• STRONG WINDS

• CYCLONIC STORMS

DIFFERENT NAMES OF CYCLONES

• COMMON NAME : TROPICAL CYCLONE

• INDIAN OCEAN :CYCLONES

• ATLANTIC OCEAN :HURRICANES

• WESTERN PACIFIC

(JAPAN &CHINA SEA) :TYPHOONS

WESTERN AUSTRALIA: WILLY WILLIES

CONDITIONS FAVOURABLE FOR THE FORMATION

• LARGE SEA SURFACE WITH TEMPERATURE ABOVE 270 C

• PRESENCE OF CORIOLIS FORCE• SMALL VARIATION IN THE VERTICAL WIND SPEED• A PRE-EXISTING WEAK LOW PRESSURE AREA• DIVERGENCE OF AIR IN THE UPPER LAYER

TORNADOES• FROM SEVERE THUNDERSTORMS SOMETIMES SPIRALLING WIND

DESCENDSLIKE A TRUNK OF ELEPHANT WITH GREAT FORCE.• CAUSES MASSIVE DESTRUCTION ON ITS WAY.• COMMON IN MIDDLE LATITUDES• THE TORNADO OVER THE SEA• IS CALLED WATER SPROUTS
