Hint: A disaster is a major event that occurs over a short or long period of time and results in widespread human, material, economic, or environmental loss that exceeds the affected community's or society's ability to deal with its own resources. Natural and man-made catastrophes are routinely classified, while complex disasters, with no one root cause, are increasingly common in developing countries.
A cyclone is created by atmospheric disturbances in the vicinity of a low-pressure area, and it is frequently accompanied by powerful storms and severe weather.
The speed and direction of the wind, as well as temperature and humidity, all play a role in cyclone formation. The amount of water in the air is referred to as humidity. The temperature difference grows as the humidity in a location rises. The difference in temperatures between two places causes a cyclone to develop. When the air in a high-temperature location warms up and rises, a low pressure is formed. Cold air rushes in from the surrounding areas to fill the gap in the low-pressure zone.
Warm air rises and cools, condensing and forming clouds. The heat held by water vapour is released into the atmosphere as it condenses into droplets in the clouds. The process continues, and heat is released from the water vapour. As a result, falling water droplets and rising air combine to form a thunderstorm, which can grow into a cyclone depending on the weather.
Note: The antithesis of a cyclone is an anticyclone. In the Northern Hemisphere, the winds of an anticyclone cycle clockwise around a high-pressure centre. The air enters from the top and sinks to the bottom. Fair weather is common in high pressure areas.
