Abstract

The association between the onset of the monsoon and the subsequent rainfall distribution over three west coast subdivisions of India, viz., Kerala, coastal Karnataka and Konkan, has been examined for the 50-year period (1921–70). The results revealed that the rainfall received in these subdivisions during the early monsoon month of June and the monsoon season as a whole is independent of onset date.
