Estimation of Salt and Fresh Water Transports in the Bay of Bengal

In the Indian Ocean, on annual time scales, there is a considerable exchange of salt and freshwater transports from Bay of Bengal BoB to the Arabian Sea AS and vice versa, and the paths of the highlow salinity waters are still speculative only. An important view of the pathways is the advection of low salinity waters from the BoB to the Southeastern Arabian Sea via the coastal Kelvin waves. The goal of this project is i to determine the propagation in the variability of coastally trapped Kelvin waves in the northern Indian Ocean, to establish pathways of fresh and salt water transports through the BoB to the AS, and to understand the impact of salinity on tropical cyclogenesis in the BoB ii Pathways of fresh and salt water transport are investigated in the BoB and throughout the Indian Ocean.
