Causes of non-Kolmogorov turbulence in the atmosphere

Abstract

In the present work, we briefly describe a model for atmospheric turbulence energy on the basis of experimental data obtained in Siberia. A series of new studies is considered and the results of our long-term experimental observations are summarized. The results of these studies form the basis for an explanation of some effects in interactions between optical waves and atmospheric turbulence. Our numerous experimental results point to the possible generation of so-called coherent turbulence in the atmosphere. When analyzing the problem, we proceeded based on our own experimental data and comprehension that the coherent turbulence is a result of the action of self-organizing nonlinear processes, which run in continuous media, including atmospheric air. The experimental data confirmed the effect of attenuation of light fluctuations in coherent turbulence.

Spatio-temporal trends and climatology of atmospheric chlorinated hydrocarbons over Pakistan

“…The lower temperature ranges during these months, reducing the vertical mixing and lowering the mixing height, result significant positive correlation of temperature with chlorinated hydrocarbons. The absence of this relationship over the Pakistan agrees with previous results from Polar Regions in the Arctic and in Antarctica (Lopez et al 2017;Esau et al 2012;Lukin et al 2016) for PCBs. Pollutants deposited on the Himalayas have attracted considerable attention recently, due to its impact on snow albedo, glacier melting, regional climate, and water resources (Frechette and Biondo 2020).…”

“…Surface temperature showed significant positive correlation with CH during winter (r=0.1-0.9), spring (r=0.4-0.5), autumn Recently, higher gas phase concentrations of chlorinated hydrocarbons for the warmer periods have been described in the atmosphere at Livingston Island, consistent with the measured volatilization of PCBs from soils and snow (Malagon et al 2012). Similarly, hexaclorocyclohexanes (HCHs) also show higher concentrations at higher temperatures in the Antarctic atmosphere (Chrysikou et al 2008;Lukin et al 2016). Other studies carried out in the Arctic have also shown that volatilization from seasonal snowpack is enhanced during high-wind speed events, affecting the concentrations in the gas phase (Kroll et al 2017).…”

“…High temperature causes the volatilization of pollutants in the atmosphere. However, once volatilized, lighter chlorinated compounds have higher capacity for long-range atmospheric transport (Lukin et al 2016) and then there is less chance to correlate with the wind.…”

Non-Classic Atmospheric Optical Turbulence: Review

“…A number of theoretical models have been proposed for accounting for turbulence containing coherence structures, which may be present in the close proximity of hard boundaries (see References [76,77] and references wherein). Such coherent structures appear because of the temperature or pressure gradients, and are formed as spatial vortices.…”

Wander of a Gaussian-Beam Wave Propagating through Kolmogorov and Non-Kolmogorov Turbulence along Laser-Satellite Communication Uplink

“…IGW are anisotropic structures. Lukin et al [17][18][19] suggested a hypothesis that atmospheric coherent structures were principal causes of considerable deviations of the Kolmogorov and Obukhov constants from their standard values. Turbulence observed in a coherent structure is called coherent turbulence, which is different from noncoherent Kolmogorov turbulence.…”
