在暴雨频繁、范围广、强度大、洪水变幅大的地区,可能最大降水的研究,早已受到重视。我国位于副热带和北温带大陆东岸的季风气候区,地形复杂,海陆影响显著,是一个多暴雨的国家,尤多特大暴雨,24小时降水量接近或超过1,000毫米的暴雨已有5～6处之多。从历史暴雨洪水资料及由历史洪水估算的洪峰 In the frequent heavy rain, a wide range, intensity, floods large areas, the possibility of maximum precipitation research, has long been valued. China is located in the monsoon climate zone on the east coast of the subtropical and temperate North China continent with complicated terrain and significant land and sea impacts. It is a heavy rainstorm. In particular, there are 5 to 6 torrential rain with a rainfall of 24 hours and exceeding 1,000 mm many.
