Assessment of Precipitation Prediction of T213 Model in Henan Province

对 2 0 0 2年 1 0月～ 2 0 0 3年 9月T2 1 3降水预报产品的预报效果进行了分型和分区检验 ,结果表明 :冬半年对小量级预报能力较强 ,夏半年对大雨以上量级的降水有较好的预报效果 ;东高西低型降水各量级的预报均有较高的准确率 ,低槽型次之 ;

Utilizing the meteorological data from October 2002 to September 2003, we examine the effect of T213 precipitation predict product. Results show that: It has a good effect to predict light rain/snow from October to next March and heavy rain from April to September; the precipitation prediction of east- high- and west- low- pressure is more accurate and less accurate for low Pressure pattern; the accuracy of the prediction is higher in South than in north for the most part.
