The influence of circulation factors on the quantity of atmospheric precipitation in the cold season in Western Siberia

Introduction. The work is devoted to the analysis of the influence of different states of the circumpolar vortex on local features of the geopotential fields, which, in turn, determine the variability of cold season precipitation for the studied territory of Western Siberia. Data and Methods. A statistical analysis of time series of seasonally average values of the precipitation amount in the cold season was performed, obtained from 33 meteorological stations located within the selected coordinate area.

Research of spatial distribution of electromagnetic fields of industrial frequency in the central part of the city of Saratov

The cartographic research of electric and magnetic fields of industrial frequency in the central part of Saratov was performed. Measurements by means of the Gigahertz Solutions ME 3830 B M/E Analyser were executed in the 177 points within the built-up territories and recreational zones. The research showed that tension of electric fields and magnetic induction everywhere do not exceed hygienic standards, but in 15,8% ofmeasurement points excesses of approximate safe level ofmagnetic induction were revealed accordingtothe latestforeign researches.

Small streams and water reservoirs as indicators of environmental problems in agricultural landscapes (on the example of the Belgorod region)

The main object of the article is to show indicator functions of small water bodies (streams, ponds) for 4 rural areas in agricultural landscapes (Belgorod region). In the course of the study the groups of anthropogenic objects with their special impacts are identified and ranked. The correlation between concentrations of chemical forms of biogenic elements (N, P) demonstrates the contribution of typical problems of agricultural landscapes in ecological situation (rural areas) as well as contribution of adjacent urban areas.

Green technologies in the manufacturing industry in Russian regions

The green transformation of the country’s economy is a crucial process for the sustainable development of spatial socio-natural systems. This transformation is closely linked to the broader process of digitalizing the economy. However, the introduction of green technologies into Russian industries is uneven, as shown by the analysis of the representation of advanced green manufacturing technologies in different regions. This analysis has revealed a lack of using green technologies and a low number of regions that generate these technologies.

Statistical analysis of air temperature changes according to long-term observations of the V. A.Mikhelson Meteorological Observatory of RSAU – MTAA

Introduction. The purpose of the study is to assess the dynamics of changes in air temperature indicators and its impact on agronomic systems, based on long-term observations of the V. A. Mikhelson Meteorological Observatory of RSAU – MTAA. Materials and Methods.

Saratov children’s playgrounds: Analysis of the ecological and geochemical situation

In a modern large city, it is mandatory to have playgrounds in residential areas. The level of social well-being and well-being of urban space is also assessed by the presence of a children’s playground in each residential courtyard. However, from a city-ecological point of view, is it advisable to organize parking on boulevards, in small squares, in courtyards next to car parks?

Open remote sensing data for the identification of archaeological sites

Archaeology, as a science, is constantly evolving and embracing various interdisciplinary methods. Currently, geoinformation technologies and aerospace remote sensing, along with other remote sensing methods, are becoming some of the primary tools at various stages of archaeological research. This study explores the potential of using open-source remote sensing data to identify archaeological sites.

Формирование урболандшафта северных приморских территорий в суровых климатических условиях на примере континентального побережья Охотского моря и Гудзонова залива

Природопользование в северных широтах Земного шара в большинстве случаев зависит от минерально-сырьевой базы и иногда от степени населенности. Для рассматриваемых районов, хозяйственная деятельность ограничена природно-ресурсным потенциалом и суровыми климатическими условиями для проживания постоянного населения. В природно-хозяйственном отношении, прибрежно-морская зона исследуемых водных объектов практически малоосвоена, труднодоступна и удалена от экономически развитых и густонаселенных районов.

Влияние циркуляционных факторов на количество атмосферных осадков холодного сезона на территории Западной Сибири

Аннотация. Введение. Работа посвящена анализу влияния разных состояний циркумполярного вихря на локальные особенности полей геопотенциала, которые, в свою очередь, определяют изменчивость осадков холодного сезона для исследуемой территории Западной Сибири.

Нейронные сети в задачах обработки и классификации геоинформационных данных при локализации древних переправ и островов при формировании саратовской городской агломерации

Настоящая работа посвящена технологиям нейронносетевой обработке геоинформационных данных на примерах их применения к прикладным задачам. Представлены основные подходы, алгоритмы и методы обработки данных, включая методы геоинформационных систем, алгоритмы кластеризации, оптимизации, гидродинамического моделирования и способы использования различных типов нейронных сетей. Исследования основывались на анализе исторических, археологических, гидрологических данных саратовского Поволжья на протяжении последних четырёх столетий.
