contents In this paper, we propose a new theory on tornadogenesis from the perspective of vortex tubes based on Kelvin-Helmholtz Theorems. When the pressure difference between the lowest pressure line from the wall cloud down to the ground and its surroundings is large enough, the increase of vorticity inside the squeezed vortex tube can reach the tornado level, and thus a tornado is born. When the pressure difference increases, the tornado strength increases. When the pressure difference decreases, the tornado strength decreases. The decay of tornadoes is caused by the decreasing pressure difference. This is our theory of the entire tornado lifespan.
