Winter wheat is one of the main food crops that ensures the national food security of Ukraine with general production and high-quality grain. The area of winter wheat sowing ranks first in Ukraine, and the production of high-quality grain is of particular relevance. In the technology of its cultivation, the selection of varieties is a decisive factor in increasing yield and improving the quality of grain. The purpose of this study was to determine the influence of weather conditions and variety characteristics during the year on plant height, lodging resistance, and yield of winter wheat. This paper presents data on the results of the research of 20 varieties of soft winter wheat in the conditions of the Research-to-Practice Centre of the Mykolaiv National Agrarian University from 2017 to 2022. During the study, generally accepted methods were used: system approach, system analysis, analysis and synthesis, field and statistical method. The study also analysed the influence of variety characteristics and weather conditions in the years under study on the yield of soft winter wheat. It was established that the optimal plant height of winter wheat varieties ranged within 94.9-100.7 cm, at which the highest grain yield is formed, from 7.09 t/ha in the Staleva variety to 7.73 t/ha in the Duma Odeska variety. An increase in the height of the winter wheat varieties under study by 4.0-6.4% led to a decrease in yield from 4.5 to 20.9%. It was established that the awned varieties of soft winter wheat formed a higher grain yield, compared to the thornless forms, which had a higher plant height and less lodging resistance. The conducted studies confirmed that, on average, the resistance to lodging was higher in the thornless forms of winter wheat plants, which is 0.4 points higher than in the awned ones. The higher average grain yield of soft winter wheat was formed by varieties of spiny forms, which is 5.8% more than that of awned varieties. The obtained results will contribute to the wide application of the varieties of soft winter wheat under study for this soil and climate zone, which will further contribute to the increase in yield and gross grain harvests

Earthquakes can generate thermal anomalies in the atmosphere at low altitudes. Pending well-focused detailed studies, such phenomenon may be referred to as a precursor for earthquake prediction. However, today the pre-earthquake thermal anomalies are not clear enough. In this paper, the thermal anomalies prior to the April 25, 2015 Mw 7.8 Gorkha (Nepal) earthquake are investigated from the Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST), air temperature and Outgoing Longwave Radiations (OLR) data. The 2D and 3D wavelet transformation techniques are used to interpret the real time enhancement of the daily MODIS and OLR data before the impending earthquake. Using the wavelet density spectrum, pre-earthquake anomalies in MODIS and OLR are found in connection to the impending earthquake. The spatial images of MODIS and OLR show the evolutionary pattern of the emanation of ions from the epicenter and the surrounding area. The most important feature revealed by the spatial analysis is the eastward migration of temperature clouds due to a strong electric field. The satellite based LST data showed deviation, which crosses the upper bound by 5 °C. All the observations in our case study strongly support the notion of pre-earthquake thermal anomalies. Based on the analysis of the results, it can be concluded that the overabundance of ions from the seismogenic zone is responsible for prompting large temperature perturbations in atmospheric layers.

The Sochi National Park (SNP) occupies a considerable territory within the Greater Sochi municipality. It is located in several altitudinal zones. Therefore, climatic conditions within its territory are rather diverse. The average climatic conditions of SNP are rather well studied, but the global and regional climate change together with long tendencies in natural climate variability, require regular updating of corresponding changes on the SNP territory. This is important, first of all, for tracking changes and establishing reasons in local biodiversity changes. In the paper, we consider recent variations of the key climatic characteristics (air surface temperature and precipitation amount) in three elevation zones of the SNP. Analyses of mean annual and mean seasonal values reveal that besides common features, climatic tendencies are influenced by local conditions. Positive trends were established in temperature time series and negative in precipitation ones.

