On the Prediction and Evaluation of the Ground Level Wind Environment.

摘要

Tentative acceptance criteria for ground level wind speeds are presented together with a description of an experimental approach to the prediction of the ground level wind environment. The method of prediction relies on the use of models to determine the ratios of the ground level mean and gust speeds to a reference speed at a height well clear of the influence of terrain roughness. The measured wind speed ratios are then used in conjunction with the known statistics of the reference speed to predict the ground level climate. In the Sydney area the statistics of the reference speed were derived from balloon data.
