When a storm revolves violently around a centre, it is termed a cyclone. It moves at a high speed ranging from forty to one hundred or more kilometres per hour. A cyclone may occur any time and at any place. The violent types of cyclones usually hit the tropics. The cyclone of Bangladesh generally originates from the Bay-Of-Bengal and blows towards that land. It is often accompanied by thunders and heavy showers. Before a cyclone commences unbearable heat is felt for a few days. Then suddenly one day the sky becomes terribly dark with clouds and strong winds begin to blow with flashes of lightning and the rumbling of thunders. Thus a terrible situation is created that lasts for a few hours. It causes a great havoc. A lot of people and other animals die. Dwelling houses are blown away. The tidal bore and the heavy showers wash away the stores of food stuff and leave the marks of terrible damage. The cyclone is usually followed by scarcity of food and outbreak of various diseases such as cholera, dysentery, diarrhoea, fever etc. which spread all over the affected areas. However, the great loss caused by cyclones can be reduced to a substantial extent. Using modern technology of weather forecast, prior warning can be given to the people who are likely to be affected by the cyclone. The people and their domestic animals can be shifted to the cyclone shelters. Moreover, a quick relief, medical treatment and essential medicines should be made available to the affected people just after a terrible cyclone.