This paper summarizes the results of research on long-term variability of anomalies of annual temperatures in the Tyva Republic. The climate in the region is sharp continental, characterized by large temperature variability, both in diurnal and annual course. Anticyclone dry and clear weather dominates over the territory of the region. Multi-year temperature trends calculated for each month served as a basis for analysis of annual cycle of temperature trends at each station for the period of 1961-2016. The average annual temperature amounted to -3.4 ± 1.1 °С (1961-1990). Precipitation distribution is varied, for warm period precipitation is higher 80-87 % (annual precipitation is 180-325 mm), and for cold period precipitation is very low, about 20-13 %. Global warming is accompanied by changes in regional climate and seasonal features. The average annual air temperatures during 1975-2005 represent the warmest years. This is also reflected in the trends of the average monthly, seasonal and annual air temperatures. When comparing the longterm average air temperature in the period of 1975-2016 with the 1961-1990 period, from November to March increased by 1.3 °С and from April to October – by 1°С. The first years of the 21st century were the warmest years in the history of meteorological measurements in republic. During the period of 2000-2016 was one of, in the cold season the temperature increased by 1.9 °С and in the warmer time of the year – by 1.3 °С. However, it was frosty during January. This trend indicates an increased risk of higher fluctuations of the air temperature in the republic.

Mass balance bn is the most important indicator of a glacier evolution. However, after the decay of the USSR direct measurements of bn performed in 1985–1989 in the Inner Tien Shan, including the Sary-Tor Glacier in Ak-Shiyrak Massif, had been desisted. As a result the available series of the data were limited 1989. Measurements in this area were renewed only in 2015. This paper is devoted to restoring the continuity of the mass-balance series over the period of the gap in measurements and extending this series down to 1929, i.e. to the beginning of regular meteorological observations on the reference HMS Tien Shan (3660 m a.m.s.l.). Accumulation was reconstructed using a linear relationship of bn with the air temperature and precipitation sum. Reconstruction of ablation was based on its cubic relationship with the temperature (modified Krenke– Khodakov formula) or on two-parameter linear approximation using the air temperature and wind velocity. Thereby, the decade of direct instrumental measurements (1984/85–1988/89 and 2014/15–2018/19) resulted in deriving and analyzing continuous 90-year-long series of annual values of bn and its constituents, analytical type of referent glacio-meteorological equations being assumed unchanged in time. Reconstruction for the Sary-Tor Glacier reveals a dominant trend towards the mass loss with rare and short-time episodes of retarding the negative tendencies. The comparison made with the long series of mass balance of other glaciers in Asia indicates a certain degree of synchronicity, which is slightly disturbed in recent years: the degradation of Sary Tor Glacier tends to progress more intensively. Conclusions about its evolution are particularly relevant in connection with the assumption about the impact of the Kyrgyz-Canadian gold mining company «Kumtor Gold Company» on local ecosystems against the background of its interest in expanding the mining zone to the bowels of the Earth under the tongue of this glaciological object.

The climate change during cold seasons of 1995–2017 in the Central Caucasus is estimated, and its influence on the avalanche regime is shown. Data on the avalanche releases in the Central Caucasus for the period 1968– 2017 together with observations of high-altitude meteorological stations were used for the analysis. The paper presents estimates of snowiness of the winters and their frequency of occurrence in the area under investigation. The winter snowiness was noted to decrease since the beginning of the 2000s. The last decade of the period was not snowy, especially its series of six winters having very small amounts of snow. It is shown that in the second half of the XX century the heaviest snowfalls took place mostly in Januaries, and they were followed by releases of avalanches with the volumes exceeding 1 million cubic metres. In the early 2000‑ies, intensive January snowfalls were observed later, i.e. during the winter-spring period. In the warmer months March and April, the destructive potential of avalanches was noticeably smaller. In the present time, the warming and decrease of winter snowiness resulted in significant diminution of the avalanche hazard in the region. At the same time, on the background of general warming the certain increase in inter-seasonal variability of air temperature was noted. These changes may be compared to the warming of 1910–1945 when during its warmest phase the Europe suffered with one of the harshest winters in 1941/42. The swing of the «temperature pendulum» indicates that a harsh winter with heavy snowfalls and avalanches with catastrophic consequences may occur on the background of winters with mild and moderate avalanche danger. This is one of probable scenarios in the development of avalanche activity in the Greater Caucasus in the context of the current climate change.

