Numerical Weather Prediction Techniques

Numerical Weather Prediction (NWP) technique uses mathematical models of the atmosphere to predict weather based on current conditions. During the last two decades, weather forecasting all over the world has greatly benefited from NWP models. Significant improvement in accuracy and reliability of NWP products has been driven by sophisticated numerical techniques (advanced data assimilation algorithms, new observation systems, improved modeling techniques, physical parameterisations, advancements in computing power allowing for higher spatial resolution) and by the phenomenal increase in satellite observations....
