One man needed to be rescued by helicopter from the damaged White Rock Pier and a woman was killed in Duncan after being struck by a tree. [19] 2021: October 2021 Northeast Pacific bomb cyclone. Powerful storm system that underwent rapid bombogenesis with air pressure bottoming out at 942 hPa. Heavy rain and snow along with strong winds were ...
The station model uses a wind barb to show both wind direction and speed. The wind barb shows the speed using "flags" on the end. Each half of a flag depicts 5 kn (9.3 km/h; 5.8 mph) Each full flag depicts 10 kn (19 km/h; 12 mph) Each pennant (filled triangle) depicts 50 kn (93 km/h; 58 mph) [4]
The Santa Anas are katabatic winds (Greek for "flowing downhill") arising in higher altitudes and blowing down towards sea level. [7] The National Weather Service defines Santa Ana winds as "a weather condition [in southern California] in which strong, hot, dust-bearing winds descend to the Pacific Coast around Los Angeles from inland desert regions".
A small craft advisory is a type of wind warning issued by the National Weather Service in the United States. In Canada a similar warning is issued by Environment Canada. It is issued when winds have reached, or are expected to reach within 12 hours, a speed marginally less than gale force. A Small Craft Advisory may also be issued when sea or ...
An anemometer is commonly used to measure wind speed. Global distribution of wind speed at 10m above ground averaged over the years 1981–2010 from the CHELSA-BIOCLIM+ data set [1] In meteorology, wind speed, or wind flow speed, is a fundamental atmospheric quantity caused by air moving from high to low pressure, usually due to changes in ...

At times, multiple vortices swirled within the tornado, which lasted for about 45 minutes and traveled about 44 miles. For less than a second, the researchers calculated wind speeds of more than ...
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 (19 km/h; 12 mph) for periods of seconds. A squall is an increase of the wind speed above a certain threshold, which lasts for a minute or more.
