Main Body
Causes of Atmospheric Rivers
-> Heavy evaporation leading to moisture laden air
-> Evaporation through Jet stream, trade wind & walker circulation.
-> Triggering of heavy downpour in low pressure areas.
Effect on global weather pattern
1Lead to change in local weather Eg -> precipitation in Atacama desert.
2It leads to cooling of climate due to precipitation.
3Role in water cycle, may recharge dried up ecosystem Eg -> dry californian forests.
4Disturbs walker circulation from part of earth to other.
5Effect on cyclones, may feed & intensify cyclones.
