Abstract

The theory by Rice for extreme value statistics is used to study the influence of filters in a wind measuring system on the measured gusts. An extension is made to discretely sampled data. Model results are compared with strong wind data from the Cabauw tower. On the basis of this theory a definition is proposed for the duration of gusts. Also a data reduction scheme for standard synoptic and climatological stations is proposed. Such a standardization would enhance the applicability of wind gust climatology.
