The article focuses on the characteristics of air temperature and dew point changes observed during repeated fog events in the Absheron Peninsula in 2000...2022. For this purpose, continuous observation data of Heydar Aliyev International Airport was used. Here is an analysis of all types of fog by month of occurrence. The limits of total fog, Meteorological Optical Range ≤ 500 m. and 501...1000 m. are considered in the analysis. Repeating such criteria, attention was paid to the recorded air temperature and dew point indicators for I...III, IV...VI and X...XII months of the year. The analyzes show that the fogs observed in the peninsula are mostly recorded at a temperature of 6...8 0C. The most commonly observed dew point temperature ranges of 0,0...0,3 0C and 1,0...1,2 0C at all ranges of MOR in fog repeats. The results of the research are of particular importance for the planning of the work of all transport areas and the forecast of fogs.

The materials of our own research on the distribution of silicon, iron and the value of permanganate oxidability in the Irtysh River basin in the summer of 2023 presented. It has been established that the content of these components and their ratios are not the same in the water of rivers and lakes. The values of permanganate oxidizability (PO) for the water of the Irtysh River in most cases did not exceed the average values for natural waters of arid zones (5…10 mgO/dm3), as well as the maximum permissible concentrations for fishery waters. The water of floodplain lakes and storage lakes is more enriched with easily oxidizing organic substances (8.62…31.51 mgO/dm3). The maximum concentrations of silicon did not always correspond to the minimum values of total mineralization. The distribution of dissolved total iron is uneven and varies between 0.072...1.740 mg/dm3, with a maximum concentration in oz. Kurkol and the Balkyldak storage lake. From the upper to the lower sections of the Ertis, there was a slight increase in the concentration of iron and silicon, as a result, of the influence of an anthropogenic factor. The assessment of the quality of the water bodies of the Pavlodar Irtysh region was carried out on the basis of a Unified water quality classification system. The relationship of the average strength between silicon, iron and the value of PO is revealed. The data on the distribution of these components can be used for a more complete assessment of the water quality of the Yertis basin.
介绍了我们自己对 2023 年夏季额尔齐斯河流域硅、铁和高锰酸盐氧化值分布情况的研究材料。研究表明，这些成分的含量及其比例在河流和湖泊中并不相同。在大多数情况下，额尔齐斯河水的高锰酸盐氧化性（PO）值不超过干旱地区天然水的平均值（5...10 毫克氧化亚氮/立方分米），也不超过渔业用水的最大允许浓度。洪泛平原湖泊和蓄水湖泊的水更富含易氧化的有机物质（8.62...31.51 毫克氧化亚氮/立方米）。硅的最大浓度并不总是与总矿化度的最小值相对应。溶解总铁的分布不均匀，介于 0.072...1.740 毫克/立方米之间，最大浓度出现在盎司、......和......。库尔科尔（Kurkol）和巴尔基尔达克（Balkyldak）蓄水湖中的浓度最高。从额尔齐斯河上游到下游，由于人为因素的影响，铁和硅的浓度略有上升。对巴甫洛达尔-额尔齐斯河地区水体质量的评估是根据统一水质分类系统进行的。研究揭示了硅、铁和 PO 值之间的平均强度关系。这些成分的分布数据可用于对叶尔季斯河流域的水质进行更全面的评估。

The article presents the results of assessment of agrobiological resources of landscapes of agricultural use of Turkestan region under conditions of changing climate, which were based on the developed concept of reference yields of H. Tooming. To develop an algorithm for assessing the agrobiological resources of the region, a climatic research base for 1941...2020 was created for 18 meteorological stations located in different natural zones, which made it possible to determine the peculiarities of the formation of different categories of agricultural yields due to climate change. The obtained results of the research on the state of agrobiological resources of landscapes of the region on potential productivity of agricultural lands, on photosynthetically active radiation (PAR) input using the concept of reference yields in spatial and temporal scales have shown that there is a stable trend to increase the potential productivity of agricultural lands on photosynthetically active radiation input, climatic potential-possible productivity and decrease the potential productivity of agricultural lands on - photosynthetically active radiation input, climatic potential-possible productivity and decrease the potential productivity of agricultural lands on - photosynthetically active radiation input.

