How silly can Greenpeace get? Imagine appealing to Dr. ManMohan Singh to save our Monsoons!!








The year 2009-10, India suffered its worst drought in almost four decades, with monsoon rains 22% below average. As seen in the the photo, Greenpeace activists hung an 80-foot banner from the Mumbai-Thane Bridge addressed to the Indian prime minister on June 4, 2009.It requested him to save our monsoons given the drought situation. How mischievous this tactic is illustrated by their article 29th June 2009, titled “It’s anomaly reigning” posted 29th June 2009 in their website - just a few days after this stunt:

“On assessing the historical data, the Intergovernmental Panel on Climate Change in its fourth Assessment Report suggested, “warming in India is likely to be above the average for South Asia, with an increase in summer precipitation and an increase in the frequency of intense precipitation in some parts.” That the Indian monsoons are going to undergo gross changes as a direct result of climate change – rainfall will increase by ~ 20 per cent overall in the summer monsoon, but the distribution of this increase will not be evenly spread across the country.”

So what's Greenpeace's actual position any way? Does global warming cause increased or decreased rainfall? But it does not matter really as global warming or CO2 has nothing to do with monsoon intensity. But it finds a strong correlation with ENSO

6pm, Heavy showers all along S-E coast... N-E Andhra, Orissa, Showers again over central, S. central & N. Tamilnadu.. http://ow.ly/i/3MNB
Chennai - After a sharp shower at around 4:30pm.. now 6:43pm... its mild at 26.7 C

"There's lots of commotion in the ocean." That saying was never more true than the current situation in the busy Atlantic Ocean.
The GOES-13 satellite captured this image on Tuesday Aug. 31, and visible are three areas of tropical commotion. The large and powerful Hurricane Earl (lower left) is passing Puerto Rico, Tropical Storm Fiona located to Earl's east, and Tropical Storm Danielle far in the Northern Atlantic.

Weather:
Very heavy rains in North Rajasthan and Haryana/Punjab today.
Reason ? Here is the Thai map with the explanation. The monsoon axis, shifts North, and the western end, a low at 998 mb sucks in and draws in all the moisture from the erstwhile system in the North Arabian Sea.The satellite image shows the clouds in that direction.
And rainfall along the axis, as always.(also seen in satellite image).
For west Rajasthan, I feel this could be the final bout of rains this monsoon.

I do not expect the moisture in these Northern regions to last beyond a day, with heavy rains in Delhi on Sunday.
But due to the monsoon axis being a bit North, some rains along the Delhi/U.P./Jh
arkhand belt c
ould continue till Monday.
From Tuesday, we can expect the axis to shift southwards along the South Rajasthan/M.P./Orissa line.


Weak rainfall will continue alng the west coast.
The states of Gujarat, M.P, interior Mah, interior Karnataka, A.P, and T.N. will have very
scaterred rains till Wednesday, 15th.

A request to re-read yesterday's blog on th forthcoming estimated low....
I expect a Bay low off the A.P. coast around the 15th. As of now, since the axis could fall in line of the low, the system should track into M.P.from the 17th.
More of this next week.

For Sep, Oct and Nov-2010... above normal showers forecast for Central, N.central and Western India... http://ow.ly/i/3KWl
Rainfall forecast for New Delhi during the start of Common wealth Games... http://ow.ly/2CG5l
RIGC seem to suggest wet weather for the National Capital Region in October, posing a threat to the smooth conduct of Commonwealth Games.

Monsoon may extend well into next month


Japanese researchers have maintained the outlook for prevailing strong La Nina conditions to reach a peak during the following winter.
The La Nina would be long-lasting and could persist until early 2012, according to Dr Jing-Jia Luo, Senior Scientist at the Climate Variation Predictability and Applicability Research Programme at Tokyo's Research Institute for Global Change (RIGC).

October rains
RIGC is latter-day incarnation of the erstwhile Frontier Research Center for Global Change under the Japan Agency for Marine-Earth Science and Technology (Jamstec).
Giving a month-wise break-up for expected rainfall in India, the RIGC said that the country as a whole, except extreme Southwest Coast, could witness an ‘extended monsoon' into October marked by above normal precipitation.
Extended outlook by the RIGC also would seem to suggest wet weather for the National Capital Region going into October, posing a threat to the smooth conduct of the impending Commonwealth Games.
The La Nina would bring above normal rains to Eastern Asia, Indonesia, northern parts of South America, Australia, besides India, during the autumn.

Cooler winter
The winter would see cooler than normal temperatures for most parts of India, Dr Jing-Jia informed Business Line.
Surface air temperature over many parts of the globe would be below normal. Exceptions could likely be the Northern Eurasian continent, Korea-Japan and Southeastern parts of North America.
South Africa, Australia, and Northeastern Brazil would have a cooler and flooding austral (southern hemisphere) summer during this period.
October rains are shown to be particularly heavier over the Southeast Coast and adjoining Interior Peninsula, parts of Central India and East India.
Even Northwest India could see slightly above normal precipitation (brought about mainly by western disturbances).
The month of November could, however, see a recess over North and Northwest India.
