A microclimatic profile between the Snake River Canyon and Clearwater Mountains, Idaho; Research technical completion report, project A-010-IDA Item Info

Temperature and relative humidity records have been kept at a maximum of 18 sites, and precipitation records at 8 sites, along a 75-mile profile between Wawawai, Washington, elevation 675 feet in the Snake River Canyon, and Crater Peak, elevation 6400 feet in the Clearwater Mountains, Idaho. Most distinctive microclimatic feature is the extreme development of nocturnal temperature inversions during summer and early autumn. Mean inversions between non-contiguous hilltops and bottomlands may reach 20 to 30 degrees. Greatest recorded on a specific day has been 42 degrees. Mean temperatures, length of frost-free season, nocturnal relative humidities, natural vegetation, and land use are all strongly influenced by these inversions. None of the six official Weather Bureau stations in the vicinity of the profile is located to show these inversions. Diurnal temperature and relative humidity patterns differ greatly at individual sites along the profile and are analyzed and compared. Precipitation normally varies by a factor of at least 3 1/2 along the profile, but may reach several times this value during individual months. Maximum snow depths range from none at Wawawai to 14 feet at Lost Lake near Crater Peak during specific snow seasons.
