As well as making flights bumpier and less comfortable, this could also increase the risk of injury to passengers and crew"-especially in winter when Northern Hemisphere clear-air turbulence
is thought to be most intense.
A: Clear-air turbulence
is often referred to as `rough air' or `air pockets', and is a safety hazard for aircraft, as it cannot be seen, but definitely can be felt.
There he managed projects involving refractive-index turbulence and clear-air turbulence
in the free atmosphere.
At NASA's Langley Research Center, Zuckerwar is investigating how to use infrasound data to warn airplane pilots of clear-air turbulence
Since lee-side troughing is strongly associated with clear-air turbulence
(CAT), it's always a good idea to sift carefully through the turbulence forecasts and PIREPs in this kind of pattern.
Supercell thunderstorms, on the other hand, often produce dangerous clear-air turbulence
downwind that's essentially invisible.
