Abstract
The results of synchronous optical and meteorological measurements of Fried's coherence length on Big solar vacuum telescope are presented. The decrease of this parameter in winter time was detected. Spectra of wind speed and temperature inhomogeneities at the time of Fried parameter measurements were investigated.
