| FOEHN WIND
this occurs when a deep layer of prevailing wind is forced over a mountain range. as the wind moves upslope, it expands & cools, causing water vapour to precipitate out. this dehydrate air then passes over the crest & begins to move downslope. Foehn winds can rise temperature by as much as 30 degree C , 54 degree F in just a matter of hours.
EFFECTS :
winds of this type are called "snow-eaters" for their ability to make snow melt rapidly. this ability is based not only on high temperature, but also the low relative humidity of the air mass. Foehn winds are often associated in popular mythology with illness ranging from migraines to psychosis.
the name Foehn came from German, originated in the alpine region.
