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
Great Storm of 1854 was commanded to set up a storm warning system; this later developed into an international meteorological service. Though it is impossible to precisely calculate the strength or speed of the wind, estimates have placed it around force 11 on the Beaufort Scale. Great Storm of 1854 The Great Storm of 1854 (also known as the Balaklava Storm) occurred in and around the Black Sea on 14 November 1854. It caused severe damage and caused major disruption to armed forces (and especially naval forces) in the region engaged in the Crimean War. At the time of the storm, the British and
