The results of experimental studies of the statistical parameters of fluctuations of focused laser beam radiation scattered in rain, drizzle, fog by precipitation particles along a 130 m atmospheric path are considered. The dependences of the probability density on precipitation form, scattering coefficient, and wind speed and its path-normal component are analyzed.
