We present in this short paper a simple and computationally efficient
numerical model that depicts a column of sublimating, blowing snow.
This bulk model predicts the mixing ratio of suspended snow by
solving an equation that considers the diffusion, settling
and sublimation of blowing snow in a time-dependent mode. The bulk
model results compare very well with those of a previous spectral
version of the model, while increasing its computational efficiency
by a factor of about one hundred. This allows the integration of the
simplified algorithm into more sophisticated mesoscale models to
estimate the thermodynamic tendencies arising from blowing snow
sublimation and the effects of this process to the snowcover and
the atmospheric boundary layer.
