the 1970 Cyclone (Nov 12-13) with cyclonic surge of 3.05m to 10.6m high with wind speed of 222 km/h occurred during high tide causing most appalling natural disaster claiming 0.3 million human lives. On the 29 April 1991 a devastating cyclone hit Chittagong‚ Cox’s Bazar‚ Barisal‚ Noakhali‚ Patuakhali‚ Barguna and Khulna along with tidal bore of 5-8m high with wind speed of 240 km/h which killed 150‚000 human beings‚ 70‚000 cattlehead‚ and the total loss was about Tk 60 billion.

Introduction: Bangladesh is prone to a variety of natural hazards. It has witnessed the havoc of some of the worst natural disasters of the world due to tropical cyclones and storm surges. Floods and local seasonal storms are annual events which cause loss of lives and damage to housing‚ agriculture and economy. The country is also exposed to the risk of earthquakes. There are other natural hazard concerns such as coastal erosion and sea level rise due to global warming‚ which have been in the limelight

Differences between Cyclone and Tornado Cyclone and Tornado are two furies of nature that show differences between them in terms of their nature and phenomenon. (i) One of the main differences between cyclone and tornado is that cyclone develops over sheets of water. On the other hand tornado develops over land. (ii) Both of them differ in terms of their duration. Cyclone lasts for longer duration when compared to tornado. It is quite true that a tornado can last for only a few minutes‚ but

A tropical cyclone is a particular type of lowpressure system. It is called a hurricane in theUnited States and a typhoon in Asia. Tropicalcyclones are areas of warm‚ moist air risingrapidly. The upward ¯ow of air is de¯ected by theCoriolis effect (winds de¯ected by the Earth’srotation)‚ creating a rotation around a centralcore‚ known as the `eye’. Tropical cyclones areoften accompanied by very strong winds (gusts ofover 300 kilometres per hour have been recorded)‚torrential rain (1800 millimetres

A tropical cyclone is a rapidly-rotating storm system characterized by a low-pressure center‚ strong winds‚ and a spiral arrangement of thunderstorms that produce heavy rain. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy from the evaporation of water from the ocean surface‚ which ultimately recondenses into clouds and rain when moist air rises and cools to saturation. This energy source differs from that of mid-latitude cyclonic storms‚ such

An essay on cyclone A cyclone is a very violent storm. It never comes alone. Heavy showers of rain‚ thunder and lightning are its companions. When a cyclone blows‚ it moves round and round in the form of small circles. It always changes its course when it blows. It does not move in the same direction like an ordinary storm. It occurs mostly in the warm parts of the world. India is in this region of the world. Hence cyclones often blow over her. In cold countries there is no cyclone. The signs of
