[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 ...
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".
The Santa Ana winds of Southern California can be visualized in several ways. You can see their effects as palm trees sway in the morning light or when clean-up crews arrive to deal with branches ...
Diurnal wind system variation in the Appalachian mountain range. Mountain and valley breezes form through a process similar to sea and land breezes. During the day, the sun heats up mountain air rapidly while the valley remains relatively cooler. Convection causes it to rise, causing a valley breeze. At night, the process is reversed.
The winds are also blowing the embers of the Eaton Fire, which is impacting the cities of Pasadena and Altadena in northeast L.A. County. What are Santa Ana winds?
A serious wildfire situation has unfolded for coastal areas of Southern California as a powerful Santa Ana event that can even reach into the metro areas of Los Angeles and San Diego continues ...
Buran (a wind which blows across eastern Asia. It is also known as Purga when over the tundra); Karakaze (strong cold mountain wind from Gunma Prefecture in Japan); East Asian Monsoon, known in China and Taiwan as meiyu (梅雨), in Korea as jangma (), and in Japan as tsuyu (梅雨) when advancing northwards in the spring and shurin (秋霖) when retreating southwards in autumn.
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 ...
