Average Wind Speed (or Velocity) is the mean wind speed over a specified period of time. (e.g., The gust speed and direction are defined by the maximum three second average wind speed occurring in any period. The overall wind intensity is defined by the average speed and direction over the ten minutes period leading up to the reporting time. A gale is defined as a surface wind of mean speed of 34-40 knots, averaged over a period of ten minutes.)
