Wind Flow near the Surface over Nonuniform Terrain.

Abstract

The OSU/Riso Project is an ongoing study of air flow near the ground over complex terrain. The study combines field observations, data analysis, and theoretical modelling in order to assess and understand the effects of terrain features on the mean flow and turbulence structure in the lower portion of the planetary boundary layer. The method of approach is to choose sites with horizontal scales of less than several hundred meters which have a distinctive inhomogeneity but whose boundary conditions are otherwise relatively simple so that there is some hope of constructing theoretical models, to instrument the site as fully as possible to measure the relevant details of the flow, to conduct observations over a long enough period of time to obtain a clear record of the characteristics of the flow, and then to analyze the accumulated data, reconcile the observations with our theoretical constructs, and finally to improve the theory.
