An Energy and Mass Model of Snow Cover Suitable for Operational Avalanche Forecasting

Abstract: ABSTRACT. A numerical model has been developed to simulate energy and mass evolution of snow cover at a given location , as a function of meteorological conditions: precipitation, air temperature, humidity, wind velocity, and incoming short-wave and long-wave radiation.This model, named CROCUS, was first tested on a well-instrumented field during a whole winter, showing its ability to simulate the important phenomena affecting the evolution of the snow layers: high temperature gradients, wetting, compaction, a… Show more

“…Despite the fact that estimating r b using Eq. More recently, estimates of r b have been produced using snow models that solve the surface energy balance and evolve a snowpack layer by layer (Brun et al 1989;Liston and Elder 2006;Lehning et al 2006), but these models require extensive meteorological input as well as the calculation of settlement of individual snow layers. A handbook for the NRCS field surveyors (Davis et al 1970) provides qualitative rules for adjusting the local mean snow density upward or downward depending on wind, exposure, thaws, and the day of the year.…”

“…For instance, the firn model initially suggested by Greuell and Oerlemans (1986) and developed further by several studies (e.g., Greuell and Konzelmann, 1994;Reijmer and Hock, 2008;Van Pelt et al, 2012) was successfully used in energy/mass balance studies on glaciers and ice sheets (e.g., Bassford et al, 2006;Reijmer et al, 2012;Van Pelt and Kohler, 2015). The CROCUS (Brun et al, 1989) and SNOWPACK (Bartelt and Lehning, 2002) models were originally designed for seasonal snow studies but were also successfully utilized for thicker snow, firn and ice packs (Obleitner and Lehning, 2004;Fettweis, 2007;Gascon et al, 2014;Lang et al, 2015).…”

“…SURFEX is an atmosphere to surface coupling model, with ISBA (Interactions between Soil, Biosphere, and Atmosphere) being the land surface scheme (Noilhan and Mahfouf, 1996). The Crocus model (Brun et al, 1989) is the most detailed of three snowpack models embedded in the ISBA routine. It was classified in the group of "most complex snow models" by the Snow Models intercomparison project (Etchevers et al, 2004).…”
