The tornado is a 涡旋 ：dragon air around the shaft to rotate rapidly,by a tornado center pressure was reduced to attract,dozens of a thin layer of air currents from all sides,by inhalation 涡旋 bottom.and then into the vortex of 轴心,the strong wind always cyclones,the centre of pressure around 10% lower than the pressure.
The atmosphere of instability have a strong rising air currents,the current in the flow of traffic,it was further strengthened
In a vertical,horizontal with the speed and direction are never get wind of interaction,rising air currents in the troposphere central began to revolve,forming scale necessitated
With the scale necessitated to the development and progress,itself became fine and strengthened.meanwhile,a small area of increased support to that of the dragon born in the form,cyclones necessitated the same process and the formation of a tornado core
A tornado's whirling core and cyclones in,it was strong enough to make a tornado to the ground.when development reached the surface pressure,the ground with a sharp rise to form strom
