CYCLONE MOCHA 2023: A GEOPHYSICAL DISASTER THROUGH REVOLVING HURRICANE

*Dr. Dhaval Patel and Dr. Dhrubo Jyoti Sen

ABSTRACT

Cyclone is a large revolving tropical storm caused by winds blowing around a central area of low atmospheric pressure. It is a tropical storm when the maximum sustained wind speed is more than 63 km/h. In India cyclones usually occur in the month of May-June and October-November. More cyclones tend to occur on the eastern side i.e., towards Bay of Bengal. The tropical cyclones are the phenomena of the weather where the circulating winds form over the sea due to the energy released by the evaporation and saturation of water over the sea. Cyclones are also known as hurricanes and tornadoes in the US while they are known as typhoons in China and Japan. These cyclones are responsible due to Warm temperature at sea surfaces, Coriolis force impact area that forms a low-pressure zone, atmospheric instability, increased humidity in the lower to middle levels of the troposphere, low vertical wind shear, etc. In India, the capital cyclone city is Sundarbans which is located in the south 24 Parganas.
