“…Recent climatic changes dictate the need for a closer and more detailed study of climate-forming factors and their relationship within the climate system as a whole [1][2][3][4][5][6][7][8][9][10] . Cirrus clouds are one of the main sources of uncertainty in modern climate models and long-term weather forecasting [11][12][13][14][15] .…”

The paper presents a solution to the problem of light scattering by small randomly oriented ice crystals of arbitrary shape. The solution was obtained within the discrete dipole approximation. The particle sizes ranged from 0.02 up to 4 μm. The wavelength of the incident radiation is 0.532 μm, the refractive index is 1.3116. The influence of the number of dipoles per lambda and number of orientations on the convergence of the solution is shown. It is shown that the computation time has an exponential law dependence on particle size.

The work presents an analysis of the air temperature distribution in the atmospheric boundary layer (ABL) over Siberia, estimated from the observations of 24 aerological stations for 1981−2020. It is shown that on average per year, as well as in winter, spring and autumn, the ABL temperature decreases in the northeast direction in Siberia. In summer, there is a zonal temperature distribution: a decrease from south to north. In winter, there are temperature inversions in the ABL throughout Siberia. In spring, temperature inversions are observed in the polar areas of Siberia, subpolar latitudes of Western Siberia and central regions of Eastern Siberia, in autumn there are ones in temperate and subpolar latitudes of Eastern Siberia.

“…Cirrus clouds consisting of ice crystals with various shapes, size and spatial orientations essentially impact on the Earth's radiation balance and climate [1][2][3][4][5][6][7][8][9][10][11][12][13] . The simplest assumption used in theoretical works concerning cirrus clouds was that the crystals were randomly oriented in the atmosphere 14 .…”

Corner-reflection effect is the main feature at lidar soundings of cirrus clouds. In this paper, this effect is numerically studied in the case of plate-like quasi-horizontally oriented ice crystals of cirrus clouds. It is shown that the lidar signal as function of lidar tilt relative to the vertical can be used for inferring microphysical properties of ice crystals. In particular, if depolarization ratio at small lidar tilts is a small quantity it means that the crystals are plate-like and the plates are quasi-horizontally oriented. Appearance of a sharp step of depolarization ratio at the tilts of about 30° means that the transversal shapes of the crystals are regular. Otherwise, the transversal shapes are irregular.
