Thermal regime of three low elevation scree slopes in central Europe
Abstract External air temperature (EAT) and the interior temperature of the talus (IT) were measured for one year at two low elevation scree slopes in the Sudeten Mountains, central Europe. Similar measurements were made at an ‘ice‐cave’ beneath a talus and supplemented by cave‐floor temperature (CG...
