Abstract

Air-sea interaction plays a dominant role in modulating the ocean-atmospheric circulation pattern and in bringing about changes in global weather and climatic systems. In the present paper a one-dimensional multi-level numerical planetary boundary layer (PBL) model with a TKE-ε closure scheme was applied to simulate the air-sea interaction parameters over northern part of Bay of Bengal (Indian Ocean). The oceanographic research ship observed high-resolution sounding data comprising of the vertical profiles of temperature, humidity, zonal and meridional component of wind was used as initial and boundary conditions to integrate the model. The temporal evolution of turbulent kinetic energy (TKE), marine boundary layer (MBL) height, sensible and latent heat fluxes are simulated for the duration of study. The model simulated vertical profiles of potential temperature, specific humidity, zonal and meridional wind compare reasonably well with the observations.
