The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
[citation needed] Katabatic wind in Antarctica. A katabatic wind (named from Ancient Greek κατάβασις 'descent') is a downslope wind caused by the flow of an elevated, high-density air mass into a lower-density air mass below under the force of gravity. The spelling catabatic [1] is also used. Since air density is strongly dependent on ...

Santa Ana winds are katabatic, gravity-driven winds, draining air off the high deserts, while the Diablo-type wind originates mainly from strongly sinking air from aloft, pushed toward the coast by higher pressure aloft. Thus, Santa Anas are strongest in canyons, whereas a Diablo wind is first noted and blows strongest atop the various mountain ...
