Abstract: This paper introduces the flood of the Yangtze River in the midsummer of 1860 and the abnormal climatic phenomena of extensive areas,long period,low temperature and cold weather before rainstorm. On the 18th of July,1860,at Yichang hydrological station of the upper reaches occured the 92,500 cubic metres per second peak discharge,which was the fifth high since 1153.According to historical documents and carving records on walls,the flood was divided into three periods:rising period,peak period and dropping period;the progress of flood formation and three peak figures during peak flood period recorded in the publication“Dong Hu Xian Zhi”were introduced and described. In early May,1860,there were some striking abnormal climatic phenomena such as snowing extensively and low temperature lasted for a long time in the middle and lower reaches of the Yangtze River,raining in some local regions in automn after rainstorm in midsummer,early snowing in winter,and exceptionally serious flood.The author describes the relation between low temperature and cold weather before the early May,and rainstorm and flood in midsummer,from the aspects of climate-earth and earth-climate,and also considers that the former in the occurence process of the latter,and it is the forewarning phenomena reflected by the earth surface. As mentioned above,at the Yangtze River region in 1860,there were continuous low temperature and cold weather,much more precipitation,and continuous and frequent catastrophic rainstorm;all these were scarcely recorded on historical flood documents.
