Natural Prerequisites of Changing the Vegetation Cover of Ribbon Forests on the Territory of Altai Krai

The article presents the study results of changes in the plant cover of ribbon forests of the Priobsky Plateau during the Holocene. According to satellite imagery data, a change in the role of different types of vegetation cover, corresponding to the current environmentally friendly conditions of the steppe and forest-steppe zones has been established.

Features of the Transboundary Rivers of Central Asia (on the Example of Kyrgyzstan)

The article describes the current situation of water resources in Central Asia (on the example of Kyrgyzstan) which recently caused a number of national and international meetings, consultations, and conflicts. The issue becomes even more acute when they are of a transboundary nature. In this regard, it is necessary to implement an integrated approach in the management of water and energy resources of transboundary rivers.

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

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.

Intraannual and interannual changes in clouds in Ufa

The study of cloud cover and its characteristics (quantity and forms) is of practical interest, especially for large cities. Cloud cover, having a dual effect (albedo and greenhouse), is an important factor in the formation of the thermal regime in the conditions of global climate change. This article presents the results of the analysis of daily, annual and long-term changes in the cloud cover regime in the city of Ufa(Republic of Bashkortostan). Urgent data from long-term observations of clouds (1966–2020) were used for the analysis.

Evaluating the statistical significance of air temperature changes in the Northern hemisphere by statistical methods

The analysis of changes in the near-surface air temperature of the Northern Hemisphere is given. To identify years in which there was a violation of the series homogeneity, the stepwise trend method was applied using Kolmogorov statistics. It is shown that the identified homogeneous climatic intervals basically correspond to the natural climatic periods of the state of the Earth’s climate system.

Assessing the continentality index of Western Siberia against the background of regional climate change

Quantitative assessment of the territory continentality is an urgent task, because in the conditions of climate change, the index of continentality can be taken into account when developing geographical forecasts of landscape development. The purpose of this study is to assess the change in the index of continentality of Western Siberia in the conditions of the current trend in climate development. The statistical series of observations on seven meteorological stations in Western Siberia served as the information base of the study.
