A MODEL STUDY OF THE ONE-DIMENSIONAL NONSTATIONARY NOCTURNAL BOUNDARY LAYER OVER A SLOPED TERRAIN
Abstract:In this study, a numerical model of one-dimensional nonsta-tionary boundary layer over a sloped terrain is established. Emphasis is put on the characteristics of Ekman spirals over the sloped terrain.Conditions in which Ekman spirals move counterclockwise (ccw) and the relationship between frictional force and Ekman spiral pattern are given as well.
