T213模式对强冷空气短期预报能力的分析检验

Verification and Discussion of Prediction of the T213L31 Model on Short-range Forecast of Strong Cold Wave

利用T2 1 3模式的 50 0hPa高度、地面气压、850hPa温度预报格点资料和客观分析实况格点资料 ,对 2 0 0 1～ 2 0 0 2年冬半年我国出现的 8次强冷空气天气过程的主要影响天气系统进行了预报能力的客观分析检验。所得结果有利于数值预报产品的释用及实时预报业务。

Based on grid data of forecasting fields (500hPa height, sea level pressure, 850hPa temperature) of T213L31 model and real-time objective analysis fields, prediction Natures on main affecting synoptic systems of eight strong cold wave processes in China during 2001/2002 winter are verified. The result benefited the interpretation of NWP products and operational forecast.
