Wind run is the total distance that the wind has traveled during a particular period of time in a particular direction.
Hmm.. I see - but I'm not sure I understand the graph. Is the Y-axis tenths of miles? If so, is the graph showing the distance the wind has traveled at a certain time (3:00pm, 5:30pm, etc.)?!?
I would think it would show the distance in a certain time
period (like 10min, 30 min, etc).
