Evaluation of linear wind flow models with complex terrain field data

摘要

In recent years data on wind flow over isolated hills have been obtained in a number of experimental studies and these have been compared with the results form various numerical models. Flow over complex terrain, which envompasses a range of topography from rolling countryside to groups of isolated terrain features, is less well understood and few experimental data are available. The work described in this poster presentation mainly makes use of meteorological data from the MADONA~1 experiment, conducted on the DERA Porton Range, Salisbury, UK in September 1992, to assess the performance of linear wind flow models over the moderately complex terrain encountered on this site. These terrain and meteorological conditions fall well within the limiting criteria suggested for application of the models.
