Major climatological discontinuities in the monthly monsoon activity in the neightbourhood of theWestern Ghats

The major climatological discontinuities to the monsoon activity from July to August and from August to September in the neighbourhood of the Western Ghats have been studied in detail on the basis of a close network of raingauge stations and the role of the Western Ghats has been examined, The criterion used for defining the major climatological discontinuity is based on the quartiles of the monthly rainfall distribution, The Western Ghats appear to playa differential role. Since meteorological conditions are most favourable during July and become progressively less favourable with the advance of the summer monsoon season, the Western Ghats enhance rainfall substantially under favourable conditions, and decrease the rainfall substantially under relatively urifavourable conditions, and thus contribute to the major climatological discontinuities.
