Simulation of internal waves in the western Bay of Bengal using MITGCM: A case study

MITgem model is adopted probably first time for the western shelf region of the Bay of Bengal to model internal waves. Monthly climatological wind and density fields are considered in the model with real-time tides to generate internal waves in the region. The model simulations are compared with the actual observations available during 19-21 February 2012. Time series temperature data is collected at two locations off Gopalpur and is used to study internal wave characteristics. Thermal oscillations and energy spectra are studied and compared at the observed locations. It is found that internal waves of semi-diurnal nature are predominant over this region.
