Abstract
An apparatus for determining wind characteristics, including compass direction and inclination to the horizontal, includes a hemispherical frame on which a plurality of resonant chambers are mounted, defined by tubes with axes passing through the center of curvature of the hemisphere. One end of each tube is closed, and the end toward the center of curvature is open. Wind blowing across openings appropriately orientated will cause air within the chamber to resonate and create a sound. Each tube has a sound detecting unit for producing a signal when the chamber is resonating, and a computer receives the signals and determines from them the direction of the wind.
