Abstract

Along the west coast of the Indian Peninsula, north of lat. 9°N, rainfall during the monsoon season usually increases from the coastal boundary towards the Western Ghats. Monthly normal rainfalls (for July) of the different stations along the coastal belt, plotted against their distance from the sea coast, show a significant correlation (-0.6) with the distance of the 150-metre contour from the coast and appear to be uncorrelated with the distances of the 600 m and 900 m contours from the coast.  Apparently the gradient between the sea level and the 150-metre contour determines the magnitude of the coastal convergence, and the consequential vertical motion responsible for the rain.
