Abstract
The dispersion of aircraft emissions is investigated at cruising levels, i.e. in the free, stably stratified atmosphere near the tropopause. The study is based on large-eddy simulations in a domain of size 4.3 x 1.1{sup 2} km{sup 3} where the combined effects of typical atmospheric stratification, shear and turbulence are considered. The effect of a breaking gravity wave on the dispersion of the exhaust is analyzed. The mixing processes during the late wake flow are evaluated, i.e. in the dispersion and diffusion regimes when the organized flow by the wing tip vortices has ceased and the atmospheric motions gradually dominate the events. (R.P.) 7 refs.
