Wind shields are necessary to provide the best "catch" of winter precipitation. Various wind shield designs have been used throughout cold climate regimes. In this study, sonic anemometers were used to evaluate the reduction in turbulence as compared to "free stream" measurements unobstructed by any obstacles. Reduction in the mean velocity field at the gauge were found to correlate with the "catch ratio", defined as the measured precipitation fraction relative to a "standard". .
