A comparison of the areal raindepths from severe rainstorms in India with those of the world

摘要

This paper provides information on the largest areal raindepths for 1 to 3 days durations from severe rainstorms in India, Australia, China & the United States of America. The rainstorm of July 1941 caused by a Bay of Bengal depression produced the largest areal raindepths for 1 to 3 days durations in India. The areal rainfall comparison studies showed that for 1 day duration the areal raindepths from the My 1941 rainstorm in India are higher in magnitude than those for Australia and China. However, the Indian values are remarkably comparable with those of the USA for areas less than 1000 km~2 but for areas from 2000 to 5000 km~2 the Indian values are somewhat low. For the 2 and 3 days durations are concerned the areal rainfall values of India are higher in magnitude than those of China and the USA for areas from 10 to 50000 km~2 and of Australia for areas from 500 to 50000 km~2 for 2 days and from 2000 to 50000 km~2 for 3 days. It can be said that the July 1941 rainstorm of the Indian region is the most severe rainstorm of the world.
