Snow and Sand Erosion Explained
- EN - FR
Scientists at EPFL and SLF describe with precision how snow and sand surfaces erode when exposed to wind. Their description can contribute to better predictions of dust emissions from deserts and snow transport in Antarctica, and can be adapted to other planets. Wind and water transport a multitude of particles with them, leading to erosion or deposits, like dust emissions from the Saharan desert that can reach Europe and snow transport that can.. block traffic. Francesco Comola and Michael Lehning from EPFL and SLF accurately describe how wind flow affects a generic surface of non-homogeneous particles, like snow or sand, using a new theory that will one day help improve weather predictions. The results are now available in Vol. No.
