Cyclones
 The atmospheric disturbances which involve a
closed circulation about a low pressure centre
 They are Anticlockwise in Northern Hemisphere
and Clockwise in Southern Hemisphere
 Air blows in horizontal and
vertical motion
 There is air movement towards the centre so
they causes extensive damage to property and
life
 Copies rains will receive during the cyclonic
activity
 cyclones are given different names in different
geographical areas
Different Cyclones
 Atlantic Ocean : Hurricanes
 Western Pacific Ocean & : Typhoons
South China
 Indian seas : Cyclonic storms
 Australia : Willy-willies
TROPICAL CYCLONES
OCCUR IN TROPICAL REGIONS
STRONG AND POWERFUL
OCCUR IN SEA ONLY
Anticyclones
 A system where the pressure is higher at the
centre is termed as anticyclones
 The air blows is outward from the central area
 They are Clockwise in Northern Hemisphere
and Anticlockwise in Southern Hemisphere
 The anticyclones are associated with fine
weather
 Heated air thrown off by the centrifugal force
and the local cooling are responsible for this
eg : Middle latitude anticyclone always
produce the lowest temperatures of the season
Cyclone and Anticyclone
Windward side
 Any region, if naturally positioned along the wind
direction from which the wind blows
eg : the west of western Ghats is located windward
during the southwest monsoon
Leeward side
 The region which is positioned opposite to the
direction of the wind
eg : Tamil Nadu is in leeward side as monsoon wind is
obstructed by the Western Ghats
Windward side of
the Mountain
Leeward side of the
Mountain
Rain
Shadow
