[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 ...
Speaking of wind, it's a good thing New Orleans moved up some of today's Mardi Gras celebrations. Wind gusts up to 70 mph were clocked in the area later. (07:10 PM EST) Winds Whip In Mississippi
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".
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 most intense winds from the storm are set to peak between 10 p.m. Tuesday night through 5 a.m. Wednesday, according to LA Fire Department Chief Kristin M. Crowley.

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 ...
“Wow! 265mph jet stream wind last night over parts of the east coast! Great for flight if it’s at your tail. Not so great, otherwise!,” meteorologist Lisa Green posted on X.
