| 摘 要： | 对40多年来南方的天气气候特征进行了分析,提出了7～9月夏秋干旱期形成干旱的主要天气系统为西太平洋副热带高压.从干燥度和降水的空间分布综合分析,得出了南方最旱区位于湖南、江西中部.广西、贵州、湖南西北和东南山区、江西南部山区、安徽南部山区、福建-浙江沿海交界山区和苏北沿海为湿润区,人工增雨潜力较大.特殊地形所形成的焚风效应是形成湘中干旱不可忽略的原因.为南方夏秋期间对流云降水潜力研究和科学实施人工增雨作业提供一定依据.

| Abstract: | The weather and climatic characteristics for 40 years in Southern China are analyzed. The results indicate that the West Pacific subtropical high is the main synoptic system caused droughts from July to September. The analysis of the aridity and spatial distribution of precipitation shows that Hunan Province and the central part of Jiangxi Province are the most severe drought areas in Southern China and Guangxi, Guizhou, mountainous areas in the northwestern and southeastern Hunan, mountainous areas in the southern Jiangxi, mountainous areas in the southern Anhui, inshore mountainous areas around the Fujian Zhejiang boundary and the northern Jiangsu inshore area are humid areas. These areas have relatively great potential for precipitation enhancement. The foehn effect resulted from the special terrain is a factor that cannot be negligible for droughts in central Hunan. Some scientific bases are provided for studying the potentials of convective cloud precipitation and for cloud seeding operation during the summer autumn period. |
