Prolonged Dry Spellsat Bellary During the Southwest Monsoon Season

Abstract

The daily rainfall data recorded at the Meteorological observatory, Bellary for the years 1921·1970 was analysed to study the dry spells during the southwest monsoon season. The chances of getting a prolonged dry spell seems to be the same throughout the Southwest monsoon seasons though the average rainfall during the months of August and September is almost double the average rainfall during the months of June and July. A prolonged dry spell of a tleast 30 days during the southwest monsoon is found to occur once in five years. In general, the probability for a dry spell of 'R' days to continue for atleast one more day is found to be greater than the random probability of getting a dry day as such during the southwest monsoon season.
