Geometry of patchy snowcovers / K. Shook, D.M. Gray, J.W. Pomeroy.

Title: Geometry of patchy snowcovers / K. Shook, D.M. Gray, J.W. Pomeroy.
Author(s): Shook, K.
Gray, D. M.
Pomeroy, J. W.
Date: [1993]
In: Eastern Snow Conference. Proceedings. ([1993]), Vol. 50th Annual Meeting ([1993])
Abstract: Influence of spatial variation in snow water equivalent (SWE) on areal snow-cover depletion and geometry of snow patches that form during ablation of shallow seasonal snow covers in open environments is discussed. Simplified snowpack ablation simulation is used to demonstrate that fractal structure of SWE causes soil and snow patches to possess fractal characteristics. This program is distributed grid-square model that uses synthetically generated snow cover and includes algorithm for approximating effects of local advection on melt. Fractal dimension(s) of snow patches produced by model agree closely with dimensions of natural ablated snow covers determined from analyses of air photographs.
