  Tropical Indian Ocean temperature plays a vital on Indian monsoon system and also cyclone genesis. The feature and evolution mechanisms of the tropical Indian Ocean temperature between pre warming and warming period and also during Indian Ocean Dipole (IOD) events that co-occurred with El Niño are studied using Simple Ocean Data Assimilation (SODA) data set. The southeastern Arabian Sea, Western Arabian Sea and Seychelles Chaogos Thermocline Ridge regions subsurface temperature anomalies are cooled and the southern gyre, south Bay of Bengal, off java regions show warming trend from surface to subsurface. During the positive IOD with co-occurred El Nino years in a climate change period (1970-2008) surface warm temperatures are extended from the Sumatra region to off the African coast in pre-monsoon season. But the subsurface temperature shows different pattern, the warming is mo.. View More»
