In this paper, choosing two locations viz., Thiruvananthapuram and Mumbai, an attempt has been made to find whether the onset date of monsoon has any bearing on monsoon rainfall over Kerala and Konkan respectively. Association of the onset dates with Indian Summer Monsoon Rainfall (ISMR) for the country as a whole has also been explored. The study utilizes 100 years’ (1901-2000) data.
Homogeneity of the data and other rainfall features have been examined with the help of analysis. Frequency of simultaneous occurrence of droughts and meteorological floods at Kerala and Konkan have been determined and examined.
The study showed that onset over Thiruvananthapuram and Mumbai are significantly related. It revealed absence of any significant relationship between onset over Thiruvananthapuram or Mumbai and the ISMR. Meteorological floods seem to be more frequent over Konkan compared to Kerala.
