Explain the concept of rain shadow effect. How does it influence the distribution of precipitation across mountain ranges?

Impact of Rain Shadow effect: A) On precipitation: (1) The windward side receives more rainfall (eg - Western post of western ghats) (2) The leeward side is often barren and drought prune (eg - Marathwada Region) (3) Many times the rain shadow side turns into desert (eg - Nubra Desert Ladakh) B) On Vegetation: (1) On the windward side dense and (4) The rain shadow side has less dense and thorny vegetation (eg - Cactus in Nubra Desert) Thus, rain shadow effect is defined by vegetation, physiography, agriculture and climate of the region.
