Question

Comment on the rainfall occurring in the rain shadow area.

Answer 1

• The winds coming from lakes or seas are moisture-laden and they are obstructed by the high mountain ranges coming in their way
• They start going upwards along the slope of the moutains. The temperature of these winds drop and condensation occurs and rainfall takes place.
• This rainfall takes place because of the obstruction of the mountains which results in the condensation of water vapour.
• The windward side of the mountain gets more rain; the amount of vapour in the air reduces after crossing the mountain and the moisture-holding capacity of the air increases.
• The leeward side of the mountain gets lesser rainfall as compared to windward side.
• Thus, the leeward side area is identified as rain shadow area as it recieves meagre rainfall.
