Climate of Mountains of Colorado <br /> Colorado is best known for its mountains. They occupy less of the area of the state <br /> than many realize, but they profoundly impact the climate of the entire region. The <br /> main feature of the mountainous area of central and western Colorado is the dramatic <br /> differences in climate over short distances. With elevations ranging from below 7,000 <br /> feet in the lower mountain valleys to more than 14,000 feet on the highest peaks, all <br /> aspects of the climate are affected: temperature, humidity, precipitation and, of <br /> course, wind. <br /> In general, temperatures decrease with elevation. Summer afternoon temperatures <br /> consistently decrease about 4-5 degrees F per thousand feet. Typical July afternoon <br /> temperatures are in the 70s and 80s in the lower valleys but are only in the 50s and <br /> 60s in the higher mountains. But elevational temperature changes are often masked by <br /> temperature inversions especially at night and during the winter. Cold air is more <br /> dense than warmer air and collects in some of the mountain valleys. On clear nights, <br /> especially during winter when the ground is snow covered, strong temperature <br /> inversions form. Under these circumstances, the coldest temperatures are found near <br /> the center of these high valleys, while temperatures in the high mountains are <br /> considerably warmer. The San Luis Valley around Alamosa, the Gunnison Valley <br /> around Gunnison, the Eagle Valley, the Fraser valley and the Yampa Valley near <br /> Steamboat Springs all can be very cold on clear winter nights. Subzero Fahrenheit <br /> temperatures are commonplace in these areas and the most winters see at least a few <br /> nights with temperatures dropping below -30°F. Even in summer, temperatures can <br /> dip below freezing. Under extreme conditions, temperatures have dipped as low as - <br /> 60°F at Taylor Reservoir and -61°F along the Yampa valley in northwestern <br /> Colorado. Such cold temperatures are rare but demonstrate the extremes that mountain <br /> weather patterns can produce. Fortunately, these cold temperatures are nearly always <br /> accompanied by light or calm winds. <br /> It is quite a different story on the mountain peaks. Strong winds are common at <br /> elevations above tree-line (approximately 11,500 feet) throughout the winter months <br /> and can exceed 50 to 100 mph in exposed locations. Outdoor adventurers must be <br /> prepared for the most extreme of conditions year round, but particularly in winter and <br /> spring. <br /> Wind patterns in the mountains are almost always controlled by topography. <br /> Mountain-valley circulations are common with winds often blowing up the valley <br /> from lower to higher elevation during the day reversing and blowing down the valleys <br /> at night. The mountains form a substantial block to regional air motion causing winds <br /> in most valleys west of the Continental Divide to be very light, especially in fall and <br /> winter, while winds along and east of the crest of the Continental Divide are much <br />
