In California there are fivewell marked factors operating to control climaticconditions. Of these perhaps the most important isthe prevailing drift of the surface air from west to east,common to temperate latitudes, but marked in thissection of the American continent. In this great aerialstream are the lesser currents induced by the eddiesand counter-eddies familiarly known as lows andhighs. It has been found that these disturbancesfor the most part drift east along a line north of Cali-fornia and this is the chief reason why the weather ingeneral is less changeable than in regions nearer thestorm tracks or paths of greatest storm , the proximity of the Pacific Ocean, a greatnatural conservator of heat, serves to prevent mark
