How are cyclones formed

Types of cyclones
There are 4 types of cyclones :-
Tropical cyclone Polar cyclone Mesocyclone Extratropical cyclone.

Tropical
Cyclones
• Tropical cyclones are what most people
are familiar with because these are
cyclones that occur over tropical ocean
region.
• Hurricanes and typhoons are actually
types of tropical cyclones, but they
different names so that it's clear where
that storm is occurring.
• Hurricanes are found in Atlantic and north
pacific; typhoons are found in Northwest
pacific.

Polar cyclones
Polar cyclones are cycles that occur in polar region like Greenland,
Siberia and Antarctica. Unlike tropical cyclones, Polar cyclones are
usually stronger
Mesocyclone
Mesocycle is a cycle that occurs what part of a thunderstorm cloud
starts to spin, which may eventually lead to a tornado. 'meso' means
'middle'

Effects of
cyclones
• Cyclones causes heavy rainfall and
landslides.
• They harm the ecosystem of the
surrounding region.
• Agricultural land is severely
affected, especial in terms of water supply
and soil erosion.
