The first table on
the right gives the prevailing wind direction for each
of the winter months, and the overall prevailing winter
wind direction, 190 degrees, or S.
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 300°,
The prevailing wind direction
in this case should be taken as 300°, or WNW,
because, contrary to the modal direction from above,
it represents the direction of greatest snow transport
and is therefore more useful to the snow fence design.
