今年夏季,山西出现多次大范围高温天气过程.为定量化分析高温过程,本文构建山西省区域高温天气过程等级划分方法,并选取6月26日-7月4日、 7月7日-7月15日、7月17日-7月27日三次大范围高温天气过程进行定量评估分析,结果表明:6月26日-7月4日我省出现较强的高温过程,临汾、运城达到I级或Ⅱ级高温,其余地市均为Ⅳ级高温,全省区域范围为Ⅲ级高温;7月7日-7月15日我省出现强高温过程,太原、阳泉、临汾、运城达到I级高温,晋中、吕梁、晋城达到Ⅱ级高温,其余地市均为Ⅲ级高温,全省区域范围为Ⅱ级高温;7月17日-7月27日我省仍有较强高温过程,临汾、运城达到I级或Ⅱ级高温,太原、晋中、吕梁为Ⅲ级高温,其余地市为Ⅳ级高温,全省区域范围为Ⅲ级高温.实时评估结果可为旅游、电力、保险等相关产业提供决策依据.%This summer, there have been many large-scale hot weather processes in Shanxi. For quantitative analysis of high temperature process, this paper build the high temperature weather process hierarchy method of Shanxi Province.The three large-scale hot weather processes from June 26th to July 4th, July 7th to July 15th and July 17th to July 27th were selected for quantitative assessment and analysis. The results show that the high temperature process appeared in the province from June 26th to July 4th, and Linfen and Yuncheng reached grade I or II high temperature, the other cities were grade IV high temperature, and the area of the province was grade III high temperature; From July 7th to July 15th, the high temperature process appeared in our province, Taiyuan, Yangquan, Linfen and Yuncheng reached grade I high temperature, Jinzhong, Lvliang and Jincheng reached grade II high temperature, the rest of the city were grade III high temperature, the whole province was grade II high temperature. In July 17th to July 27th, our province still had strong high temperature process, Linfen and Yuncheng reached grade I. Or grade II high temperature, Taiyuan, Jinzhong and Lvliang are grade III high temperature, the rest of the city is grade IV high temperature, and the whole province is grade III high temperature. The real-time assessment results can provide decision-making basis for tourism, electricity, insurance and other related industries.
