What Does A Windbreak do?

 

A windbreak slows the wind in one place by deflecting it to another. The best windbreaks produce a zone behind the windbreak which will have wind of about a quarter of the speed. For a 50ft high windbreak this zone will extend about 250ft downwind. From 250ft to 500ft the windspeed will increase up to about half that of the incoming wind. Beyond that windspeeds increase quickly.
