There is a general belief that in the monsoon season (June to September) if more cyclonic disturbances, such as depressions, deep depressions and storms, traverse the country, more rainfall will be received in that season. In order to investigate this the statistics of cyclonic disturbances traversing the land area of the country during the 60-year period from 1901 to 1960 has been examined. Monsoon season rainfall of the country as a whole has also been worked out for each year of the 60-year period using the data of more than 3,000 rainfall stations distributed uniformly over the country. The study has shown that the number of these disturbances or the number of days spent by these disturbances in traversing the land area of the country during the monsoon season is not a reliable index of monsoon rainfall over the country.
