摘要
将“６３·８暴雨”与“７５·８暴雨”的天气学特征作了系统的对比分析。研究表明：尽管这两次暴雨相隔１２年，主要暴雨落区相距５００ｋｍ以上，发生暴雨的低气压系统分别来自西南与东南等差别，而形成暴雨的基本天气学过程是非常相似的。概括这两次暴雨的环流特征，提出了一种盛夏出现在中国北方的超强区域性持续暴雨天气的概念模型。
The comparison-analysis between' 1963. 8 rain storm' and '1975. 8 rain storm' is made. Itis shown,though there are some differences between the two cases of rain storms,such as there istwelve years interval,the distance between mean hyetal regions of them is more than 500km andone of their convergence systems from SW,another from SE; but the basic weather process forthese two rain storms are very similar. The circulation characteristics for the two rain storms maysummarized as a conception model for the regional continued super rain storm during midsummerin North China.
