Document Summary
As that air rises it cools, vapor may condense as a consequence, might get cloud and preceipitation. Sometimes air flows down, sinks down the leeward slope (slope facing away fro(cid:373) the (cid:449)i(cid:374)d). As it des(cid:272)e(cid:374)ds it (cid:449)ar(cid:373)s. as air (cid:449)ar(cid:373)s, its relati(cid:448)e hu(cid:373)idit(cid:455) de(cid:272)reases. Sometimes the diagrams show, all the air is called chinook wind. To be really precise, it actually develops at the base: a(cid:374)d there"s significant warming. For every 1000m it warms up 10 degrees celsius. This warming caused by the chinook at the base can be extreme and rapid. So, in january of 1964, alberta experienced a chinook, and temperatures rose 21 degrees in one hour. Chinooks have been reported greater than 100km/hr. can be hurricane for us: so it"s al(cid:271)erta, espe(cid:272)iall(cid:455) souther(cid:374) al(cid:271)erta (cid:449)ith its pro(cid:454)i(cid:373)it(cid:455) to the (cid:373)ou(cid:374)tai(cid:374)s that e(cid:454)periences chinooks. Similar winds occur elsewhere but they have diff names. European alps goes by the name of fern.
