Peculiarities of the temperature and humidity regime of the Right Bank of the Saratov region against the background of global climate trends

The temperature and humidity regime of the Right Bank is considered according to the data of four weather stations in three natural climatic periods – stabilization, the first and second waves of global warming. There is an increase in the rate of warming from one natural climatic period to another. Against the background of a progressive rise in temperatures, there is an increase in the amount of precipitation in the cold half of the year and its decrease in the warm one.

Characterizing the temperature and humidity regime of the Left Bank of the Saratov region against the background of the second wave of global warming

The article considers the temperature and humidity regime of the Left Bank of the Saratov region in various natural climatic periods of the state of the earth’s climate system – the first wave of global warming, stabilization, the second wave of global warming. It is noted that against the background of rising temperatures from one climatic period to another in the Trans-Volga region, the amount of precipitation in the cold half of the year increases. The trend in precipitation during the warm period is ambiguous.

Study of transport infrastructure on the example of assessing the frequency of one of the popular tram routes in Saratov

The paper presents a study of the transport infrastructure of the city with the main focus on public transport, in particular the tram. A sociological study was conducted that revealed the preferences of citizens in choosing the type of public transport, and the frequency of the actual movement and its correspondence with the data of a popular mobile application were also assessed.

Сравнительный медикогеографический анализ распространенности базальноклеточного рака кожи в Саратове

In the article, in a comparative analysis, for the periods from 1991 to 1998, 2015 and 2022, the issues of the territorial prevalence of basal cell skin cancer in Saratov are considered. The residential areas of patients were studied and mapped taking into account risk factors. The result of the study was an oncoecological analysis of urban landscape sites and the creation of a scheme for the active search for early forms of skin cancer.

Demographic situation in Saratov region (2010–2021)

The analysis of the current demographic situation is relevant since both demographic and migration growth are negative in the region. This article analyzes the main indicators of the demographic development of the region in the context of the COVID-19 pandemic against the background of previous years.

The impact of the COVID-19 pandemic on alcohol consumption in Russia (territorial aspect)

The analysis of changes in alcohol consumption by the population of Russia for the period from January 2019 to December 2020 in the context of the development of the COVID-19 pandemic was made. The main psychological and social reasons for the increase in the amount and frequency of alcohol consumption during this period are considered, and a discrepancy between the annual dynamics of alcoholic beverages sales and the development of the epidemic is revealed.

Dust load on ground air and street roads in the central (historical) part of Saratov

The article presents the results of atmochemical and lithochemical analysis of dust particles in the surface air layer and dust estimates along road curbs in the main types of urban landscape areas in the central part of Saratov.

Estimation of frequency response of the global temperature to change in radiative forcing

The Earth’s climate system (ECS) is considered as a linear system whose input is a change in the solar constant ΔI( t) and the output is an anomaly of the globally averaged surface temperature ΔT( t). The system input can be affected by other factors, and at the output their own temperature fluctuations and a random noise manifest themselves. All these factors are assumed to be independent of ΔI( t). The spectral analysis of monthly mean values of ΔI( t) and ΔT( t) shows the existence of statistically significant coherence.

The effect of changes in cosmic ray flux on general atmospheric circulation

A comparison of average daily values time series of the axial component of the global wind angular moment and galactic cosmic ray (GCR) flux was made. Using the superposed epoch method it is shown that the Forbush decreases of the GCR flux are accompanied by an increase in the average angular velocity of atmospheric circulation and, accordingly, by an increase in the zonal transfer.

Mineral composition and pollutant content in the bed load of watercourses on the territory of the city of Volsk

The article deals with the studies of the bed load of watercourses on the territory of the city of Volsk (Saratov region). The research shows that quartz to be the most widespread rock-forming mineral. As the proportion of quartz decreases, the calcite content increases. Ecologicalgeochemical state of the bed load in spring worsens as compared to summer due to the arrival of pollutants with melting snow from the urban watershed. The bed load with a high content of pollutants should be considered as an object of accumulated environmental damage.
