Abstract
Baaz cyclone is a slow moving weak cyclone in the south central Bay of Bengal (SCBoB) and it lingered for 3 days and caused a significant cooling (2.6 °C) and enhancement of chlorophyll-a (5.6 mg/m3) at the right side of the cyclone track. In this study multi-satellite observations are used to explore the bio-physical changes due to the cyclone. We found that the speed of the Ekman pumping velocity is ten times more and the mixed layer is deepened about 19 meters during the cyclone than pre cyclone period. The maximum sea surface cooling (1.2-2.6 °C) took place when the translation speed of cyclone is only 1.2-2.3 m/s. So the extent of the sea surface temperature drop is probably related to the moving speed of cyclone and the mixed layer depth. In addition, the area with large decline of the SSH can signify the location where the maximum cooling occurs.
