Abstract

A two‐dimensional theory of Jackson and Hunt for turbulent flow over a shallow ridge is extended to three‐dimensional topography. The results are compared both with theoretical results for a ridge and with surface wind observations from a nearly circular isolated hill. Agreement between theory and observations is encouraging.

## Abstract Perturbation theory is used to compute the vertical displacement of a uniform airstream passing over a solitary hill: first for a circular hill, then for a hill of oval section lying across the wind, obliquely to it and along it. The diagrams show contours of the vertical displacement a

A computationally efficient model -the MS3DJH -was used to predict the near-surface wind-speed variations over a given idealised twin hill. Results given compare the model predictions with those of trained meteorologists. Further application of the model to assessment of e.g. power-producing turbine
