Special Issue: Bay of Bengal: From Monsoons to Mixing
On the Cover: A series of vignettes from a research ship in the Bay of Bengal (above water), during the southwest monsoon season. On sunny days, the sea surface is a source of heat and moisture feeding deep atmospheric convection. The placid conditions are abruptly terminated by an approaching wall cloud, accompanied by gusty winds and torrential monsoon rains. While the ocean’s surface layer is visibly stirred up, what are the processes that determine the interior properties and currents? And, how are the air-sea fluxes themselves affected? These are questions addressed by the articles in this issue. Photo credits: Above-water photographs by San Nguyen, Scripps Institution of Oceanography.
