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.
