The currents, sea surface temperature, and salinity patterns in the Bay of Bengal

Abstract

The Bay of Bengal is a semi-enclosed basin, with its southern side open to the Indian Ocean. Therefore, the current circulation is very influential in the condition of the ocean parameters. This study aims to examine the effect of current velocity on the distribution pattern of sea surface temperature (SST) and sea surface salinity (SSS) in February and August in 2017 in the Bay of Bengal. This study uses the results of Hybrid Coordinate Ocean Model (HYCOM) data for the main parameters, namely current, temperature and salinity which were analyzed with the calculation results of precipitation and evaporation data. The results of the data obtained in February showed the average current velocity conditions and low SST and relatively high SSS in the south. In August the average current velocity and SST is high and SSS is low. The results of the average data of low rainfall and relatively low evaporation are produced in February, the results of the average high rainfall and relatively high evaporation are produced in August. The resulting value gives the results of the relationship between current circulation and changes in parameter conditions in the waters.
