My Anemometer
This picture was taken through a (dirty) window on the 32nd floor of the Guardian Building in downtown Detroit.
The building shown is "150 W. Jefferson", a new-ish office building, built by Heller Manus Architects in 1989. Atop the tower of this "Post Modern" building are four flags mounted on 30 foot poles. These flags are visible for quite some distance, even from Windsor, Ontario, Canada, across the partially frozen Detroit River in the background.
Because the flags are at 90 degrees, we can estimate wind speed of greater than 22mph. On that gray, raw day, they were flapping furiously and were fully extended continuously, so the wind speed was estimated at 32-37mph. An anemometer would give more precise measurements, but when flags are in this position, it's too windy for me :-))
