Mountain wave
NettetUnderstanding Mountain Wave: Mountain wave occurs when air is being blown over a mountain range or even the ridge of a sharp bluff area. The results may be (severe) increases/decreases in airspeed and (severe) uncommanded changes in altitude.

Its methodology relies on the spatial and temporal distribution of winds, stability, and clouds to forecast and verify mountain wave turbulence. Analyzed forecast products include NWP charts, cross sections and soundings, satellite imagery, RAOBs, ...
NettetThe mountain waves are detected using visible clouds features from the satellite observations. We utilized both polar-orbiting and geostationary satellite observations to locate the mountain waves downwind of mountain peaks. NettetIn the intermountain west the wave length can vary from about 2 nautical miles to over 25 nautical miles. It averages 8 miles and extends downrange about 150-300 nautical miles. Satellite photos have shown …
Nettet31. mar. 1993 · Mountain lee waves are ducted waves that extend long distances downwind from the mountain. We have see in Chapter 3 that a mountain generates a spectrum of vertically propagating gravity waves. For wave ducting to occur, downward wave reflection must occur, and this will happen at some height for some wave only if …
Nettet24. jun. 2024 · Mountain waves (orographic gravity waves) are stationary waves in the lee of a mountain which can develop in a stably stratified atmosphere (e.g. Fritts and Alexander , 2003) when a sizeable component of the large-scale flow is perpendicular to the mountain range. fallout 4 upside downNettetMountain Waves. Over the plains air moves more or less horizontally. When air blows against a mountain or a hill, it climbs over its slope and descends on the other side. Thereafter, for some distance it does not flow horizontally even when the ground below has once again become plain. It acquires a wavy motion in a deep layer. fallout 4 upright bathtubNettetBeskrivelse 31. mai 2024 oppstod tydelige lenticularisskyer over Tromsdalstinden og omkringliggende fjell i Tromsø.
