Thanks. Just a hypothetical question in respect to the length of time it would take for the wind to spin up, peak and wind down, over a point. As there is no "perfect storm" I understand the symmetry of the windfields. I found graphics for the question at Skeetobite. Even though they are old tracks.
Had I known Clark, Jason and some of the others were still here, I wouldn't have attempted to answer. They will always be more qualified for those questions.
