2002年夏季石家庄两类历史极端高温成因分析

运用常规资料，分析了石家庄2002年7月15日极端晴热高温和8月2日极端闷热高温天气的成因，分别受大陆暖高压和副热带高压暖气团控制是造成两类高温出现的根本原因。受地形影响，偏西风造成的焚风效应和高压后部偏南风造成的暖湿空气在山前积聚，分别加剧了两类高温的强度。强烈的太阳辐射也是造成极端晴热高温的一个重要原因。

Study of Two Extreme High Temperature Events During Summer 2002 in Shijiazhuang

By means of conventional meteorological data, the reason s of two extre me high temperature events (clear-and-hot high temperature weather occurred in 1 5 July 2002 and the extreme muggy high temperature weather occurred in 2 August 2002) are studied. The results show that they were controlled by the continental warm high and the subtropical warm high respectively over the western Pacific. Aff ected by topography, they were strengthened by the foehn effect caused by west w ind and the warm moisture accumulation before mountains caused by south wind. So lar radiation is also an important factor causing the extreme clear and hot high temperature event.
