Measurements of the astroclimate over the territory of Special astrophysical observatory of RAS

摘要

The results of the measurements astroclimate characteristics in Special Astrophysical Observatory of RAS (SAO, North Caucasus) in 2012 and 2016 are presented. The results obtained from long-term series of observations of day and night astroclimate in SAO. Presence over the territory of the SAO of coherent turbulence in which the image quality of telescopes improves is established. The influence of the type of underlying surface and the direction of wind speed on the mode of appearance of coherent turbulence is found out. It was found that the reason for its appearance is the mountainous terrain and uneven heating of the underlying surface.
