A Numerical model for assessing the influence of snow cover on the ground thermal regime

Note: / The purpose of this study was to develop and evaluate a numerical model for simulating the influence of seasonal snow cover on the ground thermal regime.The physical processes occurring within the snow pack and underlying ground, as well as at the surface, are reviewed from the viewpoint of their eventual inclusion in a practical numerical model. A finite difference heat conduction model suitable for long-term studies of the snow-ground thermal interaction is presented. This model incorporates a numerical prediction of density and temperature profiles within an evolving snow cover. Phase change within the ground is treated by a new numerical method which has important computational advantages over older methods.[...] / Cette etude avait pour but Ie developpement et l'evaluation d'un modele numerique pour la simulation de l'influence du manteau neigeux saisonier sur Ie regime thermique du sol.Les processus physiques rencontres dans Ie manteau neigeux et Ie sol sous-jacent ainsi quIa l'interface air-surface sont discutes et passes en revue dans l'optique restreinte de leur eventuelle inclusion dans un modele numerique. On presente ensuite un modele a conduction en differences finies qui convient pour les etudes de l'interaction thermique neige-sol a long terme. Le modele inclut un calcul numerique de l'evolution temporelle des profiles de densite et de temperature du manteau neigeux. Les changements de phase dans Ie sol sont traites par une nouvelle technique numerique avantageuse pour Ie calcul.[...]
