Abstract

 Intra-seasonal variations during the summer monsoon have been documented by various workers. Recently, low frequency oscillations in the time scale of 10- 15 days and 30- 50 days have been extensively studied. The morphology of intra-seasonal fluctuations on a regional scale (over the Indian sub-continent) has been studied using mean circulation parameters. The low frequency oscillation (30- 50 days) an~ its contribution to the fluctuations of rainfall have been discussed. Synoptic scale (3 -5 days) oscillation and the quasi-biweekly oscillation appear more relevant as a tool of explanation f,-,r the major intra-seasonal oscillation in rainfall.
