3D Modeling of Wind-Driven Circulation In The Northern Indian Ocean During Monsoon
Abstract:   (814 Views)
Abstract
The purpose of this research is to design and identify some of the natures and characteristics of high-resolution surface currents in the Northern Indian Ocean. The pattern of 3D circulation of the Wind-driven surface currents, Sea surface temperature (SST) and Sea Surface Salinity (SSS) distribution in the Northern Indian Ocean using The MIT general circulation model (MITgcm) with horizontal (2 arc-minutes) and vertical (20 Levels) resolutions during Monsoon was simulated and the model became stable after 17 years. This resolution is very accurate for the reproduction of ocean circulation and the eddy dynamics.Temperature, salinity, wind, net heat flux, evaporation minus precipitation as the initial data were introduced to the model. According to the results, an upwelling was characterized at 61°E-24°N near Chabahar in July, as well as a strong anticyclone take places at 56.5°E-18°N which enters to the north Arabian sea after a clockwise rotation. The summer monsoon current flows eastward during the summer monsoon (May-August) and the winter monsoon current flows westward during the winter monsoon (November-February) and also, the jet of Ras Al Hadd at the Oman coast is identifiable in the model.
Keywords: Monsoon Circulation, Ras al Hadd, SST, SSS, Northern Indian Ocean, MITgcm.
