NATURAL HAZARDS AND DISASTERS

and moist air that can release enormous latent heat. (ii) Strong Coriolis force that can prevent tropical cyclone between ° - ° latitude). troposphere that creates local disturbances around which a cyclone develops. (iv) Finally, absence of strong vertical wind wedge, which disturbs the vertical transport of latent heat. Tropical cyclones are characterised by large pressure gradients. The centre of the cyclone is mostly a warm and low-pressure, cloudless core known as eye of the storm . Generally, the isobars are closely placed to wind belt is about - km from the centre. Spatio-temporal Distribution of Tropical Owing to its Peninsular shape surrounded by the Bay of Bengal in the east and the cyclones in India also originate in these two cyclones originate between °- ° north latitudes during the monsoon season, yet originate between °- ° N latitudes and to the west of ° E. By July the place of origin of these storms shifts to around ° N Sunderban Delta.
