Method of influence on nonstationary thermal vortices

Method of influence on air vortices of small sizes is described in report. This method consists in the distribution of horizontal or vertical nets in the path of the vortex structure. Usage of the flat laser beam with visualization of flow by particles of magnesia allowed to study interaction of vortices with nets. Some probable physical effects of influence nets on propagation of nonstationary vortices are described.
