Assessment of future Central African air temperatures under the CMIP5 and CMIP6 project scenarios

Based on the results of the historical experiment of the CMIP5 and CMIP6 projects, the effectiveness of the scenario estimates (RCP/SSP1 2.6, RCP/SSP2 4.5 and RCP/SSP5 8.5) of the future air temperature for Central Africa for the IPSL and BCC global climate models is evaluated and the simulation results of these projects are compared with each other and with the observations of meteorological stations in the region, both for the historical experimental period and with the observations of recent years for the implementation of future climate projections.

Medico-geographical analysis of the incidence of colorectal cancer

The article discusses the issues of territorial prevalence of colorectal cancer in Saratov. A statistical analysis of morbidity and an oncogeographical analysis of urban landscape sites were carried out. The study of the regional features of the spread of this pathology, taking into account risk factors, will help in the development of the direction for the active search for patients.

Geoportals as a tool for access to cloud storage of metageosystems data

The article is devoted to solving the scientific problem of spatial data storage management using geoportal systems on the basis of solving the scientific problem of analyzing the patterns of spatiotemporal organization of complex dynamic hierarchically organized metageosystems. The paper proves that the problem of integrating large arrays of spatial information in spatial data infrastructures (SDIs) can be solved by designing multi-model storages operating on the basis of database management systems of different classes.

Zoning of the Russian steppe belt territory according to the level of socio-economic development

The study is comprehensive and describes the socio-economic zoning of the Russian steppe beltterritory. The method of zoning of the Russian steppe beltterritory is developed on the basis of the studied experience by scientists. The obtained results revealed a high degree of differentiation of the steppe zone of Russia by the level of socio-economic development.

Study of spatial distribution of elements in the system “water – bottom sediments” of the Uzynbulak creek of the Semipalatinsk test site

The results of studying the features of the spatial distribution of macro- and microelements in the “water – bottom sediments” system in the channel of the Uzynbulak creek (“Degelen” site of the Semipalatinsk test site, Kazakhstan) are presented. The studies were carried out in the summer of 2015. As a result of the study of the chemical composition in surface waters and bottom sediments of the Uzynbulak creek, the content of Li, Be, Na, Mg, K, Ca, V, Ni, Mo, Fe, Sr, Al, Zn, Ba, La, Ce, U was revealed.

Application of time series models for forecasting the global temperature anomalies

Spectral analysis of the time series for average annual values of the globally averaged surface temperature anomaly shows the presence of harmonics of the lunar nodal cycle with a period of 18.6 years, which can be used to predict the values of the series. Three models of the series were considered: autoregression AR(p), combined model of autoregression – integrated moving average ARIMA(p,d,q) and artificial neural network. It is shown that the ARIMA(4,1,4) model gives the best results for predicting the global temperature anomaly for three years.

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.
