Orographic rainfall occurs in the mountainous regions near the coastal lines in general. Conditions favoring orographic rainfall in India is seen only over the Western ghats during monsoon period. Monsoon winds from Arabian sea gets blocked by Western ghats and gets lifted over the ranges and precipitates leaving dry winds to blow over Peninsular India.
Orographic rainfall results in heavier rainfall along the western side of Western ghats leading to more than 250cm rainfall per year.
Similarly Himalayas blocks the monsoon winds and precipitates rain over the ranges of Himalayas. Cherrapunji and Mawsynram are the wettest place in the world due to its location in the windward side of Himalayas and Tibet remains dry being in the leeward side.
During winter, Western Himalayas block the warm moist air from Mediterranean sea and results in orographic precipitation. This results in snow over the higher reaches of Himalayas in Himachal and Jammu and Kashmir.
Hence the average annual rainfall over India is more where the places receive orogarphic rainfall but the spatial distribution is not much!
