摘要
利用历史天气图资料，从大气环流特征角度对区域性干旱进行了分析，结果发现：本市区域性干旱的大气环流可分为——西太平洋副热带高压控制型，大陆高压型和东亚大槽稳定型。其中，西太平洋副热带高压控制型的夏旱最为严重。同时，本文对夏旱的短期气候预测进行了探讨。
Using the historical weather map information, the drought in Ninde was analysed on the feature of atmospheric circulation characteristic. The results showed that the atmospheric circulation pattern which cause drought in Ninde may be sorted into three type, the first is controlled by West Pacific Subtropical high, the second is stable mainland high, the third is stable East Asia trough. The first type usually causes the strongest summer drought. At the same time, the short-term climatic forecast of summer drought was discussed.
