Research on Winter Precipitation Types' Discrimination Criterion in Eastern China

中文摘要英文摘要

基于中国东部5个冬季的地面降水观测和高空探测资料,针对不同的降水相态,对它们对应的不同温度及不同厚度进行统计分析,最终得到一组中国东部地区冬季降水相态的推荐识别判据。分析发现:由于气候背景不同,我国东部的识别判据阈值和西欧的略有差别,而北美洲识别判据在我国东部的适用性也不好;综合考虑温度因子和厚度因子的识别判据表现则更好一些。该组判据对雨和雪的判别性能较好,TS评分分别达到0.91和0.73;对雨夹雪的容忍性判别TS评分也能达到0.57;但对冻雨…查看全部>>

Based on 5 years' surface observation and sounding data in eastern China Region,a set of discrimination criterion is suggested after statistically analyzing temperature and thickness for different precipitation types.It is found that:Discrimination criterion in eastern China is different from that of western Europe because of climate factors;Applicability of North America's criterion is not good to eastern China; Criterion combining temperature with thicknes…查看全部>>
