The features of the thermal regime of the surface air layer in the Debed river basin are considered. A statistical analysis of the average annual and average seasonal values of air temperature from 1964 to 2018 was carried out, two periods were identified, their time course was shown. The analysis was carried out using data from six meteorological stations representing the lowland, mountain and high-mountain climatic zones of the Debed river basin. A correlation was obtained between the absolute altitude and the monthly average values of air temperature for January and July, which can be used to assess the thermal conditions of unexplored or poorly studied territories and for cartography. The time course of average values of air temperatures for the seasonal period has been studied. Analysis of trend lines of temporal changes in air temperatures shows that in all situations on the territory of the basin as a whole, there is a tendency of temperature growth. Moreover, with a range of interannual fluctuations, a break in the course of temperatures in the early to mid 1990 is clearly visible, after which their significant increase began. It turned out that a significant increase in seasonal temperatures is observed especially over the period 1993-2018, which means that the annual warming after the mid 1990 occurred primarily due to summer and spring seasons. The regular dynamics indicates that in the studied area in terms of temperatures, a tendency of softening winters, a decrease in the water content of rivers, aridization of the climate. The results obtained can be used to assess the regularities of the spatial-temporal distribution of the temperature of the study area, to clarify the thermal balance, for the rational use of heat resources, as well as in the development of strategic programs for longterm analysis.

Abstract The article presents results of research on the development of air temperature and relative humidity at a height of 5 cm above the active surface of the terminal lateral moraine of the Aavatsmark Glacier, relative to its exposure in the summer season of 2010. Variations in the two conditions were analysed for five measurement sites situated on northerly (SN), easterly (SE), southerly (SS) and westerly (SW) slopes, as well as on the flat top surface of the moraine (STop), in different weather conditions. The article also includes a temperature and humidity stratification in the near surface air layer (5-200 cm) above the moraine. The issues were investigated for mean values from the whole period of research, as well as for individual days demonstrating distinct degrees of cloudiness and wind speed.

The paper presents the results of studies of protective strips located in the Voronezh region in the Rossoshansky district. The characteristic of biometric data of forest belts of the same age and their dependence on the density of planting, width of strips and row spacing is given. The comparison of the soil, its impact on the growth and development of trees is displayed. The influence of the design of protective forest stands on the temperature of the surface air layer is also shown. The state of the plantings and the factors that adversely affect it are determined: the lack of care measures, deforestation, clutter and the presence of a large number of diseases and pests.

The article discusses topical issues and problems of the impact of industrial road transport on the environment, namely: emissions of pollutants into the atmosphere depending on the type of fuel and their negative impact on human health. The significant increase in the vehicle fleet is causing great harm in the form of harmful emissions from fuel combustion systems, which cannot be dealt with standard car cleaning systems. The situation is aggravated by the fact that car emissions are concentrated in the surface air layer - precisely in the zone of our breathing. Low- quality gasoline is still used, polluting the environment. About 280 harmful substances were found in the exhaust gases of cars, including carcinogenic benzopyrenes, nitrogen oxides, lead, mercury, aldehydes, carbon oxides, soot, hydrocarbons. These emissions increase significantly when starting off or increasing speed. Diesel engine emissions are different from gasoline engine emissions. A diesel engine burns fuel more completely, oxidizes less carbon and produces less non-combustible hydrocarbons. But, at the same time, due to the lack of air in the diesel engine, more nitrogen oxide is formed. Diesel engines also emit soot. Gas emissions from transport into the atmosphere are exposed to sunlight, which leads to photochemical reactions leading to the formation of NО2, 0з, peroxides, benzopyrene (C22H14) and other compounds. In addition, each vehicle emits rubber dust into the atmosphere when its tires are abraded and worn out. Accordingly, the scale of damage caused by transport to the environment and people is also increasing. The article analyzes the existing and promising types of fuel and the reduction of the technogenic impact of industrial road transport on the environment in Ukraine.
