Data from airborne air-sensing probes reveal wave structures in the planetary boundary layer of the atmosphere in the wind corridor of south-central Wyoming. The airflow, which is nearly laminar throughout much of the region, responds in a series of resonant lee waves when it encounters topographic obstacles. Gravity waves and turbulent mixing are associated with a downward transport of vertical momentum and occur in the region of accelerated windflow in the central Wyoming wind corridor. Kelvin-Helmholtz waves are prevalent in the area of hydraulic jump at Windy Gap. Understanding of such waves and their controls is essential to siting of wind-energy systems in high-wind regions like the Wyoming wind corridor and in interpreting the mechanisms for development and migration of eolian landforms.
