Unformatted text preview: Infrastructure Snow Landscape patterns of tundra snow cover develop from wind distribution of snow rather than from spatial variability in precipitation Blowing snow can cause 1050% of the snowfall to be returned to atmosphere by sublimation of the windblown snow particles Increased vegetation (larger vegetation types) results in greater snow depth accumulation resulting in increased runoff from snow melt (w/no increase in precipitation) Change in surface albedo and energy exchange Increased snow thickness increases ground temperatures and decreases conductive heat flow to the atmosphere Shorter periods of snow cover (longer snowfree periods) lead to more solar radiation absorbed by land surface and longer growing season Questions?...
