Detailed explanation-1: -Cyclones/Hurricanes Cyclones may be referred to as ‘typhoons’ or ‘hurricanes’. A cyclone is an atmospheric system characterized by the rapid inward circulation of an air mass around a low-pressure center, accompanied by destructive weather.

Detailed explanation-2: -A tornado is defined as a violently rotating column of air extending from a thunderstorm to the surface of the Earth. The prerequisites for tornado formation are thunderstorm, moisture to feed thunderstorms, and temperature instabilities that are usually associated with spring and summer warming.

Detailed explanation-3: -A tropical cyclone brings very violent winds, torrential rain, high waves and, in some cases, very destructive storm surges and coastal flooding.

Detailed explanation-4: -Tsunamis are seismic sea waves and typically occur as a result of underwater earthquakes or volcanic eruptions, but they can also be caused by other external factors; such as ice calving from glaciers or meteorites. Tsunamis are tall waves which can extend as high as tens of metres, and are enerated by activity at sea.
