Abstract
AbstractMeasurements, on occasions of strong wind, of horizontal wind gusts at heights of 12, 64 and 153 m in open country show the increase of gust speeds with height to be markedly less than that of mean wind speed. Lack of synchronism between gusts at the various heights makes it necessary, for wind‐pressure applications, to examine the maximum values of wind speed averaged over the three heights. At the times of occurrence of these maxima, the wind speed is approximately proportional to the height raised to the power 0·085. The corresponding index for the mean speed is 0·16.Some results on the structure of turbulence are applied to enable predictions of extreme vertical gust velocities to be made.
