中文摘要: 在最近的15年中,国家气象中心的数值预报业务高速度发展。预报模式从北半球模式发展为全球谱模式,并配套建立了资料同化系统和用于降水预报的有限区预报模式,暴雨和台风预报模式正在研制中。目前数值预报时效已延至7天,T6396小时的预报水平已优于5年前48小时数值预报结果。数值预报产品的应用技术在不断改进,最高(低)气温两天MOS预报精度已接近预报员制作的综合预报结果。
中文关键词: 数值预报模式，资料同化，业务系统，产品应用
Abstract: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.
