Orographic Rainfall

Orographic Rainfall



Winds coming from lakes or seas are moisture laden. 

They are obstructed by high mountain ranges. They start going upward along the slope of the mountain. 

The temperature of these winds drops as they go higher causing condensation, resulting in the formation of Orographic clouds. The rain pouring from these clouds is called Orographic rainfall.

Windward side of mountain receives more rain, leeward receives less. The leeward side is also called the rainshadow region.


Watch the process of Orographic rainfall in the video above.

Cyclonic Rainfall

Image
Cyclonic Rainfall Cyclone is the specific air formation when the pressure at an area is less than the surrounding regions.  It is formed when two masses of air of different temperature , humidity , and density meet. Warm air and cool air do not mix as they have different densities. The warm air rises over the heavier cool air.  Warm air from the surrounding regions comes to the centre of the cyclone and starts moving upward.  As it rises, the temperature of the air reduces.  Then condensation occurs resulting in cyclonic rainfall.  They are cyclonic and stormy in nature .
