Why does it not add up to 365 days? Defination of 'wind' is “Sustained wind speeds are reported globally at a 10 meters (33 ft) height and are averaged over a 10 minute time frame. A short burst of high speed wind is termed a wind gust, one technical definition of a wind gust is: the maxima that exceed the lowest wind speed measured during a ten-minute time interval by 10 knots (5 m/s) for periods of seconds. A squall is an increase of the wind speed above a certain threshold, which lasts for a minute or more.”
