was not a photograph but a collage.

Monsoon Watch - 4

Forecasting Methods adopted for the Indian Monsoons:

Gowariker(1989) developed parametric and multiple power regression (MPR) models with 15 predictors for LRF of AISMR, which were later modified in 1991 to include 16 predictor parameters. The parametric model is qualitative and indicates the likelihood of the monsoon rainfall to be excess or deficient.

Thapliyal (1990) evaluated the relative performance of multiple regression, and Navone and Ceccatto (1994) have used 'feed-forward' neural network technique for the prediction of Indian monsoon rainfall with two predictors (500 hPa ridge location and Darwin SLP tendency from January to April). 

The results of a recent work by Krishna Kumar (1997) indicate that a single component accounts for about half of the total variance in the predictors

Most of the studies on LRF of Indian monsoon rainfall were based on empirical or statistical techniques till 2010. 
IITM, Pune has recently implemented the state-of-the-art coupled climate model, the Coupled Forecasting System (CFS) developed by the National Centers for Environmental Prediction (NCEP), USA. These statistical techniques range from simple correlation analysis to advanced procedures.

I still have faith, and believe in the "Gowariker Method" with 16 parameters. The results of this old but proven method has been successful. For Vagaries' forecast and analysis made in the "Arrival and quantum Monsoon Watch" series, I combine a few of them alongwith Dynamical models for a personal analysis and estimate. 

15 initial parameters from the months March, April and May are used to analysis and forecast the simulation of Indian monsoon rainfall during June to October. These initial conditions were carefully selected by experts to span the evolution of both the atmosphere and ocean.

Calculating the amount of rainfall, region wise, is of utmost importance, as SWM contributesto almost 80% of the annual total rainfall over India.
The performance of Vagaries' Monsoon Watch Quantum analysis is evaluated for the amount of summer monsoon rainfall over Indian monsoon region during June to SWM withdrawal.

The 500 hpa parameter is of importance in April. The mean latitudinal location of the 500 hPa ridge along 75°E in April over India, first identified by Banerjee (1978), is considered to be one of the most important predictors. The mid-tropospheric anticyclone over southern India migrates from 11.5°N in January to its northernmost position of 28.5°N during July. From October, the ridge starts shifting back southward. 
A more Northward location indicates better performance of the monsoon and vice versa. It also showed that the negative correlation of the March ridge was more dominant with the monsoon rainfall of the peninsular India, while the positive correlation of the April ridge was more dominant with the monsoon rainfall of Northern India.

ENSO factor in arriving at the rainfall amount is also of importance. The interface is the sea surface: that is where the transfers of water (evaporation/precipitation) and momentum occur. An accurate coupling of the fast atmosphere to the slow ocean is essential to simulate the ENSO, which in turn can simulate the interannual variability of Indian monsoon. Unfortunately, getting an accurate, or near to accurate forecast of the ENSO for the next 2 months is difficult, with no guarantee of accuracy or performance surety.

We see neutral conditions now. But, there is a possibility of a mild El-Nino event occuring as early as June/July. Now, this would result in "severe" break Monsoon condition in July. That is the last thing we want. But I would not endorse the event as yet. I would give it a 50-50 chance.

Limited pulses from the Eastern Pacific area, that is S.China sea, would mean lesser depressions and systems originating from the Bay. 
'In Situ" systems and systems from the Far east would contribute to the rainfall to the East Coast thru Central India and into Gujarat and even into Sindh (Pakistan).
El-Nino, even a mild one, would sort of restrict these pulses, and in fact encourage WDs into coming down South, more South than normal. 
But, for this, we would have to hope and pray for the Neutral ENSO conditions (presently on) to prevail and hang on till September. Again, a 50-50 chance for Neutral conditions.

Regarding the IOD parameter, recent forecasts from a few  coupled models  suggest  the possibility of development of a weak negative Indian Ocean Dipole event after July 2012.

1. Seasonal Low: Indicator: -ve

The heat is about to pick up in the Rajasthan/Sindh regions from the 3rd/4th of May, so good chance for the seasonal low to form and establish itself, at least by the 10th.Today the pressure at MSL is 1000 mb, with the core at 1000 mb. 
The sub Continent hot spots have just about touched the 44c mark (it is already Late. Refer MW-1) and should head for the 50c mark by around 16th May.

2. ITCZ: Indicator: Normal
As it is by the 10th, that we should have the ITCZ nearing the Equator. Only then would the Bay branch of the SWM could commence in the Southern Bay by the 15th of May.

3. Jet Streams: Indicator:-ve

These are streaming away in a Westerly direction above the 25N line. They are just about getting Easterly around 5N. Needs a rapid change now.

4. Cross Equatorial Winds: Indicator: Normal in Bay Branch. -ve in Arabian Sea Branch

Well established in the Bay region. SW winds, with sufficient speed hitting the S.Myanmar coasts, covering the Bay Islands with 20-30 knts, and could hearald the arrival of the SWM on time there.

Arabian Sea winds are now picking up, and rubbing the Somali coast at sufficient speed in getting the "Somali Current" established. The SST off the Somali Coast is 22c, While the required SST in First week June is 17/18c. (Required to form masses of Monsoon clouds in the warm central Arabian Sea).

Very Briefly, explaining the Factors considered for Seasonal Forecast:

If we take into account, that the ENSO will be Neutral, but "leaning" towards a weakish El-Nino phase by, say, end August, then:

a) There will be a drop in the systems originating from the Bay. If at all there will be weak depressions just about reaching Central India and fizzling out. 
Hence could result in rainfall deficit for the NW regions, including lower Sindh in Pakistan. Central India and adjoining areas will be well covered.

b) In such a scenario, even the 200 hps jet streams would bend slightly Southwards, and the "low" at that level will be dislodged. could bring in the odd WD even in July. Could bring some heavy rainfall to Upper Pakistan regions. Hence, rainfall could be normal/excess in rest Northern Pakistan and Kashmir. Though technically they will be Monsoon rains.

c) Due to systems reluctant to track southwards, we may see lesser rains in the Southern Peninsula regions. Even the support to the west coast (South of Mumbai)may be lesser than normal. Hence, rain shadow regions in TN and interior Karnataka may be slightly deficient. Lesser gradient along the West coast will show lower rainfall in Kerala, specially in June.

d) Break monsoon situations, and winds bringing in moisture from the Bay (diverted to the NW directions) will result in excessive rainfall this season in Nepal, more so the Eastern regions. NE states of India will get continuous feeding from the Bay. (Cherrapunji seems the likely candidate for the poll).

This is a very early estimates based absolutely on the situation as it shows and stands today.
