Abstract
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.

Summary
Characteristics of the turbulent flow of moist air in the etc. in the course of its existence the tornado-like vortex funnel of tornado-like vortices can change the shape of the funnel, often, before it disappears, the tornado-like vortex funnel thins, becomes snake-like and . We note that even for of the formation of a tornado-like vortex should show how, due numerical calculations using powerful computers, the problem is to the development of instability, a funnel will form. “strict” investigate the mechanisms determining the shape of the formed numerical calculations, it is impossible to do without the use tornado-like vortex funnel. How to choose an adequate model of turbulence (algebraic, k-ε model, It was assumed in [7] that a vortex flow of a two-phase (dry air etc.) or the use of additional, often not accepted, hypotheses about and a water vapors) media takes place in tornado-like vortex funnels. Along with numerical droplets resulting from surface condensation of air moisture on wall calculations of such flows, modeling problems that allow an exact surface.
