Long-term soil temperature dynamics in the Sierra Nevada, Spain

Abstract

These were recorded mostly in spring and autumn in the first 50. cm depth of the soil, ranging from 9.8. days (at 2. cm) to 3.7. days (at 50. cm).However, the inactivity of solifluction landforms suggests that the combination of present-day soil temperatures together with moisture conditions is not favorable to promote solifluction activity in the periglacial belt of the Sierra Nevada.Future climate scenarios point to a temperature increase and precipitation decrease in the area, which would entail deeper but shorter frozen soil layers. These conditions would not be favorable for active periglacial slope processes in the Sierra Nevada.
