Abstract
Three types o atationary waves are described. The maintenance of the most powerful one-the lee wave-is thought to be the system of vortex pairs, which are periodically released by the mountain ridge. This syatem, called 'active turbulent layer' (ATL), induces in the airflow wave-like deformations and special turbulence, wind and pressure distribution throughout the lee area. The dependence of the dimension and intensity of the ATL on both topographical and meteorological conditions is discissed. Some effects on transient aircraft are shown.
