A Model for Objective Simulation of Boundary-Layer Winds in an Area of Complex Terrain

Abstract

An objective analysis model is formulated to simulate the boundary-layer wind field in an area of complex terrain on the island of Oahu, Hawaii. The model is designed to reproduce the effects of the terrain on the undisturbed trade wind flow in the area of interest. Mathematical algorithms representing surface roughness effects, cross-valley flow separation, ridge amplification, wind direction shear and, where applicable, the mass consistency principle are incorporated in the model.
