World Record for Fastest Wind Speed

Have you ever felt a strong gust of wind and wondered whats the fastest wind ever recorded on the surface of the Earth? World Record for Fastest Wind Speed The fastest wind speed ever recorded comes from a hurricane gust. On  April 10, 1996, Tropical Cyclone Olivia (a hurricane) passed by Barrow Island, Australia. It was the equivalent of a  Category 4 hurricane at the time,  254 mph (408 km/h).   Americas Highest Wind   Before Tropical Cyclone Olivia came along, the highest wind speed measured anywhere in the world  was  231 mph (372 km/h). It was recorded at the summit of Mount Washington, New Hampshire on April 12, 1934. After Olivia broke this record (which was held for nearly 62 years), the Mount Washington wind became the second-fastest wind worldwide. Today, it remains the fastest wind ever recorded in the United States and in the Northern Hemisphere.  The U.S. commemorates this record every April 12 on Big Wind day. With a slogan like Home of the Worlds Worst Weather, Mount Washington is a location known for having harsh conditions. Standing at  6,288 feet, it is the highest peak in the Northeastern United States. But its high elevation isnt the only reason it regularly experiences heavy fogs, whiteout conditions, and gales. Its position at the crossroads of storm tracks from the Atlantic to the south, from the Gulf, and from the Pacific Northwest makes it a bullseye for storminess. The mountain and its parent range (the Presidential Range) are also oriented north-south, which increases the likelihood of high winds.  Ã‚  Air is commonly forced over the mountains, making it a prime location for high wind speeds.  Hurricane-force wind gusts are observed at the mountains summit nearly a third of the year. It is a perfect spot for weather monitoring, which is why it is home to a  mountaintop weather station called the Mount Washington Observatory. How Fast Is Fast? When it comes to wind, 200 miles per hour is fast. To give you an idea of just how fast it is, lets compare it to wind speeds you may have felt during certain weather conditions: Blizzard winds blow at 35 mph or moreWinds in a severe thunderstorm can gust in the 50 to 65 mph rangeA weak category 5 hurricanes strongest sustained winds blow at 157 mph When you compare the 254 mph wind speed record to these, its easy to tell that that is some serious wind! What About Tornadic Winds?   Tornadoes are some of the weathers most violent windstorms. Winds inside of an EF-5 tornado can exceed 300 mph. Why then, arent they responsible for the fastest wind? Tornadoes usually arent included in the rankings for the fastest surface winds because there is no reliable way to measure their wind speeds directly. Tornadoes destroy weather instruments. Doppler radar can be used to estimate a tornados winds but because it only gives an approximation, these measurements cannot be seen as definitive. If tornadoes were included, the worlds fastest wind would be approximately 302 mph (484 km/h). It was observed by a Doppler on Wheels during a tornado occurring between Oklahoma City and Moore, Oklahoma on May 3, 1999.
