Foehn, on the other hand, is mainly known for causing headache:

But the patriot in me would have rejoiced, and it would have been a perfect fit for Maemo for the "how the f#%§ do I pronounce that?" factor.

That's easy: Föhn. As in Föhn.

(BTW, this leads us straight on to the J-Wind: Jauk. That's what people in Carinthia call the Foehn that comes down from the Karawanken.)

Föhn is a warm wind falling from the alps in the southern part of Germany. And yes, it's known to cause headache for many people. So why not call a hacker edition "Föhn" as it will cause headache to many people, too.

For G, there still would be Ghibli, now that Gregale has already been taken by OS 2006.

Ghibli's a no-go, I'll just think of Miyazaki films.

Indeed. How about Nausicaa for N?
Kaze no tani no Nausicaa. Not a wind, but related to the valley of winds.

When even lolcats can spell Fremantle correctly, you've got to feel bad for those who can't.

And let's not forget http://en.wikipedia.org/wiki/Category:Winds for a bundle

My local 'K' wind missing from your list is Koshava: http://en.wikipedia.org/wiki/Ko%C5%A1ava_(wind))

PS. As for Föhn supporters, Chinook is I believe just a different name for the same wind

eiffel: I think you need to edit your post and make "mistral" and "sirocco" bold as well... (Unless I'm completely missing your logic...)

Chinook is a wind from Western Canada.

Every now and then, in the depths of winter, the Chinook will blow and devour the snow. It is said that the Chinook works so fast that, if you try to get home when you notice the wind blowing, the front of your sleigh's runners will be on snow, and the back ends of your runners will be dragging in the dirt.
