The monsoon rain has certain characteristics which make it unique.

(a) Monsoon winds are unreliable, as the exact time of arrival and departure is not the same year after year.

(b) The rainfall is unevenly distributed. Certain areas receive heavy rainfall (windward slopes of the Western Ghats) while in other areas the rainfall is less (Thar Desert), causing floods and droughts.

(c) The monsoon rain is concentrated within the three months (June - September) of the year while the rest of the year is more or less dry.

(d) There is a seasonal reversal of winds.

The monsoon rains are important in India and its effect can be seen when they arrive. All over the country people eagerly wait for its arrival. The farmers are ready to sow their seeds and the agricultural activities begin. Water is provided to the rivers which carry it to different parts of the country. Plants and animals rejuvenate with the coming of the monsoons. The supply of water through rivers is very important for the generation of power.
