Re: APOD: Nacreous Clouds over Lapland (2023 Feb 09)
What is the importance of mountains in the creation of these clouds? I have read multiple times they help in the process, but considering the height of the clouds (15 - 25km) and compared to the usual mountains in these areas are just 1 - 2km tall (if even that) I just don't get how they would matter.
