Windbreaks

Windbreak is effective to a distance of 20 times its maximum height; effectiveness decreases the further away you move from the actual windbreak.

There must be some movement of air through a windbreak or the wind eddies on the other side of the barrier. The principle is to create the equivalent of the forest edge, which will lift the wind. The windbreak can be shaped so it tapers at the ends, reducing wind velocity.

Most effective shape is a boomerang or parabola.

Find a way to "see" how the wind and eddies flow in our yard. Something smokey and video camera?
