Abstract: Snow friction results from a mixture of processes. Usually the snow and ski surfaces are partially separated by melt water but, when too much water is present, the contact area and friction increase. Ski thermal conductivity and color are very important. Heat is generated by friction and solar radiation absorption and is conducted away by both ski and ice particles. The remaining heat generates melt water, which acts as a lubricant. The important processes operate, not at the air temperature, but at the ski base temperature, which is highly dependent on such things as snow-surface temperature, load, and speed.
