Cyclone Persuade on Chlorophyll-A Enrichment in the Bay of Bengal

Abstract

The response of phytoplankton chlorophyll generated by two cyclones with different intensities in the Bay of Bengal during pre monsoon season (May) during 2003-2004 was studied by multi satellite approach. Chlorophyll-a (Chl-a) concentration (0.5 mg/m 3) increased with preceded by cooling (3.8°C) at the right ride of the track after the passage of cyclones. This is mainly due to the nutrient increase from vertical mixing and upwelling. The Chl-a enrichment is more during cyclone 01B compared with cyclone 02B, because of their intensities and movement.
