二十世纪末至二十一世纪中叶的32年降水变化是investigatedusingregionalclimatemodelsimulations providedbytheNorthAmericanRegionalClimateChange评估计划(NARCCAP)。这些模拟总体上表明，科罗拉多州的大部分地区和毗邻州的边境地区未来的夏季将更加干燥。尽管从第50个百分位数到第95个百分位数，所有模型中都出现了increaseinthesurfacespecifichumidity.Thedomain-averageddecreaseindailysummer降水，但对于最极端(前1%)事件的变化迹象，没有明确的一致意见，但降水量仍会减少。
Precipitation changes between 32-yr periods in the late twentieth and mid-twenty-first centuries are investigatedusingregionalclimatemodelsimulations providedbytheNorthAmericanRegionalClimateChange Assessment Program (NARCCAP). The simulations generally indicate drier summers in the future over most of Colorado and the border regions of the adjoining states. The decrease in precipitation occurs despite an increaseinthesurfacespecifichumidity.Thedomain-averageddecreaseindailysummer precipitationoccurs in all of the models from the 50th through the 95thpercentile, but without a clear agreement on the sign ofchange for the most extreme (top 1% of) events.
