中国东部地区冬季降水相态的识别判据研究OA北大核心CSCDCSTPCD
Research on Winter Precipitation Types＇ Discrimination Criterion in Eastern China
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>>
