Jan 20 2013
As I write this morning before dawn, the wind is whipping around the house as a winter storm approaches from the west.
If I was at the roof peak I’d be blown away. The wind is even faster up there (see red lines at top) where it converges to clear the house.
Outside my window on the downwind side, the air is swirling in updrafts like the turquoise lines at left.
I suppose I could find a few calm spots within the swirls if I went outdoors to experiment, but it’s not worth it. At particularly gusty moments I hear garbage cans rattle down the alley in the dark.
