WebMar 18, 2024 · In 1994, a USAir DC-9 encountered a microburst, which is turbulent. The downward-rushing air pushed the airplane into the ground. It was not the turbulence … In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet. The atmospheric region most susceptible to CAT is the high troposphere at altitudes of around 7,000–12,000 … See more In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet. In aviation, CAT is … See more Clear-air turbulence is usually impossible to detect with the naked eye and very difficult to detect with a conventional radar, with the result that it is difficult for aircraft pilots to detect and avoid it. However, it can be remotely detected with instruments that can measure … See more • Continuous gusts • Dryden Wind Turbulence Model • Ellrod index • N-slit interferometer • von Kármán Wind Turbulence Model See more At typical heights where it occurs, the intensity and location cannot be determined precisely. However, because this turbulence … See more In the context of air flight, CAT is sometimes colloquially referred to as "air pockets".

Frontal turbulence is caused by lifting of warm air, a frontal surface leading to instability, or the abrupt wind shift between the warm and cold air masses. The most severe cases of frontal turbulence are generally associated with fast-moving cold fronts. Boldmethod. he kita