The paper presents the results of studies devoted to the assessment of the long-term dynamics of the volume of transboundary inflow of biogenic compounds to the territory of Kazakhstan along the Ile River. Based on long-term data from the State Monitoring of RSE «Kazhydromet,» the peculiarities of the transformation of the flow of biogenic compounds (nitrogen and phosphorus) along the river course, considering the influence of natural and anthropogenic factors, are analyzed. Information about the importance of studying biogenic substances in the formation of surface water quality, as well as river runoff’s role in the biological productivity and sanitary regime of final water bodies, is provided. The role of the transboundary flow of the Ile River as the main factor in forming the biogenic substances regime on the territory of Kazakhstan is highlighted. A quantitative assessment of the volume of average annual inflow of these compounds for the period from 2003 to 2020 is given, along with the main factors determining the transformation of nutrient runoff along the river course.

In this article, an analysis of calculation methods for determining the radiation balance and photosynthetically active radiation of soil and vegetation cover of agricultural land is conducted. The lack of continuous actinometric observations of solar radiation and radiation balance at meteorological stations in the Eurasian region leads to the widespread use of empirical and semi-empirical models based on climatic and geographical indicators. Mathematical models based on climatic indicators, which vary in spatial and temporal aspects and are formed on the basis of the principle of natural analogies, provide reliable and accurate data. However, calculation methods that use geographical indicators do not have physical and mathematical meaning, resulting in significant errors in the data. The aim of the research is to analyze indirect methods to identify their physical and mathematical justification. The need for the development of quantitative methods for assessing the effective use of photosynthetically active radiation to improve forecasting and management of agricultural land is emphasized.

This study analyzes and evaluates the relationship of surface and groundwater of the Syrdarya River within Kazakhstan. The share of groundwater recharge of the river was calculated by two methods: by genetically partitioning the total runoff hydrograph and by calculating low f low. The difference of groundwater flow into the river between the selected hydrostations is also calculated. A comparison of the obtained results for the quasi-natural and disturbed periods is made. In natural conditions, the infiltration of river runoff into underground horizons prevailed along the length of the Syrdarya River, however, under the influence of anthropogenic activity, the picture changed to the opposite: the discharge of groundwater prevails along the length of the Syrdarya River, including the emergence of filtration waters below the dam of the Shardara HPP, collector-drainage and discharge waters from irrigation f ields of the adjacent territory. Also, apparently, the truncation of spring flood peaks leads to an increase in the groundwater level and an increase in the share of underground river supply. Recommendations for the application of the methods used in the work are given.

The article presents the results of the study of polychlorinated biphenyls (PCBs) pollution of water and bottom sediments of Markakol Lake and rivers of its basin. Brief information about the importance of studying the accumulation and distribution of these dangerous xenobiotics in water bodies and watercourses of the republic in order to realize the tasks adopted by the Republic of Kazakhstan in accordance with the requirements of the global Stockholm Convention on Persistent Organic Pollutants (POPs) is presented. The conducted research f irst of all showed pollution of water resources and bottom sediments of the lake and rivers located in the protected area. Uneven distribution of toxicant concentration over the lake water area both in water and bottom sediments was revealed. The highest toxicant concentrations were registered in the water of the Kalzhyr River outflowing from the lake. In lake and river waters, 30 individual PCB congeners were detected, among which highly toxic dioxin-like and «marker» congeners are present. Other congeners with rather high toxicity were also found in water resources. Based on the scientific results of scientists from far and near abroad in the field of problems of distribution of these toxicants on the planet, the hypothesis about atmospheric transfer of these toxic compounds to this protected zone from highly PCB polluted territories was made.

Based on the scientific results of scientists from far and near abroad in the field of problems of distribution of these toxicants on the planet, the hypothesis about atmospheric transfer of these toxic compounds to this protected zone from highly PCB polluted territories was made.","PeriodicalId":256870,"journal":{"name":"Hydrometeorology and ecology","volume":"2 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141807281","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}

The article describes the development of toponymic systems in the territory of Saryarka. The materials and methods of toponymic research are considered. The formation of geographical names in Saryarka is connected with historical events. The article presents the achievements of researchers who studied the Saryarka region, where old toponymic and modern names are considered in detail. The article describes in detail the origin of toponyms in the context of outstanding historical events, such as the reign of Genghis Khan, the Era of the Golden Horde, the period of tsarist Russia. The toponymic systems of Saryarka are analyzed, which requires in-depth study in the future. Toponyms based on the names of plants and animals, names of people, tribes and genera are common on the territory of Saryarka. In the course of the research, a map of the genonyms and ethnonyms of Saryarka was compiled on the basis of actual data.
