studies like cyclone and monsoon predictions<\/strong>&nbsp;and ocean heat transport estimations.<\/li>\n\n\n\n<li><strong>Sea surface temperature (SST)<\/strong>&nbsp;is routinely used for predicting whether the total amount of rainfall that India receives during the monsoon season will be less or more than the long-term mean of 887.5 mm.<\/li>\n\n\n\n<li>Now, scientists from Pune\u2019s<strong>&nbsp;Indian Institute of Tropical Meteorology (IITM)<\/strong>&nbsp;find that&nbsp;<strong>ocean means temperature (OMT) that has a better ability to predict this than the sea surface temperature.<\/strong><\/li>\n\n\n\n<li><strong>Compared with SST which has a 60% success rate<\/strong>&nbsp;of predicting the Indian summer monsoon,<strong>&nbsp;OMT has an 80% success rate<\/strong>.&nbsp;&nbsp;<\/li>\n\n\n\n<li>The&nbsp;<strong>SST is restricted to a few millimeters of the top ocean layer<\/strong>&nbsp;and is largely influenced by strong winds, evaporation, or thick clouds.<\/li>\n\n\n\n<li>In contrast,&nbsp;<strong>OMT, which is measured up to a depth of 26 degrees isotherm<\/strong>,<strong>&nbsp;is more stable and consistent, and the spatial spread is also less.<\/strong><\/li>\n\n\n\n<li>The&nbsp;<strong>26 degrees&nbsp;isotherm<\/strong>&nbsp;is seen at depths&nbsp;<strong>varying from 50\u2013100 meters<\/strong>.<\/li>\n\n\n\n<li><strong>During January\u2013March, the mean 26 degrees C isotherm depth in the Southwestern Indian Ocean is 59 meters<\/strong>.&nbsp;<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter
