Eddy Generation in the Central Bay of Bengal
Eddies in the central Bay of Bengal are generated near the eastern boundary of the basin, related to equatorial wind forcing, nonlinearity, and the topographic “bump” of Myanmar.

Dispersal of River Water by Ocean Eddies and Shallow Ekman Flow
Low-salinity water from the Ganga-Brahmaputra river is transported by mesoscale eddies in the Bay of Bengal, but when the monsoon winds strengthen, a shallow “Ekman” flow dominates dispersal of water.
