A STUDY ON TROPICAL CYCLONES OF THE ARABIAN SEA IN JUNE 2007 AND THEIR CONNECTION WITH SEA SURFACE TEMPERATURE

Khurrum Waqas Haider, Ghulam Rasul, Muhammad Afzaal

Abstract


The purpose of this study was to analyze the sea surface temperature of Arabian Sea and its correlation with the intensification of tropical cyclones. Advanced Very High Resolution Radiometer (AVHRR) satellite driven SST dataset of 0.25 degree horizontal resolution is used in this study. Forecast fields of a high-resolution regional model (HRM) have also been incorporated. An attempt was also made to analyze the possibility of predicting the SST for the month of June taking into account its teleconnection with El Nino Southern Oscillation (ENSO) index into account. The results showed that the average SST of Arabian Sea for the month of June during the period 1985-2007 is increased slightly while that of the Bay of Bengal is showing opposite trend. The SO index for the month of February does show a good correlation with SST of June but the correlation is not highly encouraging to be used as a prediction tool.
