“…Yershin and Yershina reveal a potential activating mechanism of such threatening phenomenon like twister or tornado. The understanding of this process came as a result of the discovery and study of secondary (circulating) currents within absolute liquid (gas) currents, named Taylor-Gertler's free vortices [22]. Documentary evidence is employed to present the history of tornadoes in the Czech Lands (recently Czech Republic) in AD 1119-2010.…”

Thermal energy transfer in the atmosphere occurs from a high temperature zone to a low one by means of convective vortices where mechanical energy is produced. There are two ways of driving vertical flow in the core of a vortex: (1) by the direct action of buoyancy acting on hot air and (2) by producing a vertical pressure gradient along the axis of a vortex because of core development involving the lateral spread of the vortex with height. In particular, it indicates that the intensity of convective vortices depends on the depth of the convective layer via thermodynamic efficiency, the enthalpy perturbation across them, and the existence of sources of vorticity. The atmospheric vortex engine (AVE) is a device for producing an artificial vortex. The operation of AVE is based on the fact that the atmosphere is heated from the bottom and cooled at the top. By artificial vortex generation, it is aimed to eliminate the physical solar updraft tower and reduce the capital cost of solar chimney power plants. This paper reviews natural convective vortices and vortex creation via physical principles of vortex generation. Vortex analysis and modelling are presented. Furthermore, a new model of a solar vortex engine (SVE) is proposed and discussed. An idea on utilizing the solar energy as the heat source for establishing the vortex and operating the SVE model is adopted. The SVE model is feasible and promising for electrical power generation.

“…Este evento meteorológico ocurre en pocos cientos de metros y tiene un tiempo de vida de pocos minutos a horas pudiendo llegar a ocasionar catástrofes, perjuicios económicos e incluso pérdida de vidas humanas [5][6]. Se han registrado en todos los continentes a excepción de la Antártida, siendo Norteamérica la zona del planeta con el mayor número contabilizado [7].…”
