RS11A:
Ocean Circulation and Air-Sea Interaction in the Bay of Bengal I


Session ID#: 36721

Session Description:
The Bay of Bengal is a unique semi-enclosed tropical ocean basin forced by and coupled with the summer/winter South Asian Monsoons and fresh water inputs from some of the largest rivers in the world. This session aims to bring investigators together to characterize the Bay of Bengal ocean circulation at a range of spatial and time scales. Scales of interest are: spatial scales spanning basin-scale circulation to fine-scale dynamics (fronts, mixing) and time scales from diurnal, intra-seasonal, seasonal, inter-annual to decadal. Using observations, modeling, and theory, we aim to synthesize our understanding the ocean’s role in air-sea interactions and the Monsoons. Topics of interest include upper ocean processes, air-sea interaction, boundary currents, freshwater dispersal, and mixing in the Bay of Bengal and exchange with the Arabian Sea. We encourage presentations that characterize the upper ocean structure and identify key processes that set the lateral and vertical temperature-salinity distribution over a range of length and time scales. Processes that influence bio-optical and biogeochemical property distributions are also of interest. We welcome studies that focus on the coupling of the atmosphere and ocean, e.g., tropical instabilities, intra-seasonal oscillations, as well as those that detail factors controlling sea surface temperature and air-sea fluxes.
