Chennai - Going to have a cold night with mild stiff breeze... and early morning will be cold around 20 deg C
Severe cold wave conditions are prevailing at a isolated places over Punjab & Haryana, s. Rajasthan.
A feeble western disturbance would affect Western Himalayan Region during next 2 to 3 days
For next 3 days showers may linger along S, S-E Tamilnadu and over Srilanka.
Now there's a chance of a LOW over central bay and it's expected to move slightly N-E and then die over open sea.
Rain threat for Entire Tamilnadu coast has been removed... only some odd isolated showers possible.
Yesterday's cloud formation over S-W Bay near to C. Tamilnadu coast has moved away from land .. due to a S-W Upper air current steer.
According to UAH (satellite) data, 1998 (+0.424 deg. C) barely edged out 2010 (+0.411 deg. C), which suggests a whisker of a win for 1998. The margin 0.01 is not statistically significant but what is significant is that for the last 12 years, there is no evidence of accelerating global warming trend. There is of course an underlying warming trend since 1979, but it is not linear, and basically flatlined over the last 12 years.
If 2010 is one of the warmest in recorded, then 2011 is likely to be one of the coldest as evident from Dr Roy Spencer's comments:
“The following plot shows global average sea surface temperatures from the AMSR-E instrument over the lifetime of the Aqua satellite, through Dec 31, 2010. The SSTs at the end of December suggest that the tropospheric temperatures in the previous graph still have a ways to fall in the coming months to catch up to the ocean, which should now be approaching its coolest point if it follows the course of previous La Nina’s”
