A Model for the Surface Wind Field in Complex Terrain.

Abstract

A model for calculating terrain-influenced surface (6 meter) wind fields is described. The model determines locally generated slope and valley winds as well as mechanically affected changes in the general wind due to sheltering, diverting, ridge enhancement, and separated flow. A procedure is also given for the generation of an optimal computation grid on which the wind field is computed. Winds calculated on this optimal, and usually uneven grid, may then be interpolated by the model to a uniform grid specified by the user. The model is designed to compute wind fields without the need for surface observations. Analysis areas are arbitrary, ranging from as small as 1 sq km to as large as 50 sq km.
