Simple 2D simulation of the Phailin Cyclone

It was the time of Dashain festival here at Nepal in 2013, which falls during the autumn season. The rainy season was supposed to have ended by then, but it had been raining for a couple of days and it was mainly because of the Tropical Cyclone Phailin that had hit the south eastern coast of India. No, the cyclone didn't reach Nepal, but it did send clouds here.

Here is my simplified 2D simulation of the Phailin Cyclone I did using the instantaneous vorticity data as initial condition. I mainly solve the 2D Navier-Stokes equation using a forth order finite difference scheme in MATLAB.
