Foehn wind to greater daytime radiative (solar) warming under foehn conditions. This type of warming is particularly important in cold regions where snow or ice melt is a concern and/or avalanches are a risk. Winds of this type are also called "snow-eaters" for their ability to make snow and ice melt or sublimate rapidly. This is a result not only of the warmth of foehn air, but also its low relative humidity. Accordingly, foehn winds are known to contribute to the disintegration of ice shelves in the polar regions. Foehn winds are notorious among mountaineers in the Alps, especially those climbing the
Antarctica Weather Danger Classification reaching Condition 2 based on windchill values of or below do happen. And reaching Condition 1 based on windchill values of or colder does occur. Antarctica Weather Danger Classification The weather in Antarctica can be highly variable, and weather conditions will oftentimes change dramatically in a short period of time. There are various classifications for describing weather conditions in Antarctica; restrictions given to workers during the different conditions vary by station and nation. An air temperature of or below would meet the criteria for Condition 2. And an air temperature of or colder would meet the criteria for Condition 1.
