Popis: The characteristics of stationary, concentrated vortices of a special type are studied in a cylindrical coordinate system. A new solution for the problem of a concentrated vortex with three components of the velocity vector was constructed. It differs significantly from the previously known solution with two components of the velocity vector. The pressure distribution in a stationary concentrated vortex with and without Coriolis effect is found. The conditions under which the vortex is cyclonic are established. An analysis was conducted on ways to create a system of small vortices on the path of a tornado; with passage through these vortices, a tornado can weaken and disintegrate into a series of low-intensity vortices that are damped due to the forces of air viscosity and the friction force on the surface. Since the place and time of birth of a tornado are hard to predict and are often far from the necessary energy sources, a method for the organization of a rapid, protective obstacle system in the right place at the right time in the form of a system of concentrated vortices is discussed. It is proposed to use microwave electromagnetic radiation beams generated from airplanes or satellites as the source creating concentrated vortices on the tornado path.
