The perimeter may measure 1,000 km but the powerhouse is located within the 100 kms radius. Nearer the eye, winds may hit 320 km ph. Tropical cyclones are intensifying swirls of cloud and rain which then progress into tropical storms. They spin clockwise in the northern Hemisphere and anti-clock wise in the southern hemisphere.
Between five and 20 kms tall when fully formed, they become self- sustaining and bloat until they hit cool land or ocean being of oceanic origin, they generally hit the east coast of the continents. The Indian subcontinent is the worst cyclone affected part of the world as a result of a low-depth ocean bed topography and coastal configuration. Stretches along the Bay of Bengal Coast-line have the world’s shallowest waters.
The relatively dense population and poor economic condition completes the picture. The population density in some of the coastal districts is as high as 670 person per square km compared to the state average of 26 persons per sq km. Cyclone strike here in May-June and October- November, with the monsoon’s onset and retreat. Cyclones of a diameter of 600 kms or more is one of the most destructive and dangerous atmospheric storms on the earth.
With about 6 per cent of the world wide cyclones, the Indian sub-continent is the worst cyclone affected areas. No universally acknowledged theory of occurrence of tropical cyclone is known today.
