The purpose of this paper is to describe the latest version of a wake-vortex eddy-dissipation model devised by T. Sarpkaya (New Model for Vortex Decay in the Atmosphere, Journal of Aircraft, Vol. 37, No. 1, 2000, pp. 53-61.) and to compare its predictions with lidar observations obtained at Memphis and Dallas/Fort Worth airports. The model simulates the evolution of aircraft-generated trailing vortices in an atmospheric environment defined by vertical profiles of potential temperature, eddy-dissipation rate, and crosswind. Visual and quantitative comparisons of the time histories of altitude, circulation, and lateral position of predicted and measured vortices are presented.
