Fluctuations of laser radiation intensity and flux in snowfalls are studied. It is found that as the optical depth increases, fluctuations of both flux and intensity first increase, then saturate, and then decrease. A similar behavior is observed for flux fluctuations when increasing the path length under close meteorological conditions. The data qualitatively confirm an irregular change of the spatial scale of correlation of the intensity fluctuations with increasing optical depth in a snowfall.
