Seeing those fantastic shapes makes me wonder...
Wouldn't it be interesting to have access to a computer program that would
simulate how wind driven snow builds up on a 3D object. This goes beyond
mere flow line visualization. And it goes beyond showing velocity and
pressure distributions in 3D.
For sure it would take a lot of computational power. And there would be the
matter of specifying how the snow would accumulate, "stick" together in
moving air.
I have come across references to snow drift prediction software used in
archetecture and mechanical science applications. So, maybe the capability
already exists in the halls of academe.
But I would think that a large part of snow drifts is the flakes sort of
"falling out of solution" as opposed to "sticking-to on the way by"
