摘要
通过对长治市1977年-2004年6月-8月出现≥35℃的高温天气的地理分布特征、时间和强度等统计研究，给出了高温天气的气候背景。从500hPa高空形势分析，归纳出造成高温天气的四种主要环流形势（两槽一脊型、纬向环流型、大陆暖高型、副高控制型）；分析了风、云、降水等气象要素与高温天气的内在联系。通过850hPa高温预报指标站的选取及数值预报产品的统计分析，给出了高温天气的综合性预报模型。
The climate background of high temperature weather is gotten based on statistical study of the geographic distribution characteristics, time and intensity of high temperature weather which temperature greater than or equal 35 ~C in Changzhi city in June August from 1977 to 2004. The four kinds of circulation patterns （two troughs and one ridge and zonal circulation patterns, continental warm, the subtropical high control） are summed up by the analysis of 500hPa altitude situation. The relationship between high temperature weather and wind, cloud and precipitation is analyzed. The prediction model of the high temperature weather is given based on the statistical analysis of the selection of 850hPa temperature forecast indicators station and the products of numerical forecast
