Hi all,
Sorry this may seem like a basic question given that there is much information already online. However, I'm trying to figure out in which direction the Foehn Wind acts over the Swiss Alps - some sources state that the warm winds descend on Europe, having released their moisture on the southern mountain slopes. However, others state the opposite; the warm winds descend on Italy (South of the Alps), implying that the moisture is released on the northern side of the Alps. Or does it switch between both directions?
I'm trying to figure out how this affects, in particular, the Rhone Glacier in the Swiss Alps - a glacier on the southern side of the Alpine range. Is the glacier subject to the warm foehn winds?
Here are two sources which state opposing views:
Warm air descends on the Italian slopes: http://www.eniscuola.net/en/argomento/air-in-motion/winds/the-foehn-wind/
Warm air descends on Central Europe: https://en.wikipedia.org/wiki/Foehn_wind
I'm assuming that it may be a mix of both directions, if so, does this vary seasonally? Which is more predominant?
Thanks in advance, this is my first time properly having to consider local meteorological conditions and I'm currently not getting very far!

Personally(in a 172) Iβve had an incident where we lost comms and vertical/horizontal guidance while on final in imc with low ceilings and it took me a probably 5-10seconds to decide to go missed. Some of the scariest seconds of my life not knowing where we were or if we were about to crash. Kept a level head proceeded to the missed approach point and figured it all out, fixed what was going wrong went around again and landed.
Probably pretty mild compared to some of your stories. Interested in knowing what your scariest imc incident was?
Extreme weather in Argentina with storms, blizzards, intense cold and heat above 40ΒΊC in the country today and in the coming days. A series of weather systems will bring radically different atmospheric conditions in the different provinces of the country throughout this second half of the week with a radically different scenario between the South and the North of the country.

A series of areas of low atmospheric pressure will act in southern South America and off the coast of Chile in the South Pacific. At the same time, a cold front will advance in central Argentina and another in Chile. And in Northern Argentina, an area of low thermal pressure will favor very intense heat. This series of synoptic scale systems will be responsible for generating diverse phenomena and in some cases severe weather.
INTENSE SNOW The action of several low pressure centers in the South of the continent and close to Chile will bring instability in the Andes. During the weekend, snow has already returned to several points in the Argentinean and Chilean Andes with accumulations of up to 20 cm to 30 cm.
With the prospect of successive systems of instability in Chile and Patagonia, even greater accumulations are expected and may even reach meters in the highest parts of the mountains.

Abundant snowfall precipitation arrives late. While it snowed heavily in southern Brazil at the end of July, famous ski resorts in Argentina closed their slopes due to lack of snow. The Andes so far have the lowest snow cover in 50 years. July was above average in the south of the continent. The cold and snow from Argentina, however, will not advance to the south of Brazil in the short term. The temperature should drop next week, but not too intense cold is expected.
WIND ZONDA Areas further west in Argentina, in the Cuyo region, such as Mendoza and San Luis, should face Zonda wind with the instability in the mountain range and on the Chilean side. Winds near or above 100 km/h of dry and hot wind are expected in the region, which should bring tree falls, vegetation fires, and power outages.
The Zonda is a typical western Argentinian wind, characterized by its persistence and intense gusts. It is very hot and extremely dry, often reducing the relative humidity to below 5% to 10%. The Zonda descends from the Andes Mountains and its predominant direction is West.
It usually occurs when there is instability on the other sid

For context I'm a Refuse Driver (Garbage man) & today I was on food waste. After I'd tipped I was checking the wagon for any defects when I spotted a lone pea balanced on the lifts.
I said "hey look, an escaPEA"
No one near me but it didn't half make me laugh for a good hour or so!
Edit: I can't believe how much this has blown up. Thank you everyone I've had a blast reading through the replies π
