Weather Forecasting: Numerical Weather Prediction.

Most industrialized nations use numerical weather prediction (NWP) techniques to formulate weather forecasts. NWP is based on physical laws that are incorporated into a mathematical model, with solutions determined using computer algorithms. Large amounts of data are used to initialize the numerical models and verification of short-range NWP models shows a considerable improvement over climatology. NWP models require large mainframe supercomputers to formulate each forecast.
