WebTurbulence is an irregular motion of the air resulting from eddies and vertical currents. It may be as insignificant as a few annoying bumps or severe enough to momentarily throw an airplane out of control or to … WebTurbulence caused by vertical currents of air in an unstable atmosphere. Common causes and sources of CAT are: Jet Stream. A Jet Stream is a narrow, fast moving current of air, normally close to the Tropopause and generated as a result of the temperature gradient between air masses.

WebAug 7, 2024 · Increased vertical wind shear has important implications, not only for clear-air turbulence and its impacts on aviation, but also for the turbulent mixing of atmospheric … Webvertical mixing, in the atmosphere or oceans, an upward and downward movement of air or water that occurs as a result of the temperature gradients (temperature differences between layers of the fluid ). In the atmosphere vertical mixing is sometimes discernible as a form of atmospheric turbulence. WebMay 31, 2016 · Turbulence can also be expected at high altitudes in the vicinity of any jet streams (tubes of strong wind flowing for many hundreds or thousands of miles, usually from west to east). Turbulence above 15,000 feet AGL that is not associated with cumuliform clouds is known as clear air turbulence (CAT). If there is a change in wind … dr christy huff
