Scientists develop device to predict clear-sky turbulence for safer air travel

Turbulence in clear skies comprises the most unpleasant kind of vortex drifts in air travel. These occur in cloudless space with perfect visibility when an airplane travels between air flows that differ in direction, speed of movement, temperature and density. This is the kind of turbulence that Aeroflot flight SU-270 from Moscow to Bangkok experienced, resulting in 27 injuries of varying severity.
