In India, the tropical cyclones are active in the Bay of Bengal and Arabian Sea during the period of April to December. From Arabian Sea, two times in a year, and through Bay of Bengal, 6 or 7 times in a year, these storms enter in our country. Some cyclonic storms originate in the sea and end on the sea coasts, while some others affect the common life badly. The intensity of these cyclonic storms depends at large on the temperature found in western parts and the low atmospheric pressure center that develops.
