摘要：

利用我国华北地区1961~2000年夏季6~8月高温资料,探讨了华北地区主要城市高温过程,建立该地区强高温过程较完整的序列。分析华北主要城市北京、天津、石家庄、济南、太原市等夏季危害性高温气候特征。给出了东亚副热带高压和大陆变性高压的活动特点。观测结果表明,东亚副热带高压和大陆变性高压对华北地区主要城市夏季危害性高温在各地有很大差异,与相对湿度大小有密切关系。东亚副热带高压和大陆变性高压的活动是造成华北地区城市夏季危害性高温的主要影响系统。在此基础上建立了华北主要城市夏季危害性高温候、旬、月评估方法。其结果表明该方法对华北地区主要城市夏季危害性高温影响评估有应用价值。

Abstract:

Based on the high temperature data covering June-August during summer of 1961-2000 in northern China, climatic characteristics of high temperature weather in Beijing, Jinan, Shijiazuang, Tianjin and Taiyuan are analyzed. Variable features of the subtropical high and denaturalization high are discussed. The results show that the subtropical high and denaturalization high over the high temperature weather in northern China are closely related with humidity. The subtropical high and denaturalization high in eastern China are the most important system. With an assessment model established, some computing cases show that the assessment experiment of the method has reference value to the assessment of the muggy high temperature weather in most cities of northern China.

Key words: northern China, high temperature of cities, climatic characteristics, assessment model
