Description
Summary:The thesis examines the applicability of a two-dimensional flow acceleration model to describe a terrain-induced flow perturbation as measured at Yaquina Head on the central Oregon coast. The geometry of Yaquina Head together with the upstream wind values were used in estimating hilltop winds. These estimates compare well with the observed wind values. A second method to estimate the hilltop winds was attempted by developing a mean ratio of Yaquina Head winds to the upstream Yaquina South Jetty winds. This ratio was taken from one winter's data and used to estimate the next winter hilltop winds. The same upstream wind values were used with this method as were used with the geometric model. Statistical evaluation in the form of regression analysis was performed to determine the ability of the geometric and statistical models to estimate the hilltop wind on Yaquina Head. It was found that both models did reasonably well but that neither model was appreciably better than the other. === Graduation date: 1979
