A cyclone is a huge revolving storm. It is created due to very high speed winds blowing around a centre of a low pressure area. In general, cyclones are formed over the ocean. Once the cyclone is formed, it starts moving towards the land with a speed of approximately 120 km / hr . For the cyclone to exist, a constant supply of warm and moist air is needed. Two of the important factors that contribute to the development of cyclone are wind speed and temperature.
