ANN based Data Mining Technique to Achieve Improved Accuracy to Predict ISMR from Ocean –Atmosphere State Variables

Oceans are currently undergoing a warming phase in response to global climate change. Rate of warming is however not uniform within a particular ocean and also between the oceans. Utilizing ICOADS Sea Surface Temperature (SST) data of 53 years (1960-2012), we studied the warming trend(s) in Indian Ocean (IO) on monthly, seasonal and annual scale applying statistical regression tools. Higher warming rate [0.300C/decade] has been identified in the equatorial IO. Over the tropical Indian Ocean, rate of warming had varied from 0.05 to 0.300C/decade. We also find that ICOADS data has limitations in producing the basin wide estimate of long term warming trend due to the limited data coverage.
