The effect of the marine biogeochemical variability upon the South Asian regional climate has been investigated. In the experiment where its full impact is activated, the average sea surface temperature is lower over most of the ocean. When the biogeochemical coupling is included, the main impacts include the enhanced phytoplankton primary production, a shallower thermocline, decreased SST and water temperature in subsurface layers.
Our modeling approach has improved significantly (~30 % to 60 %) the simulation of North Indian Ocean tropical cyclones’ track and intensity. The results are promising. This technique can be used for real-time cyclone predictions over the study region to provide more accurate cyclone related warnings and alerts for better planning and preparedness.
