Some Aspects of Argentine Rainfall

Abstract

This report investigates at first what percentage of the number of days with rain accounts for most of the rainfall in widely separated climatic provinces of Argentina. It turns out that this percentage, which may be termed the relative precipitation intensity, is a constant in space and time. Then the frequency distribution of natural rainfall periods (rainstorms) is analysed in relation to the rainfall derived from these disturbances. It is found that the same percentage of the rainstorms accounts for the same large fraction of total rainfall regardless of season or geographical effects.
