2. Numerous Factors Contributed to Catastrophe

The 1931 China Floods began with a severe drought that hit China from 1928 to 1930. It was followed by an exceptionally severe winter in 1930, which deposited unusually massive amounts of snow and ice in the mountainous areas upstream from the Yangtze and Huai rivers. All that snow and ice melted early in the spring of 1931, and flowed downstream into the two rivers. It reached the middle Yangtze River Valley when the region was already experiencing exceptionally heavy spring rains. Things were made worse still by an unusually high number of cyclones. On average, the region experiences two cyclones a year. In 1931, it was hit by nine cyclones. All of those factors combined to bring about a catastrophe.
