Give reasons:

Chennai has more rainy months but receives less rainfall than Mangalore.

Chennai lies on the eastern side of the Indian peninsula and receives rainfall both from the Southwest monsoon and northeast monsoon winds. Hence, it has more rainy months. But, the South west monsoon winds blow parallel to the Chennai coast and do not cause much rainfall. Mangalore lies on the windward side of the Western Ghats and hence, it receives more rainfall than Chennai inspite of having less rainy months.
