The Advance of Operational Numerical Weather Prediction in National Meteorological Center

Obvious progress has been made in the NWP of the National Meteorological Center in resent 15 years.The numerical prediction models were developed from a Northern hemisphere model to global spectrum model with a data assimilation system and a limited area model for precipitation forecasting. The prediction models for heavy rain and typhoon track are under development.At present,the valid time of the operational NWP has extended up to 7 days. The skill of present model T63's 96 hours prediction is better than that of the 48 hours prediction five years ago.The applied technology of NWP has been developing continuously.
