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 Streams extended definition. Jets are fast moving ribbons of air high up in the atmosphere. They are responsible for transporting highs and lows. They affect precipitation and temperatures, and they mark boundaries between massive air masses.
