Abstract
In this present study, wind tunnel experiments were conducted to measure the flow and turbulence characteristics for wind over an upwind slope of 15° escarpment. The mean wind speed and turbulence statistics, such as turbulence intensity, Reynolds stress, and wind power spectrum are investigated. Results indicate that wind speed-up phenomenon (increase of speed) occurred significantly around the tip of the upwind slope. The turbulence intensity decreases gradually as the wind flows from the toe of upwind slope to the tip of upwind slope. The wind power spectra for several sites along the upwind slope and top surface of escarpment at lower height display a -5/3 slope in the inertia-subrange, as predicted by the Kolmogorov’s hypothesis. And the dominant spectrum peak was not found as wind over the upwind slope and top surface of escarpment.
