Various numerical weather prediction (NWP) techniques are used for the prediction of tropical cyclones (TC) over the northern Indian Ocean (NIO). The article describes an objective NWP based cyclone prediction system (CPS) used for operational cyclone forecasting over the NIO.
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....
