Prevailing wind direction and the wind direction of greatest potential snow transport are needed to calculate the attack angle later.

The first table on the right gives the prevailing wind direction for each of the winter months, and the overall prevailing winter wind direction, 310°, or NW.
See a degrees vs. cardinal direction table.

The second table on the right gives the potential snow transport (Qupot). The direction of greatest snow transport is 310°, or NW.

The prevailing wind direction in therefore 310°, or NW.
