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.

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.

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.

Anomalous phenomena and geoecological situation in the Russian Far East

Authors: Skrylnik G. P.

The development of the geosystems of the Russian Far East proceeds under the enormous but contradictory in nature double influence of the continent and the ocean and is carried out through the atmosphere. The goal is to characterize hazardous natural phenomena depending on the differentiated natural tension of the Far East (from maximum in the south to moderate in the north), often causing disasters and creating tense levels of the geoecological situation in general. The article presents comparative-geographical, geophysical, informational methods, as well as author’s development, etc.

Spatial planning at the macro and micro levels: Problems of taxonomy and polarization (on the example of the Volga-Ural macroregion)

Authors: Preobrazhenskiy Y. V.

The issue of spatial planning includes the subject of taxonomy. It seems that it is necessary to switch to the practice of planning, in addition to the meso-level (subject of the Russian Federation), at two taxonomic levels: the macroregion and the economic microdistrict. To do this, the article identifies the main properties of these formations. On the example of the Volga-Ural macroregion the properties of integrity, complementarity and connectivity are analyzed. The idea of using micro-level nodal districts (economic micro-districts) is substantiated as objects of spatial planning.

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

Authors: Sheshnev A. S., Majeed D., Reshetnikov M. V.

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.

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

Authors: Bogdanov M. B., Morozova S. V.

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.

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

Authors: Bogdanov M. B., Chervyakov M. Y.

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.
