论文摘要
大气温度不均匀性是折射变化指数的主要原因，导致激光束强度的强烈波动通过大气传播。结果表明，热（浮力驱动）对流的Kolmogorov-Bolgiano-Obukhov现象学可以在分布式混乱方法的框架中有效地描述此过程。为了支持理论考虑，已使用了城市气氛中直接数值模拟和测量值（基于波长为532nm和690nm的激光束）的结果。
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.
