Coeur dâAlene sits on a small spit at the north end of a large lake of the same name. The setting is decidedly attractive, with lake views on three sides of downtown and mountains on all sides looking south. The mountains are densely forested with fir trees, while trees in the immediate area of the town are sparse.
Each hemisphere has two primary jet streams â a polar and a subtropical. The polar jet streams form between the latitudes of 50 and 60 degrees north and south of the equator, and the subtropical jet stream is closer to the equator and takes shape at latitudes of 20 to 30 degrees.
Jet stream. Jet streams are fast flowing, narrow, meandering air currents found in the atmosphere of some planets, including Earth.[1] On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Their paths typically have a meandering shape.
