Winds of this sort are also referred to as "snow-eaters" for their power to make snow and ice soften or sublimate swiftly.
Conversely, mainly because it descends around the leeward side, it moves from the lower-force location to a higher-force location at lessen altitudes. Compression resulting from this force difference ends in warming.
Nonetheless, Schubert is certain that tangible outcomes could positively change the way we deal with common weather conditions sensitivity. Until then, the only real consolation is you are not the sole a person which has a headache on foehn times.
