Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of tornado simulation devices, and particularly relates to a tornado control simulation device with multiple moving paths. BACKGROUND

[0002] A tornado is a funnel-shaped vortex occurring in a strong convective cloud, which has strong destructive power and obvious characteristics. It is a storm with a central vortex, great speed and spiral upward movement, and is accompanied by hail, lightning and heavy rain and other extreme weather, which can cause great damage to infrastructure and buildings and result in casualties. However, the existing weather radar is weak in determining and continuously tracking the tornado, and the direct observation of the tornado also has certain risks, which leads to the inability to accurately predict the tornado.

[0003] The damage form of the tornado to the building structure is a field to be explored, and the damage simulation of the tornado to the bridge is even less; meanwhile, the existing tornado simulation device does not mention the influence of the moving path of the tornado on the damage to the bridge.
