What's the difference between a dust tornado and a tornado? Xu Jianguo, a meteorological expert and chief expert of Tongliao meteorological station, told polar news reporters that tornadoes are generally accompanied by strong convective weather, mostly in rainy days, while dust tornadoes mostly appear in sunny days. At the same time, tornadoes extend from the air to the ground, while dust tornadoes develop from the ground to the air. Tornadoes cause greater harm, while dust tornadoes cause less harm**
"Because the surface is not heated, the vortex is not formed." Xu Jianguo said that the maximum dust tornado can reach more than 20 meters. "From the video, it's sunny. It should be a dust tornado, but it's powerful." Xu Jianguo said.
