Interpreting orographic snowfall patterns
Winter precipitation in mountainous southwest Colorado was related to terrain slope and elevation by multiple regression. From a 12 season record of 15 daily precipitation stations, the study used only those days with ≥ .01 in. at ≥ one station. Days used were classed by mean 24 hour 700mb wind direction and speed. By class, each station's mean 24 hour precipitation was computed as was station slope over 8 distances. These precipitation values were correlated to elevation and to products of terrain slope X 700mb wind speed X 700mb mean saturation mixing ratio lapse rate. (Products are simplified ...
