Authors: Pryakhina S. I., Kotova A. A.

The article presents the results of work on the study of synoptic conditions for the formation of a dangerous weather phenomenon for the territory of Western Siberia – a thundersnow. The material for the study was the archive of aerosynoptic material from the Khanty-Mansiysk Air Meteorological Center.

Urbanized framework of the Volga-Ural macroregion: Assessment of the potential intensity of economic relations

Authors: Preobrazhenskiy Y. V.

Identifying the spatial structures of economic activity within a supra-regional entity is an urgent scientific task. In this study, it is solved using a combination of a framework approach and a model analog of the gravitational interaction for the cities of the Volga-Ural macroregion.

Possibilities of using space-cartographic methods in strategic environmental assessment

Authors: Zheleznov Y. A.

This article analyzes the current state of space-cartographic research methods and their application in strategic environmental assessment using the example of processing space-cartographic material and its digitalization in order to form a digital management platform that will further allow developing necessary measures for effective environmental management. The basics are briefly outlined and the possibility of using space-cartographic methods to study the state of geoecosystems for solving highly specialized problems in the context of strategic environmental assessment is considered.

Population dynamics of Volgograd, Samara and Saratov regions: Contribution of migration

Authors: Ustavshchikova S. V.

Volgograd, Samara and Saratov regions are neighboring regions. Demographic development in the regions has general trends. Migration is becoming the main component influencing the differences in population dynamics in the regions. The Samara region continues to attract both interregional Russian and international migrants.

The prevalence of non-Hodgkin’s lymphomas in Saratov (medico-geographical analysis)

Authors: Konopatskova O. M., Makarov V. Z., Kuzinova Y. K., Reshetarova D. A.

Malignant neoplasms of the lymphatic system, which are characterized by damage to groups of lymph nodes and/or damage to internal organs are called lymphomas. The analysis of statistical data shows that there is incomplete information about the incidence in specific regions. The study of the prevalence of lymphomas, the need to monitor the incidence, and the identification and analysis of possible links between pathology and urban environmental features are an urgent problem. The paper analyzes the dynamics of the incidence of non-Hodgkin’s lymphoma in Saratov from 2009 to 2019.

Some population mortality indicators of the large region of Volga federal district

Authors: Ustavshchikova S. V.

Reducing the mortality rate of the population: general, in childhood and people of working age is a priority goal of the federal and regional authorities. However, an increase in the proportion of the population in older ages in the total population, and an increase in life expectancy leads to an aging of the population as a whole, and, consequently, to an increase (all other things being equal) of the relative mortality rates of the entire population.

Assessment of the geoecological state of surface watercourses in the Slavsky district, Kaliningrad region (summer hydrological season)

Authors: Spirin Y. A., Zotov S. I.

The paper provides an assessment of the geoecological state of surface watercourses in the Slavsky district, Kaliningrad region in the summer hydrological season. For this purpose, the choice of watercourses for research was carried out, which, in aggregate, could characterize the river network of the Slavsky district as a whole, they were: r. Zlaya, r. Shluzovaya, r. Nemoninka and r. Osa. Water samples were taken for hydrochemical analysis and the hydrometric characteristics of the rivers were measured.

The urban settlement pattern on the banks of some rivers in Europe: Search for inter-city interval

Authors: Preobrazhenskiy Y. V.

The study continues to identify the typical interval between cities on major rivers in the search for patterns in the organization of geospatial elements, including point (cities) and linear (rivers) objects. It is stated that the latter are divided into approximately equal segments measured by the river (inter-city intervals). This article examines the features of urban population distribution along the banks of six major rivers in Europe. Typical inter-city intervals were identified for them.

On the manifestations of climate change in the wind regime in the territory of Syunik marz (Armenia)

Authors: Margaryan V. G., Avetisyan G. D., Khachatryan G. A., Margaryan P. N.

The manifestations of climate change in the regularities of the wind regime in the territory of Syunik marz of Armenia are considered. Monthly wind data for the period 1966–2018 of six weather stations were used as a source material. It was found that at all meteostations, except for Kapan, currently operating in the territory of Syunik marz there is a tendency towards a decrease in wind speed for 1966–2018. The number of cases of wind directions and calmness also fluctuates, due to climate changes, which are presented in the work on the example of the Goris weather station.

Facies structure of the chalk natural landmark of the nature monument “Chalk slopes with calcephil plants near town Volsk”

Authors: Makarov V. Z., Volkov Y. V., Arhipova E. A., Nevryuev A. M., Melnikova E. S.

The article presents the results of landscape-ecological studies of the site of the natural monument “Chalk slopes with calcephil plants near town Volsk” in the Saratov region. For the first time, the facies rows of the chalk buttes of the Volsky Pre-Volga region are identified, their characteristics are presented, and the conservational risks to calciphytic diversity are indicated.
