The southernmost portion of the Great Basin is the watershed area of the Laguna Salada. The Great Basin's longest and largest river is the Bear River of 350 mi (560 km), [10] and the largest single watershed is the Humboldt River drainage of roughly 17,000 sq mi (44,000 km 2).
The Great Basin and Columbia Plateau (the Intermontane Plateaus) are arid or semiarid regions, with high summer temperatures in the 90s to occasionally over 100 at lower elevations (e.g. at Boise, Idaho), with annual precipitation averaging less than 15 inches (380 mm) as a result of the rain shadow of the Sierra Nevada and Cascades.
Eastern Oregon falls into the cold semi-arid climate (or BSk type), which features drier weather. West of the Cascade Range, winters are chilly with frequent rain and occasional snow. Temperatures can get very cold, but only occasionally, as the result of Arctic cold waves. The high desert region of the state is much drier, with less rain, more ...
Santa Ana winds and, their Bay Area cousin, the Diablo winds occur when air from a region of high pressure over the dry Great Basin region of the U.S. flows westward toward lower pressure located ...
Since the Great Salt Lake never freezes, the lake-effect can affect the weather along the Wasatch Front year round. [23] The lake-effect largely contributes to the 55 inches (140 cm) to 80 inches (200 cm) annual snowfall amounts recorded south and east of the lake, [ 24 ] with average snowfall amounts exceeding 600 inches (1,500 cm) in the ...
Buckingham noted that the next storm is expected to be focused farther south as it enters the West Coast to bring rain and mountain snow to Central and Southern California, the Great Basin and ...
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
The Great Basin Desert is part of the Great Basin between the Sierra Nevada and the Wasatch Range in the western United States.The desert is a geographical region that largely overlaps the Great Basin shrub steppe defined by the World Wildlife Fund, and the Central Basin and Range ecoregion defined by the U.S. Environmental Protection Agency and United States Geological Survey.
