Recent observations of surface meteorology and exchanges heat, freshwater, momentum between the ocean atmosphere in Bay Bengal are presented.These characterize air-sea interaction at 18°N, 89.5°E from December 2014 to January 2016 also other locations northern Bengal.Monsoonal variability dominated records, with winds northeast summer southwest winter.This included a strong annual cycle atmospheric forcing Bengal, winter monsoon marked by sustained heat loss resulting cooling, storm events dark skies rain that resulted cooling.The spring intermonsoon was period clear low winds, when solar heating weak wind-driven mixing led warming.The fall transitional period, some but enough sunlight temperature rose again.Mooring shipboard used examine ability model-based fluxes represent Bengal; have significant errors.The observed 18°N is together one-dimensional model illustrate potential for local drive upper-ocean Bengal. Air-Sea Interaction BengalOceanography | Vol.29, No.2 we first summarize our observational methods, which include mooring deployed 13 months longer-running deployment moorings along 90°E
