| 摘 要： | 利用2006年新疆107个测站的实况降水资料和T213模式的降水预报值,根据中短期天气预报质量检验办法中客观降水检验方法,对T213数值降水预报产品的24 h预报能力进行了分析检验,结果表明：（1）T213对新疆地区暴雨和大暴雨基本无预报能力。（2）T213在新疆区域对于小量和中量降水的整体预报能力北疆要明显好于南疆。（3）T213的预报能力存在一定的季节性,对弱降水过程预报能力较差。（4）从小量到大量降水,T213的空报率和漏报率都很高,整体预报效果不好。

| Abstract: | Based on the objective rainfall verification method of the quality inspection methods for short-range and mid-range weather forecast, the 24-hour forecasting abilities of the precipitation forecast products of T213 were verified by using observational rainfall from 107 stations in 2006 and precipitation forecast values of T213 global model. The results show that: (1) The T213 model have poor ability in forecasting torrential rain in Xinjiang; (2) The forecasting ability of T213 model to light and moderate rain in northern Xinjiang is better than that in southern Xinjiang; (3) The forecasting ability of T213 is seasonal and have poor ability in weak precipitation processes; (4) From light rain to heavy rain using T213 to forecast, the rate of false alarm and dismissal are rather high, and forecast effect of T213 is not satisfactory generally in Xinjiang. |
