Thermohaline features of the subsurface cyclonic eddy in the south central Bay of Bengal during August 1999

[摘要] Analysis of the spatial data collected along two sections of temperature and salinity from Chennai to 13°N and 87°E and back to Chennai onboard INS Sagardhwani during the Bay of Bengal Monsoon Experiment (BOBMEX) from 10th to 20th August 1999 revealed the presence of a prominent cyclonic eddy centered around 280km away from the coast. Analysis of the dissipation rate of the cyclonic eddy from transect one to transect two and from the analysis of the TOPEX data, it may be inferred that the cyclonic eddy is possibly due to the presence of westward propagating Rossby waves in the Bay of Bengal.
