Snow collecting on opposite side of wind

Where I'm sitting I can see the front of my car. Relative to that the snow is blowing from right to left, but the 'right' side of my bonnet (passenger side) is clear with snow piling up on the 'left'

Seems wrong, what gives? Well the right side of my car is in the wind so any snow that lands there is likely to get blown off before it sticks. The left side is out of the wind so the snow sticks and then more snow can stick to that and so on.
