'Superior' Mirage

Uploaded by: katy99780

Friday March 7, 2014

Tok, AK (Current Weather Conditions)

Caption: Not a very clear image, but it does show a 'superior mirage', a mirage that seems to bring the ground upwards. In reality, there is no hill in the roadway ahead of me. (just mountains!) :)

Common in the Arctic and cold regions, this kind of superior mirage occurs when a layer of cold dense air is trapped beneath a warmer, less dense layer. In this case, the layer of cold air was -31 F.

The 'real' thing mid-morning today, after an inversion disappeared.

Thank you very much James, Julia, Max, Jean and Eileen!

I'll see if I can get a better photo today, both of the inversion, and when the inversion warms and disappears. -31 this morning too.

The gorgeous snow-covered mountains stand out - something most of us don't get to see. To me, it's a superior photo. Thank you.

Also enjoy the deep-green healthy looking trees in the photo you added to Comments.

Very interesting picture and caption. I always associated mirages with heat. Maybe that's because of where I live (Florida).

Thanks Eileen, Mark and Ivan.

I can't find anything very good Ivan, it seems I mostly take shots of this view only when there's an inversion.

Here's one without, not very good. Maybe I'll take a 'flat' one, just for reference, tomorrow.

Wow, it looks so convincing. Do you have a photo taken when there wasn't a mirage?
