Ben, en fait, j'ai pas encore pas trop compris si c'est vrai ou pas: http://www.newton.dep.anl.gov/askasci/wea00/wea00181.htm Dans la même page: "Strong winds contribute to increased melting (or sublimation) of the snow by rapidly removing water vapor from the snow surface, allowing drier air to come along and thereby remove more water vapor." "In most cases stronger winds with above-freezing temperatures will hasten melting, due to the mixing of the water vapor just above the snow surface with drier air higher up" Et finalement: "Temperature (both air and ground), relative humidity, wind speed (can work either way)," Donc, fouille moi!
