Same as in Norwegian, then; perlemorskyer :)
I got some more information about the conditions required for them to appear in my area. It can happen when there's fairly moist air in the mountains to our west combined with gale force winds from the west pushing the moist air into the stratosphere (at 10-50 km altitude) causing clouds of ice particles to form (-15 to -50°C). The wavy form comes from the wind being "shaped" by the mountains, sort of a blueprint of the mountains. In addition the weather must be clear at lower altitudes and the time of day must be right (with the sun between 1° and 6° below the horizon).

Yes, it is. I don't think I've seen such clouds more than once before. That is, at least not under the right conditions - on a predominantly clear sky just after sunset so that the sun hits them at just the right angle.

Deep breath... Lenticular type II polar stratospheric clouds.

Not up on the ledge, no. I tend to stay away from the "touristy" spots even if they are massively spectacular such as Preikestolen. But yeah, I really should go there (off-season) some time. Then again, it's an 8 hour (non-stop) drive to a part of country where I normally have no other reason to go...
