Abstract

Even when the influence of climate on the geomorphological dynamics of mountain areas is well known, the ground and near-rock surface air thermal regimes of the highest altitude Cantabrian massifs still being poorly understood. This study, based on the examination of the thermal data obtained through the use of air and soil temperature dataloggers, aims to characterize the thermal regime of one of the most representative high mountain massifs of the Cantabrian Mountains: the Western Massif of the Picos de Europa. Results show the severe climatic conditions that prevail in the highest areas, where the snow cover lasts for 8 months on average, exerting an important insulating role of the soil. Thus, except on the uncovered rocky walls, the number of freeze-thaw cycles per year is low (0–16), with these cycles having a short duration and a low thermal amplitude. Significantly differences on annual thermal regimes have been confirmed; with two main phases (continued thaw phase and isothermal phase) and two minor transition phases at the ground, and only two main phases in near-rock surfaces (continued thaw phase and phase with a high number of FTCs).

欧洲皮科斯高山（西班牙西北部坎塔布里安山脉）的地面和近岩石表面空气热团

即使气候对山区地貌动态的影响是众所周知的，但最高海拔坎塔布连地块的地面和近岩石表面空气热状态仍然知之甚少。本研究基于使用空气和土壤温度数据记录仪获得的热数据，旨在表征坎塔布连山脉最具代表性的高山之一:欧罗巴丘陵的西部地块的热状态。结果表明，海拔最高的地区气候条件恶劣，积雪平均持续8个月，发挥了重要的土壤绝缘作用。因此，除了裸露的岩壁外，每年的冻融循环次数很少(0-16次)，这些循环持续时间短，热振幅小。年热状态的显著差异已得到证实;在地面有两个主要阶段(持续融化阶段和等温阶段)和两个次要的过渡阶段，在近岩石表面只有两个主要阶段(持续融化阶段和大量FTCs阶段)。

期刊介绍： Air, Soil & Water Research is an open access, peer reviewed international journal covering all areas of research into soil, air and water. The journal looks at each aspect individually, as well as how they interact, with each other and different components of the environment. This includes properties (including physical, chemical, biochemical and biological), analysis, microbiology, chemicals and pollution, consequences for plants and crops, soil hydrology, changes and consequences of change, social issues, and more. The journal welcomes readerships from all fields, but hopes to be particularly profitable to analytical and water chemists and geologists as well as chemical, environmental, petrochemical, water treatment, geophysics and geological engineers. The journal has a multi-disciplinary approach and includes research, results, theory, models, analysis, applications and reviews. Work in lab or field is applicable. Of particular interest are manuscripts relating to environmental concerns. Other possible topics include, but are not limited to: Properties and analysis covering all areas of research into soil, air and water individually as well as how they interact with each other and different components of the environment Soil hydrology and microbiology Changes and consequences of environmental change, chemicals and pollution.
