Abstract

Cherrapunjee and nearby Mawsynram (located 15 km away) receives the highest annual rainfall in the world. On the basis of annual, monthly and daily rainfall for the period 1980–2004 was made an attempt to show similarities and differences between the two sites. Analysis was supported by investigation of hourly course of rainfall at Cherrapunjee. The interaction between large-scale circulation and the local topography plays a crucial role in rainfall spatial distribution at Cherrapunjee and Mawsynram. Despite their close proximity, differences in annual rainfall can reach several thousand millimeters. Results has shown that mean annual rainfall totals are higher at Mawsynram, while the mean number of days with rainfall is higher at Cherrapunjee. In addition, the number of days with rainfall up to 50 mm is higher at Cherrapunjee, while the number of days with rainfall exceeding 100 mm is higher at Mawsynram. However, the rainfall distribution for the summer monsoon season as well as the precipitation concentration index at both sites are similar.
