Study of Upwelling along the West Coast of India—A Climatological Approach

ABSTRACT Shah, P.; Sajeev, R., and Gopika, N., 2015. Study of upwelling along the west coast of India—A climatological approach. With extensive use of satellite-measured climatology, the present study investigated the upwelling along the entire west coast of India and authenticated the differences in upwelling along the SW and NW coasts. During May and September, the entire west coast of India was characterized by weak offshore surface mass transport. During June, July, and August, offshore surface mass transport was limited to SW coast of India, and onshore transport was observed along NW coast, except at 16° N and 17° N, where very weak offshore transport was observed, compared with SW coast. Analysis of the Sea Surface Height Anomaly, depth of 26° isotherms, and Local Temperature Anomaly revealed the role of remote forcing on the upwelling along the west coast of India, especially during the peak summer monsoon months. The observations on the Local Temperature Anomaly at different depth levels exposed ...
