This paper attempts to provide some practical suggestions for graphical and statistical methods used to describe interannual and seasonal variations of the snow‐cover amount. Essentially two techniques are developed: (i) the ‘probability calendar’, which gives for each day of the cold season (December to May) information on the probabilities of observing some given thickness of the snow‐pack, and (ii) ‘probability charts of evolution’, which give probabilities for the evolution during the snow‐melt period of a snow‐pack having a given thickness at a given date. In order to build these charts we develop statistical models of the melting and compaction of snow using standard meteorological data.
