Predicting the Weather and Natural Circulation

 

I

Numerical Weather Prediction (NWP) is a way to predict weather by calculation on the basis of physical principals (conservation of energy, momentum and mass) , and is a vital tool for modern meteorological services because of its high accuracy. JMA runs NWP models using a super computer to predict future atmospheric state. In that process, the computer first creates the initialized fields of such meteorological elements as atmospheric pressures, temperatures and winds, Synoptic stations, ships, aircraft and satellites are the major data sources to create the initial fields. Then the computer makes a time integration of dynamic equations from the initialized fields to produce future atmospheric state.
