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.
Its altitude is generally at the 250-300 hPa level. A Jet Stream can be several thousand miles long, but only a few hundred miles wide and a few thousand feet in depth. The winds in a Jet Stream are not constant, nor is the direction always west-east.he Sub-tropical jet Stream is located entirely within the tropical air mass and is not associated with any surface fronts. Its location is less variable than the Polar Jet Streams, and its altitude is at around the 200 hPa level.
