| 摘 要： | 山西省在2006年雨季(7～8月)出现大范围的高温干旱,导致了严重的人畜饮水困难和农业灾害.尤其是在常年降水峰期(7月下旬至8月上旬),没有出现一场大范围强降雨天气过程,在历史上实属罕见.该文通过对500 hPa环流场、副热带高压特征量等资料的分析.揭示了山西2006年雨季气候异常的主要原因,主要包括冷空气的活动偏弱、副热带高压位置异常偏北,中低纬度天气系统的配合不到位、ENSO的形成及其影响等.

| Abstract: | By using the observation data from only three solar radiation stations in Guizhou Province, comparison is made between the calculation errors from two methods (sunlight percentage and nationwide universal formula). The results indicate that the absolute error values of the monthly and annual mean solar radiation calculated by the sunlight percentage method are less then 10%, and the sunlight percentage model is better than the universal method obviously. Since solar radiation increases with increasing altitude, the model is set up according to the altitude of each station by means of the sunlight percentage method. From the related data from 1971 to 2000, the solar radiation is calculated, and the distributional characteristic are analyzed. |
