(I) Onshore winds side up the hill from windward side
Rain Shadow Effect
(II) Warm air getting cold and condensed
(III) Precipitation on the windward side and hill top.
(IV) Exhaustion of moisture for leeward side creating rain shadow areas.
Distribution of precipitation across mountain regions
[Table showing Region, Mountain Range, and Effect on precipitation]
Region | Mountain Range | Effect on precipitation
(I) North America | Rockies Mountains | Creation of Rain shadow area in leeward side (East of Rockies)
(II) South America | Andes Mountains | Formation of Atacama Desert due to lack of Rainfall
(III) Asia :- | Western Ghats and Eastern Ghats | Creation of Rain shadow region in Tamil Nadu, Telangana region
(IV) Asia | Himalayas | Creation of Rain shadow (leas of persistent drying but rainfall monsoon)
(V) Africa | [illegible] | formation of temperate conifuge forest
These, rain shadow effect has been influential factor in shaping vegetation and precipitation in the region.
Conclusion
These, rain shadow effect has been influential factor in shaping vegetation and precipitation in the region.
