Just as we pull soft drinks from a glass with a straw , a tornado pulls everything up. The question is where the tornado gets so much power ? Gets from the clouds. There energy is stored in a certain process. In extreme heat, the water vapor-laden air in an area becomes lighter at low pressure and rises and cools. Water vapor in the air accumulates in the clouds. During this conversion a lot of heat is released. This heat energy acts as the kinetic energy required to move the air. If the wind rises rapidly in very hot weather, a vacuum is created at the bottom. Then cold air started coming from all around. As soon as that wind comes, it gets hot again and goes up. Thus upward wind is created. This wind continues to rise in the form of a vortex. Cyclones often occur in the summer , but in the case of emergencies, they can take the form of tornadoes.
