FIELD: meteorology; atmospheric physics.
SUBSTANCE: group of inventions can be used to create aircraft equipment for the early detection of clear-air turbulence (CAT) ahead of an aircraft in order to ensure flight safety. The substance of the invention consists in sounding the atmosphere with a turbulent lidar from an aircraft along the flight course, recording two profiles of echo signals in the photon counting mode, transmitting signals to an electronic unit where echo signals are accumulated, the turbulence influence factor and turbulence characteristics in the flight direction are calculated. The result of the system operation is an advance assessment of the intensity of the expected aircraft turbulence in gradations of weak, moderate and strong within 30-60 seconds of flight time.
EFFECT: remote operational determination of the state of turbulence and an early assessment of the intensity of the turbulence of the aircraft.
