Pluriannual thermal behavior of low elevation cold talus slopes in western Switzerland
The internal and reversible mechanism of air circulation (chimney effect) throughout a porous debris accumulation acts as an efficient advective conveyor of heat, which strongly influences its thermal balance during the whole year. Ground temperature monitoring carried out at eight sites located bel...
