Strong chaotic fluctuations of laser beams propagating through temperature inhomogeneities in the atmosphere

The atmospheric temperature inhomogeneities are the main cause of the index of refraction variations resulting in strong fluctuations of intensity of the laser beams propagating through the atmosphere. It is shown that the Kolmogorov-Bolgiano-Obukhov phenomenology of the thermal (buoyancy driven) convection can effectively describe this process in the frames of the distributed chaos approach. Results of the direct numerical simulations and measurements in the urban atmosphere (based on the laser beams with the wavelengths of 532nm and 690nm) have been used in order to support the theoretical considerations.
