Predicting wind velocities from sand dune and draa spacings determined by Fourier analysis in Interpretation of windflow characteristics from Eolian landforms.
The spacing of sand dunes and draas (dune groups) is one parameter that can be used to estimate wind velocity and available wind power. Measurements of spacings can be made directly from LANDSAT imagery or aerial photography. Fourier analysis
). These values may then be used to estimate wind velocity at any other height above the surface or to estimate available wind power.
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
Predicting the surface wind characteristics of southern Wyoming from remote sensing and eolian geomorphology in Interpretation of windflow characteristics from Eolian landforms.
Interpretation of eolian features detectable on LANDSAT imagery provided the information for regional assessment of windflow patterns in the southern high plains. A map was compiled summarizing the interpretations. Recorded wind data were correlated
