On the nature of meandering of the springtime western boundary current in the Bay of Bengal
Gangopadhyay, A.; BharatRaj, G.N.; Chaudhuri, A.H.; Babu, M.T.; Sengupta, D. (American Geophysical Union, 2013)We present evidence that the springtime western boundary current (WBC) in the Bay of Bengal is a continuous northward-flowing current from about 12 degrees N to 17 degrees N, which then separates from the coast at around ... -
