基于神威中期集合数值预报系统的产品开发

THE DEVE LOPMENT OF ENSEMBLE PRODUCTS BASED ON THE SHENWEI MEDIUM-RANGE ENSEMBLE PREDICTION SYSTEM

摘要: 利用我国神威中期集合数值预报系统 32 个成员的输出资料, 根据预报业务的需要, 开发出新的集合预报产品。其产品有 500 hPa 高度场分簇和特征等高线面条图、关键点 850 hPa 温度的概率烟羽图和温度变化趋势图、全国省会城市的要素预报分布图。

Abstract: Based on 32 forecast members of the Shenwei Medium-Range Ensemble Prediction System and the need of operational forecast, some new ensemble products are developed. These products include the clusters of 500 hPa height trajectories, “spaghetti” charts of special 500 hPa height contours, probability “plumes” and ensemble mean charts of 850 hPa temperature, and weather element forecasts from provincial capitals of China.
