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

If a dry mountain has two slope, the one is warm facing - that receives more rain, other is rain shadow - that receives less or no rainfall. Concept: As the cloud ascend the mountain slope (2) Leeward side does not receive rainfall due to orography (3) The strain that windward side receives orographic rainfall due to dried hitting of water lacked wind & cloud
