One of the factors determining the spectral composition of turbulence is the stratification regime. The effect of surface air layer stratification on the deviations of a turbulence spectrum from the Kolmogorov–Obukhov model is studied based on the processing of time series of fluctuations in meteorological parameters recorded by acoustic weather stations. A significant correlation between the stability characteristic (Monin–Obukhov number) and the exponent of the power-law model of the spectrum of temperature fluctuations is found from the comparison of their dynamics. An empirical model of the dependence of the spectrum exponent on the stability characteristic is suggested. The model makes it possible to estimate changes in the parameters of the spectral structure of small-scale turbulence based on estimates of the magnitude and direction of turbulent heat and momentum fluxes. The dependence reflects the features of generation of temperature turbulence under different stratification of the surface air layer. Information on turbulent spectral parameters derived from stratification estimates can be further used to solve problems of optical and acoustic wave propagation and atmospheric sounding.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"38 2","pages":"130 - 137"},"PeriodicalIF":0.9,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1024856024701720.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work studies jet streams and atmospheric turbulence affecting the surface SO2 content over Listvyanka station. The cases are considered where the surface SO2 concentration tends to increase at negative vertical turbulent specific heat fluxes. This occurs against the background of jet streams within the lower air layer and large vertical wind speed shear below the altitude of the jet stream generation. A vertical turbulent specific heat flux in the surface air layer can serve a key indicator of possible positive relationship between the surface SO2 concentration and the total kinetic energy of turbulence. The analysis has shown that SO2 concentration tends to increase at negative vertical turbulent temperature fluxes against the development of low-level jet streams. In similar situations, but with positive or near-zero temperature fluxes, SO2 concentrations usually remain at a background level.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"38 2","pages":"180 - 187"},"PeriodicalIF":0.9,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work is devoted to the study of wave structures and turbulence in a stable ABL with the use of the data of our experiments conducted in 2023. In these experiments, two pulsed coherent Doppler lidars (PCDLs) horizontally spaced 3250 m apart were simultaneously involved. The analysis of the experimental results has shown that from the measurements of two PCDLs it is possible to determine the time shift of the moments at which the leading edge of an atmospheric wave passes through the lidar locations; using this shift, one can determine the propagation velocity of the atmospheric wave. For the first time in our lidar experiments, the case of atmospheric wave propagation in the layer at heights from 200 m to 1 km with a maximum amplitude of quasi-harmonic oscillations of the vertical component of the wind velocity vector of about 4 m/s (at a height of 400 m) has been revealed. It has been found that due to the transfer of energy from an atmospheric wave to small-scale wind fluctuations, it is possible to increase the turbulent energy dissipation rate by four orders of magnitude in just a few tens of minutes.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"38 2","pages":"166 - 179"},"PeriodicalIF":0.9,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, within the framework of the physical optics method, properties of light backscattering by horizontally oriented cirrus cloud ice particles of the “plate,” “column,” and “hollow column” types are numerically simulated. The simulations are carried out for particles ranging in size from 10 to 316 µm for wavelengths of 0.532 and 1.064 μm; the complex refractive index of ice is 1.3116 + i1.48 × 10−9 and 1.3004 + i1.9 × 10−6, respectively.
