Sailboat wind indicators mounted at on 3-foot intervals on a flagpole at the east end of Fort Mason illustrate how the laminar flow of wind changes with the height. This variation is often more complex and dramatic than expected. Along the San Francisco shoreline, for example, the difference of only 20 feet in altitude may mean a 90 degree difference in the wind direction.
This is part of the Outdoor Exploratorium. It was created in partnership with GGNR (Golden Gate Recreation Area) and the Fort Mason Center. The interactive exhibits are designed to help visitors notice the subtle phenomena of the outdoors.
The Exploratorium is our museum of science. It was founded in 1969.

Having been to SF a few times I can testify that there’s nothing subtle about the winds there! 🙂
Wow, how interesting! I’m amazed at the creativity and thought in this! Love that up the pole shot!
