Abstract

The annual frequency of freeze-thaw cycles (AFFTC) on the Earth's surface affects many natural components: landscape, ecosystems, engineering infrastructure, etc. However, the nature of changes over time and the driving forces of the AFFTC for the territory of Russia today remains largely undocumented. Based on an analysis of archival meteorological materials from more than 500 meteorological stations and posts, including those dating back to the last century, the article proposes zoning schemes for individual regions of Russia according to AFFTC data. Using a statistical tool based on the phenomenon of spatially stratified heterogeneity (SSH), the influence of various factors (air temperature, precipitation, etc.) on AFFTC was assessed. In the study area from 2005 to 2023, in comparison with 1980, areas with a higher value of AFFTC are shown to have increased. It is also confirmed that latitude and altitude are the variables with the greatest explanatory power, i.e., having the greatest influence on the AFFTC. Altitude above sea level has a particularly significant impact on the AFFTC in the range of 541–1850 m when the average annual air temperature is in the range of −3.9 … −0.8 °C. The observed formation of AFFTC features at the regional level appears to have a universal character and can thus be applied to solve a wide range of problems in assessing and forecasting climatic conditions, explain engineering-geological properties and predicting the degree of cryogenic transformation of soils with various structural connections, as well as forming a basis for recommending measures for environmental management and developing corresponding engineering construction standards.

俄罗斯冻融循环年频率的时空变化

地球表面冻融循环（AFFTC）的年频率影响着许多自然成分：景观、生态系统、工程基础设施等。然而，随着时间的推移变化的性质和今天俄罗斯领土的AFFTC的驱动力在很大程度上仍然没有记录。基于对来自500多个气象站和站点的档案气象资料的分析，包括那些可以追溯到上个世纪的气象资料，文章根据AFFTC的数据提出了俄罗斯各个地区的分区方案。利用基于空间分层异质性（SSH）现象的统计工具，评估了气温、降水等因素对AFFTC的影响。2005 - 2023年研究区AFFTC值较高的区域与1980年相比呈增加趋势。也证实了纬度和海拔是解释力最强的变量，即对AFFTC的影响最大。在541 ~ 1850 m范围内，当年平均气温为−3.9 ~−0.8℃时，海拔高度对AFFTC的影响尤为显著。在区域层面观测到的AFFTC特征的形成似乎具有普遍性，可用于解决气候条件评估和预测、工程地质性质解释和预测各种结构连接土壤的低温转化程度等广泛问题，并为环境管理措施的建议和制定相应的工程建设标准提供依据。

期刊介绍： Physics and Chemistry of the Earth is an international interdisciplinary journal for the rapid publication of collections of refereed communications in separate thematic issues, either stemming from scientific meetings, or, especially compiled for the occasion. There is no restriction on the length of articles published in the journal. Physics and Chemistry of the Earth incorporates the separate Parts A, B and C which existed until the end of 2001. Please note: the Editors are unable to consider submissions that are not invited or linked to a thematic issue. Please do not submit unsolicited papers. The journal covers the following subject areas: -Solid Earth and Geodesy: (geology, geochemistry, tectonophysics, seismology, volcanology, palaeomagnetism and rock magnetism, electromagnetism and potential fields, marine and environmental geosciences as well as geodesy). -Hydrology, Oceans and Atmosphere: (hydrology and water resources research, engineering and management, oceanography and oceanic chemistry, shelf, sea, lake and river sciences, meteorology and atmospheric sciences incl. chemistry as well as climatology and glaciology). -Solar-Terrestrial and Planetary Science: (solar, heliospheric and solar-planetary sciences, geology, geophysics and atmospheric sciences of planets, satellites and small bodies as well as cosmochemistry and exobiology).
