我国是世界上多暴雨国家之一，而长江中下游地区又是我国大暴雨出现最为频繁的地区之一。暴雨，尤其是特大暴雨或连续性暴雨，往往是引起长江中下游大洪水的直接原因，因此，暴雨预报成为防洪渡汛的重要环节。在对长江中下游暴雨历史资料进行普查、分析的基础上就其降水特点、天气分析及预报方法等进行了较为系统、全面的概括。
China is one of the most stormy countries in the world, and the middle and lower reaches of the Yangtze River is one of the areas where the torrential rains occur most frequently in our country. Heavy rains, especially heavy rainstorms or continuous heavy rains, are often the direct causes of major floods in the middle and lower reaches of the Yangtze River.
