While at work today, I was looking outside and noticed the snow was blowing in one direction, but near the windows and building, it was going in the opposite direction, sort of diagonal to where it was blowing elsewhere. Is this caused by the way air is flowing around the building? Or some sort of heat soak effect from the building itself causing the air close to it to cause a change in direction of the snow?
In: Physics
Air cannot go through buildings. Thus it must change direction to avoid the building. Snow tends to move at roughly the same speed as the air around it, so the snow must also mostly go around the buildings.