The paper presents the analysis of meteorological criteria and the study of their influence on productivity of winter and spring grain crops through 20 years (1999–2018) in the Central zone of the Republic of Kalmykia. Meteorological information was analyzed differentially, i. e. for the entire period, over five-year terms (cycles), in separate years and seasons. The yield analysis was carried out according to the test results of 2170 variety samples of winter soft wheat, 334 samples of winter triticale and 503 spring barley varieties. Over the years the temperature was constantly becoming warmer. The average annual air temperature through 20 years exceeded the climatic norm on 1.30 °C (+10.7 °C). A similar situation took place both over five-year terms and in separate seasons. In winter the air temperature exceeded the norm by 1.7 °C (–2.5 °C), in the spring by +1.7 (+10.50 °C), in summer by +1.4 (+24.50 °C), in the autumn by +0.6 °C (+10.0 °C). In the important (summer) period of grain yield formation the amount of precipitation decreased by 25.6% (85.6 mm) of the climatic norm (115 mm). It was established that the main moisture accumulation (179.1 mm (55.1%) of precipitation) occurred in the autumn (25.8% (83.8 mm)) and in the spring (29.3% (95.3 mm)). Contrasting weather conditions made it possible to establish the effect of anomalous climatic parameters on productivity of winter wheat, winter triticale and spring barley. The results of productivity analysis through 2014–2018 showed that in the changed vegetation conditions winter soft wheat (3.19 t/ha), winter triticale (3.45 t/ha) and spring barley (2.53 t/ha) tended to increase average productivity by 0.34, 1.49 and 0.56 t/ha, respectively, compared with 1996–2000.

Introduction. The air temperature in the intake manifold is used by an electronic engine control unit to adjust the injection time of the fuel injector top. The intake air temperature is variable and depends on the operating conditions of the vehicle. When air intake temperature decreases, the duration of the nozzle opening pulse increases and, conversely, as air intake temperature increases, the duration of thenozzle opening pulse decreases.Materials and methods. The paper demonstrates the analysis of the air temperature effect in the intake manifold of the engine on the duration of the injector opening pulse while the engine is idling and when the vehicle is moving with different speed conditions on the flat, mountainous and alpine sections of the road.Results. As a result, the research showes that the movement of the car at high speeds on the flat sections of the road leads to a significant decrease of air temperature in the intake manifold and an increase in the duration of the injector opening pulse. Moreover, when the vehicle moves on the mountainous sections of the road, the effect of air temperature in the intake manifold on the nozzle opening impulse duration is insignificant, since the speed of the vehicle movement is influenced by the complexity of the terrain and the parameters of the mountain and high-mountain roads.

Проведен анализ причин ежегодного понижения температуры воздуха в южной части о. Сахалин в период с середины мая по конец июня с привлечением данных измерений, проведенных ИМГиГ ДВО РАН, Гидрометеослужбы и спутниковых карт NASA. Установлено, что температура воздуха в г. Южно-Сахалинске коррелирует с температурой воздуха на юго-восточном побережье о. Сахалин по данным измерений, проведенных в районе п. Охотское. Многолетние наблюдения показали, что примерно с 20-х чисел мая по 10 июня имеется хорошо выраженный температурный пик, после которого наблюдается не только снижение температуры, но и уменьшение среднесуточной скорости роста температуры воздуха. В июле скорость роста температуры воздуха восстанавливается, одной из причин этого является подъем температуры воды Восточно-Сахалинского течения, обусловленный окончанием таяния остатков ледового покрова на восточном шельфе о. Сахалин., The paper analyzes the reasons for the annual decrease in air temperature in the southern part of the Sakhalin Island in the period from mid-May to late June with the involvement of measurement data carried out by the IMGG FEB RAS, Russian Hydrometeorological Service and NASA satellite maps. It was found that the air temperature in Yuzhno-Sakhalinsk correlates with the air temperature on the southeastern coast of about. Sakhalin according to measurements carried out in the area of the Okhotskoye settlement. Long-term observations have shown that approx-imately from 20 May to 10 June there is a well-defi ned temperature peak, after which not only a decrease in temperature is observed, but also a decrease in the average daily rate of increase in air temperature. In July, the rate of increase in air temperature is restored. One of the reasons for this is the rise in water temperature of the East Sakhalin current, due to the end of the melting of the remnants of the ice cover on the eastern shelf of the Sakhalin Island., Экологические системы и приборы, Выпуск 11 2020

