<br />~ <br /> <br />· Because of the apparent favorable precipitation environment around <br />the Vail Ski' Area or the study's consistent method of under-estimating <br />precipitation amounts as indicated in the Snotel Precipitation <br />Evaluation, a similar adjustment was made to the Ski Area estimated <br />values. By making the adjustment of increasing the comparative Vail <br />estimate by 8.2%, the results derived from the Ski Area evaluation <br />would be consistent with the Snotel evaluation. This adjustment <br />decreased the overall seeding effect over the Vail Area from a 42% to <br />31.3% increase in precipitation amounts. <br /> <br />· For seeded weather systems with more Westerly wind directions (240 <br />deg. to 295 deg.), much of the precipitation increase is observed as <br />wetter snow densities rather than additional inches of snow. <br /> <br />· As the wind direction of a seeded weather system moving through the <br />region becomes more Northerly, the increased precipitation is observed <br />as additional inches of snowfall and snow densities became more <br />equal. These increases in snowfall amounts can range upwards to <br />around 40%. I <br /> <br />// <br />
