Generally, winds are least gusty over large water surfaces and most gusty over rough land and near high buildings. According to U.S. weather observing practice, gusts are reported when the peak wind speed reaches at least 16 knots and the [[variation]] in wind speed between the peaks and lulls is at least 9 knots. The duration of a gust is usually less than 20 s.</div><br/> </div>
