What type of climate does the Great Basin region in the western U.S have?
BSk (Dry Steppe cold) climate classification for most of the Basin in the Koeppen system. The climate is typical of middle latitude, semi-arid lands where evaporation potential exceeds precipitation throughout the year. There is no water surplus or stream originating in such a climate, and mean annual temperatures are under 64.4 degreesF (18 degrees C). Oases occur where highlands generate surface streams or springs. By the time air masses reach the Basin’s eastern edge they get another lift, creating extra moisture and highland climates that support Utah’s population corridor below. High-level, low-pressure systems affecting Utah weather at the precipitation maximums in spring and fall are often referred to as “Great Basin” or “Nevada” lows. Includes the Great Basin region of Nevada also.
