Cyclones🔥

* Cyclones are rapid inward air circulation around a low-pressure area. The air circulates in an anticlockwise direction in the Northern hemisphere and clockwise in the Southern hemisphere.

* Cyclones are usually accompanied by violent storms and bad weather.

* Cyclones represent circular fluid motion rotating in the same direction as the Earth. 

* The word Cyclone is derived from the Greek word Cyclos meaning the coils of a snake. It was coined by Henry Peddington because the tropical storms in the Bay of Bengal and the Arabian Sea appear like coiled serpents of the sea.

# Classification👇

* There are two types of cyclones:

Tropical cyclones; and

Extra Tropical cyclones (also called Temperate cyclones or middle latitude cyclones or Frontal cyclones or Wave Cyclones).

* The World Meteorological Organisation uses the term 'Tropical Cyclone’ to cover weather systems in which winds exceed ‘Gale Force’ (minimum of 63 km per hour).

# Tropical Cyclones👇

Tropical cyclones are violent storms that originate over oceans in tropical areas and move over to the coastal areas bringing about large scale destruction caused by violent winds, very heavy rainfall and storm surges.

Tropical Cyclones are one of the most devastating natural calamities in the world.

Tropical cyclones originate and intensify over warm tropical oceans.

# The conditions favourable for the formation and intensification of tropical storms are:

* Large sea surface with temperature higher than 27° C.

* Presence of the Coriolis force.

* Small variations in the vertical wind speed.

* A pre-existing weak low- pressure area or low-level-cyclonic circulation.

* Upper divergence above the sea level system.


# Extratropical cyclones are referred to as mid-latitude depressions, temperate cyclones, frontal depressions and wave cyclones.

These are active above the mid-latitudinal region between 35° and 65° latitude in both the hemispheres. The direction of movement is from west to east and more pronounced in the winter seasons. It is in these latitude zones the polar and tropical air masses meet and form fronts.
