Surface circulation and temperature inversions in the western Bay of Bengal using MITgcm
Himansu K Pradhan, A. D. Rao, Sachiko Mohanty
Abstract :
The sea surface circulation and the vertical temperature structure along the east coast of India is studied
using a 3D numerical model, Massachusetts Institute of Technology general circulation model. This model
is configured for the western continental shelf of the Bay of Bengal with bathymetry derived from Earth TOPOgraphy
datasets; temperature and salinity from World Ocean Atlas 2009; wind from satellite datasets. The simulations for premonsoon, summer monsoon and winter monsoon are studied in detail. The northward flowing western boundary current and southward flowing east India coastal current is captured very well by the model simulations and compared
with the observed OSCAR currents. The simulated temperature inversions during the winter months is compared with
observed ARGO datasets off Paradeep and Visakhapatnam and is found to be nearly 2oC.
