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.
