The TV weather presenters use a word ("Fern, ferd,) (?) winds?

This is the wind that comes over the mountains and hits the lee area.This causes adverse weather patterns. What is the word and where does it come from?

I think they were saying "Foehn" wind.





From wiki:





"A foehn wind or föhn wind is a type of dry downslope wind which occurs in the lee of a mountain range. It is a rain shadow wind which results from the subsequent adiabatic warming of air which has dropped most of its moisture on windward slopes (see orographic lift). As a consequence of the different adiabatic rates of moist and dry air, the air on the leeward slopes becomes warmer than equivalent elevations on the windward slopes. Föhn winds can raise temperatures by as much as 30°C (54°F) in just a matter of hours..."





Note: Use of the term implies that not only is the wind heating by downslope compression, heat is also added to the air from heat released from cloud condensation that is happening on the windward side. So the temp. on the leeward side is warmer because of those clouds than it would be if the wind were moving over the mountain and there were no clouds at all.





In southern California in the winter there are sometimes clouds banked up on the windward (north slopes) of the Tehachapis. When there is a wind blowing out of the north, the result can be temps in the 70s or 80s in L.A. while it's only in the 50s at Bakersfield, even though they are at similar elevations.
Reply:i think it's the foehn wind. It could be German from Föhn or Latin from favonius.
Reply:Foehn. I think it's German. There are similar winds all over the world with different names.
