Stratification of the atmosphere: a subfreezing layer in the lower atmosphere is required for precipitation to reach the ground in solid formĬooling rate: high snowfall rates occur where snow is rapidly cooled, e.g. Water vapor content governed by the Clausius-Clapeyron-relationship: the warmer the air, the more water it can hold and hence the more precipitation can form Snowfall varies substantially with latitude and altitude, where the primary factors determining snowfall rates are: The most important accumulation processes are listed below in order of their relative importance: Accumulation processes #Īccumulation processes are all processes that add snow or ice to a glacier (surface). The mass balance is the result of several processes that either add mass to the glacier ( accumulation) or remove mass from the glacier ( ablation). The glacier images are taken from the open glacier graphics on OGGM-Edu, made by Anne Maussion, Atelier les Gros yeux. From oggm_edu import Glacier, MassBalance, GlacierBedĬopyright notice: the following sections are heavily based on the book “The Physics of Glaciers” by Cuffey and Paterson, (2010).
