Eddy Dissipation Rate in Aviation Applications for Estimation of Turbulence Intensity

A review of papers on the use of the EDR (eddy dissipation rate) parameter in meteorological service for air navigation is presented. EDR is associated with the rate of turbulent kinetic energy dissipation; it is the cube root of its value. The EDR measure independent of aircraft type, has been designated by ICAO as the measure for determining turbulence intensity. The physical basis of the EDR application, methods for determining EDR in flight and in the atmosphere boundary layer using remote sensing are discussed. Some approaches to forecasting turbulence in EDR units with numerical weather forecast models are considered.
