¥Numerical Weather Prediction (NWP) - use
mathematical models
of physics principles to forecast
future state from current conditions.
¥Process
involves three major phases
1.Analysis Phase
(estimate present conditions)
2.Prediction Phase
(computer modeling)
3.Post-Processing
Phase (use of products)
¥To justify NWP cost, it must beat forecasts of persistence, trend, analog and
climatology
