Parallel Implementation of Two Level Barotropic Models Applied to the Weather Prediction Problem

Forecasting model for short range weather prediction that is used here is the two level Barotropic models. This model is used because it can give approximation of air conditions covering higher isobar levels. By using finite difference approximation, quasigeostrophic vorticity equations and therm...
