 Forest snow cover dynamics in mountainous regions are highly dependent on the interactions between tree structure, terrain, and weather. Recently developed hyper-resolution models have allowed researchers to examine the effects of these factors on snow cover. The results from this study indicate that snow cover varies greatly depending on the specific combination of tree structure, terrain, and weather. This knowledge will be useful in developing more accurate models of snow cover in mountainous areas. This article was authored by G. Mazzotti, G. Mazzotti, G. Mazzotti, and others.
