On this day, 39 years ago, on October 9, 1986 (September 6, 1986, the lunar calendar), scientists in the former Soviet Union uncovered the mystery of tornadoes. On October 9, 1986, scientists from the former Soviet Union uncovered the mystery of tornadoes. Scientists at the Institute of Theoretical and Experimental Physics in Moscow have successfully revealed the secrets of tornadoes, whose scale of damage is comparable to that of a nuclear explosion. The theory they proposed about the gravitation-thermal process within tornadoes not only reveals the nature of this special atmospheric phenomenon, but also becomes the key to solving the dynamic problem. Viktor Kushen, author of the new theory and PhD in technology, found that tornadoes are not "dust lords" as previously believed, but that their funnel-shaped vortices are spiraling rain. The rotation inside the vortex reaches supersonic speed. According to scientists 'calculations, when the diameter of the vortex is 200 meters, the power of the swirling flow in the tornado reaches 30,000 megawatts, which is equivalent to the power of ten huge power stations. Tornadoes are preceded by cyclones, which are created when cold and hot atmospheric fronts collide. If the cyclone encounters lightning clouds, rivers and lakes with a lot of rain on the way, the water will be taken away by the cyclone and turned into a rapid whirlpool. According to the laws of physics, the resulting tornado funnel-shaped vortex will rise into the cold upper atmosphere. Water freezes quickly here, releasing energy. The new perspectives of Soviet scientists prompted people to consider the possibility of gaining new impetus.
