CONT

Nous savons qu'il existe une assez bonne corrélation entre l'ablation et la température de l'air [...]. Mais la température de l'air décroît d'environ 0,5 par 100 m d'altitude. On peut donc calculer un ordre de grandeur de la variation maximum de l'ablation avec l'altitude [...] soit 100 cm/m.
