What stops a tornadoAs the warm air powers up through the centre of the tornado and continues up through the thunder cell, the descending cold air moves towards the outside of the thunder cell and eventually wraps around the rotating system, cutting off the in flow of warm air witch feeds b the tornado.

This cold air completely wraps around and chokes off the tornados air supply, the tornado begins to weaken, becoming thin and rope like. This is the dissapating stage, and the tornado often dissolves within minutes. During the dissapating stage the tornado becomes highly influenced by the direction of the surface winds, and can be blown into fantastic flexible patterns.
