A horizontal temperature gradient may occur, and hence air density variations, where air velocity changes. An example: the speed of the jet stream is not constant along its length; additionally air temperature and hence density will vary between the air within the jet stream and the air outside. Cirrus clouds often associated with clear-air ...
Two hours into the flight, at an altitude of 31,000 feet (9,400 m), the plane received reports of severe clear-air turbulence in the area and the seat belt sign was turned on. Moments later, the aircraft suddenly dropped around 100 feet (30 m), seriously injuring 15 passengers and 3 crew members. [2]
Pilots of a Hawaiian Airlines flight in 2022 that resulted in dozens of turbulence injuries should have gone around a “plume” of bad weather, the NTSB report says.
A spate of turbulence reports has triggered a debate over whether climate change may be causing more turbulence. A report from the University of Reading last year suggested turbulence could worsen ...
It appears the Boeing 777-300 encountered clear air turbulence over the Bay of Bengal, south of the southern tip of Myanmar, just before 9am British time. A turn towards Bangkok and a rapid ...
A pilot report or PIREP is a report of actual flight or ground conditions encountered by an aircraft. Reports commonly include information about atmospheric conditions (like temperature , icing , turbulence ) or airport conditions (like runway condition codes or ground equipment failures).
Pilots are sometimes warned of reports of turbulence by the Federal Aviation Administration, airline meteorology teams or even other pilots flying ahead of them in advance. However, turbulence can ...
Data from turbulence prediction website Turbli, which has analysed around 150,000 routes, shows the most turbulent journeys of 2023. Routes are ranked according to “eddy dissipation rate ...
