Peculiarities of turbulence in a flow with vortices

In the atmospheric boundary layer there exist groups of roll vortices contributing considerably to the momentum transfer, motion properties, etc. There are data pointing to an important role of such vortices in the formation of such a dangerous extreme weather event (EWE) as a tornado. It is known that helical turbulence mode is the cause of the similarity of atmospheric and magnetohydrodynamic turbulence. To clarify the peculiarities of EWE origination, experimental studies of MHD turbulence were carried out under laboratory conditions.
