Mount Washington once held the world record (still the Northern Hemisphere and Western Hemisphere record) for directly measured surface wind speed, at 231 mph (372 km/h), recorded on the afternoon of April 12, 1934. Although this record was surpassed in Cyclone Olivia in 1996, this wasn't reported as official until 2010.[10] It can still be argued that Mount Washington holds the record for the highest surface wind speed recorded 'by man'; the new Australian record was measured by an automated station while no human was present, while the Mount Washington wind gust was actually measured by a human being. Phenomena measured via satellite or radar, such as tornadoes, hurricanes, and air currents in the upper atmosphere, are not directly measured at the Earth's surface and do not compete with either of these records.
