Bureau of Meteorology - your eye on the wind environment
The wind is a continuous succession of gusts and lulls (quiet intervals) associated with equally rapid changes of direction over a range which may exceed 30°. Usually only the mean wind is forecast, unless the gusts are expected to be a significant feature. For instance, Fresh, gusty southwest winds indicates that the mean wind speed will be between 17 and 21 knots and the mean wind direction will be from the southwest, but that there will also be gusts to speeds significantly higher than the mean.
Gust: a gust is any sudden increase of wind of short duration, usually a few seconds.
Squall: a squall comprises a rather sudden increase of the mean wind speed which lasts for several minutes at least before the mean wind returns to near its previous value. A squall may include many gusts.
Surface Wind: wind speed and direction measured at 10 metres above the earth's surface. The surface wind drives wave generation locally, and is responsible for large swells generated by strong winds associated with intense storms.
