The mesosphere is cold enough to freeze water vapor into ice clouds. You can see these clouds if sunlight hits them after sunset. They are called noctilucent clouds.
Miðferan er nóg køld at frysta damp til ísskíggj. Hesi skíggj síggjast, um sólstrálur raka tey eftir sólsetur. Tey kallast kvøldarskýggj.
