Wind gust World Meteorological Organization. Any significant variation at this mean wind during the ten minutes preceding the observation are noted as gusts in messages such as METAR. It is generally reported in METAR when the peak wind speed reaches at least 16 knots and the variation in wind speed between the peaks and average wind is at least 9 to 10 knots. In marine meteorology, the top speed of a burst is expressed in meters per second (m/s) or in knots, while the Beaufort scale is used for reporting the mean speed. When the maximum speed exceeds the average speed by
War Wind have to be promoted at a specific facility. Additionally, units could be individually upgraded in a variety of areas such as speed, strength, resilience, stealth, and vision. The purpose for these micro upgrades was to encourage more strategic and smaller conflicts instead making players simply building up units and "steam rolling" the opposition.
