Wind gust 10 to 15 knots, the term "gusts" is used while "strong gusts" is used for departure of 15 to 25 knots, and "violent gusts" when it exceeds 25 knots. Wind gust A gust or wind gust is a brief increase in the speed of the wind, usually less than 20 seconds. It is of a more transient character than a squall, which last minutes, and is followed by a lull or slackening in the wind speed. Generally, winds are least gusty over large water surfaces and most gusty over rough land and near high buildings. The wind is measured using
Wind power in the United Kingdom and wind regimes, are smoothed, rather than intermittent. As the distance between sites increases, the correlation between wind speeds measured at those sites, decreases. The combined output of multiple wind turbines widely distributed across the UK gives a normal distribution of power, with a standard deviation which is about 0.76 of the average power. A Scottish government spokesman has said electricity generated by renewables accounted for 27% of Scotland's electricity use. On the night of 5–6 April 2011, the wind in Scotland was high, it was raining heavily, which also created more hydroelectricity than normal. The grid became overloaded preventing
