The use of fractal geometry in modelling intercepted snow accumulation and sublimation / J.W. Pomeroy, R.A. Schmidt.
Title: | The use of fractal geometry in modelling intercepted snow accumulation and sublimation / J.W. Pomeroy, R.A. Schmidt. |
Author(s): | Pomeroy, J. W. Schmidt, R. A. |
Date: | [1993] |
In: | Eastern Snow Conference. Proceedings. ([1993]), Vol. 50th Annual Meeting ([1993]) |
Abstract: | In forests, interception of snow can store 60% of cumulative snowfall in midwinter and subsequent sublimation can return 30% of annual snowfall to atmosphere. Sublimation algorithm for single ice sphere and "exposure coefficient" which accounts for difference in surface area to mass ratios between intercepted snow and ice sphere allow calculation of sublimation rate in coniferous canopies. Fractal geometry provides means to calculate this exposure coefficient from diigitized photographs of snow-covered canopies. Intercepted snow is fractal and irregularity of its shape depends on location in canopy and age of snow. Fractal shape permits relationship between snow-covered area in canopy photographs and interception load. |
