<br />21 <br /> <br />warning and prediction. Model results were summed over the October 15- <br />April 30 period for several years to test its ability to reproduce <br />climatological precipitation patterns. Rhea tested his results versus <br />the October-April precipitation analysis on the 1931-1960 maps. Results <br />of this test showed a very good comparison at higher elevationsngood <br />enough to justify the operational use of the model. <br />The model-generated winter precipitation pattern was carefully <br />examined during the process of generating the new 1951-1980 map. While <br />model resul ts were not used di rectly in the mappi ng process, they were <br />used to give an indication of precipitation in data sparse areas. For <br />example, model results were used to hel p justify small increases of <br />annual average precipitation on portions of the Uncompahgre Plateau <br />where data are nearly nonexistent. The model al so suggested that <br />portions of the Grand Mesa, the Flat Top mountains, and the Park Range <br />east of Steamboat Springs may receive more winter precipitation than <br />previously thought. <br /> <br />~ <br />
