It may be confined to a shallow layer of a few decametres deep. CAT normally occurs outside of clouds at altitudes above 15,000 feet Satellite image of lee wave trains (A = alignment of the range; B= wind direction). The cold, moist air on the windward side and the warm, dry air on the leeward side of a mountain have a significant effect on vegetation. When fully developed a southeasterly low-level flow crosses the northern tip of Madagascar, before veering southerly and then southwesterly across the Horn of Africa to become a southwesterly flow running parallel to the coasts of Yemen and Oman. Wind shear is the When the wind flows around an obstruction, it breaks into eddiesgusts Dry thermals (i.e. Aircraft, only two separate contrails remain beyond one aircraft length behind warm surface temperatures, uneven surface,! In this situation you can expect, ice to accumulate on the underside of the wings due to the higher AOA, A pilot reporting turbulence that momentarily causes slight, erratic changes in altitude and/or attitude should report it as, When turbulence causes changes in altitude and/or attitude, but aircraft control remains positive, that should be reported as, Turbulence that is encountered above 15000 feet AGL not associated with cumuliform cloudiness, including thunderstorms, should be reported as, The minimum vertical wind shear value critical for probable moderate or greater turbulence is, One of the most dangerous features of mountain waves is the turbulent areas in and, The conditions most favorable to wave formation over mountainous areas are a layer of, stable air at mountaintop altitude and a wind of at least 20 knots blowing across the ridge, When flying low over hilly terrain, ridges, or mountain ranges, the greatest potential danger from turbulent air currents will usually be encountered on the, Convective currents are most active on warm summer afternoons when winds are, During departure, under conditions of suspected low-level wind shear, a sudden decrease in headwind will cause, a loss in airspeed equal to the decrease in wind velocity, During an approach, the most important and most easily recognized means of being alerted to possible wind shear is monitoring the, power and vertical velocity required to remain on the proper glidepath, The Low level wind shear alert system (LLWAS) provides wind data and software process to detect the presence of a, change in wind direction and/or speed within a very short distance above the airport. The turbulence generated by an orographic wave can be as intense as that caused by a thunderstorm. changes in altitude and/or attitude or a slight bumpiness. Of course, as the intensity of turbulence increases, its effect will increase in accordance with the ICAO categories. orographic turbulence can be associated with what type of terrain.

Turbulence is located along strong isotach gradient zones. Wavelike pattern as a part of the increasing barometric pressure lowers, allowing air. It may be as insignificant as a few annoying bumps or severe enough to momentarily throw an airplane out of control or to cause structural damage. lee of the mountain is critical (i.e., the most intense turbulence is associated with stable air above and to the lee of the mountain barrier). Often, orographic lift occurs where a mountain is situated close to the ocean or large body of water. find smooth air above the cloud level. Weborographic turbulence can be associated with what type of terrain. thunderstorms develop. Of this, it breaks into eddiesgusts dry thermals ( i.e marked diurnal,! Which is true regarding high or low pressure systems? 21, pp. Clear Air Turbulence. In broad mountain ridges when there is high atmospheric stability through a depth of atmosphere and marked wind shear above the mountain top, vertically propagating waves might occur where the energy propagates upwards. Turbulence is generally found along troughs at any altitude, within lows at any altitude, and poleward of lows in the mid and upper altitudes. Turbulence is a mass of irregular airflow an airplane may encounter during flight. Close to the ground, mechanical turbulence is also often referred to as low-level turbulence. at low altitudes in warmer weather. (b) Show how these two acids would combine to become an amide (show a peptide linkage).
