The Pacific Ocean

The Mighty Pacific Ocean

Pacific Ocean is the largest ocean in the world. It covers nearly 28% of global surface and of course larger than the land area of the globe.  It stretches between Southern ocean in the Deep South, to Asia, Australia and to major portions of western hemisphere. The Sun shine over the Pacific and the clockwise (anticlockwise) sea gyrations in Northern (Southern) hemisphere Pacific have an impact over global weather. The western Pacific exhibits monsoonal winds and becomes the major cause for rainfall In Asia.  Similarly the heating of western Pacific influences the weather pattern in India.  The sea surface temperature anomaly and station level pressure anomaly in the region between 5o N to 5o S and 150o W to 120o W and more precisely between 160o E to 150o W have a dramatic impact on Summer Monsoon Rainfall in India.  This tele connection was first discovered by Sir Albert Walker.  Relatively strong intense heating in the far eastern portions of above mentioned region in Pacific Ocean during this April 2012 may play a dramatic role in Indian Summer Monsoon Rainfall [ISMR]. The delay in developing “Heat Low” in Thar Desert region and far west desert / continental area may be attributed to this effect. Hence monitoring of SOI and SST (NINO) anomaly in the above mentioned region will help in prediction of ISMR.

After last year's epic rainfall race for being the wettest places during South West Monsoon. I have compiled a poll for viewers and rain followers voting for the season 2012. The link to the polls is here Poll code. The 2011 rankings can be found here - 2011 SWM rainfall rankings
