6. One paragraph description of your model (e.g. abstract from report or
   paper);

A one-dimensional model has been developed to simulate time series of
snow cover in mainly intense cold regions. This model can calculate
the profile of snow temperature, density and liquid water content using
meteorological data as input. The model structure is simple having snow
layers with same thickness; the treatment of liquid water flow and albedo
is very simple. Effective temperature gradient is introduced to consider
depth hoar, which is frequently observed in intense cold regions.
Using this parameter, we can incorporate the change of thermal conductivity
and compactive viscosity coefficient by depth hoar formation. Moreover,
the ratio of snow amount to rain amount is given as a function of wet-bulb
temperature.