в последние три десятилетия в связи с современными изменениями климата и антропогенными нарушениями на территории Якутии происходит активизация криогенных процессов, которые негативно отражаются в ландшафтах и социально-экономической сфере в области вечной мерзлоты. Оценка современного состояния и тенденций развития мерзлотных ландшафтов Якутии в условиях глобального изменения климата и их влияние на устойчивость инженерных сооружений являются важной задачей для развивающихся районов Арктики и Субарктики России. Сильнольдистые криогенные ландшафты, занимающие около 30 % территории Якутии, в условиях современного потепления климата находятся в критическом состоянии. Результаты полевых наблюдений показывают, что любое антропогенное воздействие может привести к деградации вечной мерзлоты и ухудшению социально-экономической ценности этих ландшафтов. С этими ландшафтами в Якутии связаны наиболее населенные территории – аласные районы. Поэтому проблема изучения тенденций развития криогенных ландшафтов имеет не только экологическую, но и социально-экономическую, культурную и историческую актуальность., Current climatic changes and anthropogenic disturbances have intensified the development of permafrost-related processes in Yakutia during the last two decades, adversely affecting the landscapes and socio-economic conditions in this permafrost region. The main purpose of this paper is to assess the current state and trends in permafrost landscapes in Yakutia under global climate change. It provides a review of the current scientific literature, as well as analysis of field observations at monitoring sites of the Melnikov Permafrost Institute. The ice-rich permafrost landscapes which occupy about 25 % of Yakutia are in a critical condition under the current climate warming. The results of field observations show that any anthropogenic impact can lead to permafrost degradation and deterioration of the socio-economic value of these landscapes. Alases, which are related to these landscapes, are the most populated areas in Yakutia. Understanding the trends in permafrost-landscape dynamics has therefore not only ecological, but also socio-economic, cultural and historical importance.

The paper presents results of studies of the dynamics of snow cover characteristics along the Lake Baikal coast for the years 1961–2009. Statistical characteristics of the following elements: snow depth, duration of the period with snow cover, dates of onset and destruction of snow cover, were calculated from data of local meteorological stations. Mean annual snow depth in the region varies from 1 to 36 cm, while the maximal ten-day values changes from 12 cm on the West coast up to 60–86 cm on the East coast. Mean duration of the snow cover in the Baikal region is 138 days, while on the East coast it lasts for 178 days, and on the West one – for 126 days. Long-term trends of the snow cover characteristics are mostly statistically insignificant. However, at the end of the above period dates of the snow cover onset and destruction has been shifted to earlier dates. The inter-annual variability of these dates reaches 30 days. A linear dependence of the snow cover depth on the mean air temperature and the precipitation amount for the cold season was revealed with correlation coefficients from 0.31 to 0.89.

The estimation of glaciers of the Suntar-Khayata Mountains (the Northeastern Siberia) in the context of previously published data is presented. Under the background of current warming the glaciers in this region retreat enough quickly, they decrease not only in a real size, but also by the ice thickness. In this paper the mean summer temperature and solid precipitation of the key factors for glaciation, which indicate unfavorable conditions for the glacier existence at present time are presented as spatial distribution of trends (for 45 years, until 2012). The glaciers of the northern massif of the Suntar-Khayata have a negative ice mass balance as their entire surface is below the equilibrium line altitude. Mean thickness of superimposed ice on the glaciers of this massif was about 17 cm. Based on the assumption of climate variation in the Northern Pacific data it is suggested about the beginning of more favorable climatic conditions for the Suntar-Khayata glaciers.
