$\rm{\huge{\boxed{\underline{Cyclonic\: Rainfall:-}}}}$

→️ This type of rainfall is associated with the passage of a cyclone or a depression.

→ The term cyclone is derived from the Greek word “Kyklon”, meaning “Revolving”.

→ There are two types of cyclones:

» The tropical cyclones

» The temperate cyclones

$\bold{\boxed{Tropical\: Cyclone:}}$

• Tropical cyclones are warm - core vortex circulation of tropical origin with a small diameter (some hundreds of kilometers).

• Often of an approximately circular shape, minimum surface pressure (less than 900 mb) with sustained maximum winds of at least 33m/sec.

• They are developed on the warm sea surface (26°C to 27°C) and move towards the land.

• The winds are lifted up by the moving of cyclones.

• The uplifted air gives heavy rainfall.

$\bold{\boxed{Temperate\: Cyclone:}}$

• Temperate cyclones occur when the cold,dry,denser air masses converge with warm,wet, lighter air masses.

• The warmer air, being lighter, is lifted up by the denser cold air and it results in the rainfall.
