Abstract：Based on the wind profile radar data of Manzhouli west suburban airport in August 2020,this paper calculates the turbulent dissipation rate ε.The turbulent dissipation rate ε,refractive index structure constant C2n,horizontal wind speed and vertical wind speed under typical weather conditions in Manzhouli are analyzed.The variation range of atmospheric turbulence dissipation rate ε is obtained.The turbulent dissipation rate ε has obvious spatial and temporal distribution characteristics.The turbulence dissipation rate ε calculated by wind profile is consistent with the data recorded by airborne QAR,which could provide a reference for the application of wind profile radar turbulence detection.
