SIGNIFICANCE
The Cyclones level down inequalities of wind movement and pressure over the globe. Furthermore, they play a crucial role in the complex heat exchange process that takes place between various latitudinal zones. The cyclonic wind movements happen to be anti-clockwise in the northern hemisphere while in the southern hemisphere they are clockwise. Moreover, the cyclones can be either tropical or temperate/ extra-tropical depending on their area of origin and principal tracks followed.
EFFECTS
Cyclones can bring high winds and heavy rain. In extreme condition, the speed of winds may go over 240km per hour. These strong winds may cause a devastating phenomenon known as the storm surge, along with destructive torrential rain.
FACTORS RESPONSIBLE
1. Ample amount of warm temperature at the surface of the sea.
2. Instability in the atmosphere.
3. How the Coriolis force is impacting the area so that low- pressure area can be created.
4. When the humidity is high in the lower to middle levels of the troposphere.
5. Disturbance in the pre-existing low -level area.
6. When the vertical wind shear is low.
