Short summary
Snow gliding is a key factor for snow glide avalanche formation and soil erosion. This study considers atmospheric and snow variables, vegetation characteristics, and soil properties, and determines their relevance for snow gliding. The soil moisture, the soil temperature, the liquid water content of snow, the phytomass of mosses, and the friction coefficient have major influence. However, further investigations may be focused on the freezing and melting processes in the uppermost soil layers.
