All good but how does the snow develop & fall when all is below freezing?
Happens all the time, Warm air mass overriding a cold air mass, cools down, drops snow. Nothing mysterious about it. Or just cold air hitting a mountain range, rises, cools further and drops, yep, snow again. It's the same thing that causes snow anywhere, air mass cooling below the temp it can retain its moisture.
The important part is that the winter snow fall has to exceed the summertime melting.
I spent two winters in Alaska and I can assure you it snows when the temp is below freezing. I see the same thing every winter in my back yard.
Now why does the ice form? Snow compacts, doesn't melt and pressure and time do thier thing.
