Turbulence. Turbulence is defined as "Irregular motion of an aircraft in flight, especially when characterized by rapid up-and-down motion, caused by a rapid variation of atmospheric wind velocities". This section will cover clear-air turbulence. For information on turbulence caused by convection, visit our section on thunderstorms.
