haha good question, id say technically if you are standing right on the true north pole, than the wind is certainly not coming from true north ( unless maybe its a straight downdraft ??! )
However, i think what they actually do is take a map of the area and orient it so that 0 degrees longitude is pointing "up" and overlay a grid on top. Zero longitude then marks the north and south directions, while 90 degrees clockwise from north (90E) is grid east, 270 is west, and so on.
so, while it is perfectly sensible to speak of north wind at the north pole... the definition is practical, and not founded in any truth about the directions of the compass.

if you are at the north pole according to the lines of latitude and longitude the than the wind would always blow from the south because every direction is south from there. they probably measure it in degress out of 360 starting at the prime meridian would be 0. then you can raise a whole other question if you wanna talk about magnetic north.
