“…Oscillations and vortices in the atmosphere are associated with a local excess of kinetic energy and free potential energy in the atmospheric layer. In atmospheric cloudiness, strong electric fields and associated plasma vortices are observed, which affect the genesis of atmospheric vortex structures [29][30][31]. Winter thunderstorms are recorded in middle and high latitudes.…”

The Earth’s atmosphere is affected by various ionizing sources. The maximum ionization of atmospheric particles by cosmic rays corresponds to the altitude of formation of tropospheric clouds. In the high-latitude troposphere for the region of the geomagnetic polar cap, in the winter period, the excitation of local cyclonic structures are observed which are accompanied with ice storms, with invasions into middle and subtropical latitudes. The time of excitation of such cyclones is about a day that is comparable with the time of excitation of tornadoes, which are generated at low latitudes. Localization of polar cyclones is not accidental. The region of the polar cap is connected with geomagnetic field lines extended into the tail of the Earth’s magnetosphere. This area is open for the penetration of cosmic rays. The ionization of aerosols in the stratosphere and the upper troposphere by precipitating particles of cosmic rays enhances the vortex activity of the atmosphere. The important role of the aerosol impurity is manifested in the generation of plasma vortices and in the accumulation of energy and mass in the atmosphere by vortices during condensation of moisture. Due to the cascade character of the ionization process, the influence of cosmic radiation turns out to be non-linear and increases with increasing pollution of the atmosphere. Aperiodic electrostatic perturbations, which play a remarkable role in the genesis of vortices, are stochastically excited in plasma inhomogeneities. During the interaction of plasma vortices and Rossby vortices, a large-scale vortex structure is formed and grows.

“…is depending on the gradient of vertical humidity z ξ ∂ ∂ , which could be found from the solution of the diffusion equation for water vapor (6). Some more detailed calculations of processes in the tornadolike vortex funnel performed within the framework of the model proposed here can be found in our works [7][8][9][10][11].…”

“…At present, it is obvious that the problem of the tornadolike vortex is important not only for our planet to determine the conditions for the formation of a tornado-like vortex, it is required to consider a number of hydrodynamic and plasma processes [1][2][3][4][5][6]. Along to prediction of a tornado-like vortex generation conditions [1][2][3][4][5][6][7][8][9][10][11][12] it is necessary to evaluate the characteristics of its quasi-stationary motion in a formed funnel: the mass of the moving moist air involved in the funnel and the size and form of the funnel. For a complete description of the phenomena, it is necessary to involve numerical calculations.…”

“…For a complete description of the phenomena, it is necessary to involve numerical calculations. We note that even for numerical calculations using powerful computers, the problem is very difficult because of the need to calculate multiphase turbulent flows with free, self-organizing boundaries [1,6]. However, "strict" numerical calculations, it is impossible to do without the use of many, often mutually exclusive, models.…”

The shape of the funnel of a tornado-like vortex formed in a humid atmosphere above the water surface (lakes, seas, oceans) is discussed. An equation that describes the funnel shape of the tornado-like vortices is derived. We have modified the obtained funnel profiles and their dependence on the flow rate using the modified data of humidity changes with altitude in the free atmosphere. It was showed that the shape of the funnel depends on the turbulent air viscosity, the turbulent moisture diffusion coefficient, and the flow rate is obtained. A vortex extended upward from the surface at least as far as cloud base (with that cloud base associated with deep moist convection), that is intense enough at the surface to do damage at one or more points along its path, should be considered a tornado.
