ABSTRACT :

Sea Surface Temperature (SST) is playing a vital role in convection and wind which transports the moisture. In this study, we have taken different grids over equatorial Indian Ocean SST and found that central Indian Ocean plays a crucial role for the advent of monsoon. At the same time check the relation between central Arabian Sea SST and the central Indian Ocean SST. However, Indian Ocean Dipole is also having effect on Indian summer monsoon. The winds which are coming from the southern hemisphere carrying moisture to Indian sub-continent through Arabian Sea having an effect of central Indian Ocean SSTs. Intensities of Zonal component is higher during the monsoon period and also both the regions showing relation, which is leading to precipitation over Indian sub-continent. However the intensities are varying with the El Nino and IOD. In this article we discussed and presented (about) the variations in SST and wind over central Indian Ocean and central Arabian Sea in relation to Indian summer monsoon rainfall.
