Nettet1. mar. 2012 · Abstract Heterogeneous ice nucleation is a source of uncertainty in models that represent ice clouds. The primary goal of the Ice in Clouds Experiment–Layer … Both lee waves and the rotor may be indicated by specific wave cloud formations if there is sufficient moisture in the atmosphere, and sufficient vertical displacement to cool the air to the dew point. Waves may also form in dry air without cloud markers. Wave clouds do not move downwind as clouds usually do, but … Se mer In meteorology, lee waves are atmospheric stationary waves. The most common form is mountain waves, which are atmospheric internal gravity waves. These were discovered in 1933 by two German glider pilots, … Se mer Lee waves provide a possibility for gliders to gain altitude or fly long distances when soaring. World record wave flight performances for speed, distance or altitude have been … Se mer • Gravity wave • Nor'west arch Se mer • Mountain Wave Project official website • Chronological collection of meteorological data, satellite pics and cloud images of mountain waves in Bariloche, Argentina (in Spanish) Se mer Lee waves are a form of internal gravity waves produced when a stable, stratified flow is forced over an obstacle. This disturbance elevates air parcels above their level of Se mer There are a variety of distinctive types of waves which form under different atmospheric conditions. • Wind shear can also create waves.

Mountain waves sometimes reveal … Nettet1. jan. 2024 · Atmospheric internal gravity wave cloud, commonly known as lee-wave cloud, used to form over the north-eastern slope of Ascraeus Mons and the eastern … NettetLee waves can have significant impacts on aviation, particularly in mountainous regions. Turbulence caused by lee waves can be unpredictable and sudden, making it challenging for pilots to anticipate and avoid. Additionally, rotor clouds can create dangerous flying conditions, and wave clouds can obscure visibility. down stream nyt crossword
