Introduction of clear sky protrusion

Clear sky turbulence refers to the turbulence of aircraft caused by atmospheric activities at cloudless altitude. Usually, due to the earth's rotation and solar radiation, the atmosphere will form a jet zone at high altitude (generally above 7000 meters) in some places, with a width ranging from tens to hundreds of kilometers. When the plane strays into the rapids, it will cause the plane to take off and land suddenly, which will hurt people and damage flight safety. At present, the aviation meteorological department can predict the existence and range of jet according to the high-altitude sounding data, and pilots and dispatching departments can adjust their routes reasonably after obtaining this information to avoid danger. In any case, it is wise to fasten your seat belt throughout the flight.
