Webmean and the standard deviation of the gust factor as a function of height and mean wind speed were developed. For both the mean and the standard deviation, two models were built. The first was based on the gust factor (GF) being Gaussian, and the second on the gust factor minus one (GF-1) being lognormal. The tool uses the mean WebMar 1, 2009 · The gust factor (GF) is defined as the ratio of the peak wind speed averaged over a short period to the mean wind speed averaged over a relatively long reference period. The GF is used to convert peak wind speeds averaged over a short period (e.g., 3 s) to mean wind speeds averaged over a relatively long reference period (e.g., 1 h) or vice versa. digical outlook 同期
