Abstract

The results of the measurements of astroclimate characteristics in Special Astrophysical Observatory of RAS (SAO, North Caucasus) in 2012 and 2016 are presented. Experimental researches of turbulence structure in the dome specialized room of the Big Telescope Alt-Azimuthal (BTA) at the closed and open dome are executed. Research of distribution of velocities of the airflows movements in points on the volume of dome space is made and the experimental picture of air-flows is restored. Presence in the dome room of BTA of large vortex coherent structure that improves the images quality of the telescope is established.
