A simple steady-state orographic precipitation model is being tested using the topography of Colorado on a 10×10 km grid mesh. Model input requirements are vertical profiles of wind, temperature, and humidity at the upwind borders of Colorado. Model output consists of total precipitation at each point over any desired “assumed period of representativeness” of input atmospheric conditions. Summation of any desired number of runs is provided for. Model output is compared to snow course and precipitation data. Preliminary results are discussed.
