tornado a highly localized, violent windstorm occurring over land, usually in the U.S. Midwest, characterized by a vertical, funnel-shaped cloud. twister whirlwind. typhoon a cyclone or hurricane in the western Pacific Ocean. whirlwind any wind that has a spinning motion and is conflned to a...
When you compare the 254 mph wind speed record to these, it's easy to tell that that is some serious wind! What About Tornadic Winds? Tornadoesare some of the weather's most violent windstorms. Winds inside of an EF-5 tornado can exceed 300 mph. Why then, aren't they responsible for...
Water content can be used to visually represent wind speed in typhoon and tornado weather [55]. Sensors that can measure the content of ice, liquid, rain, and snow water include cloud radars, disdrometers, satellite-based sensors like AMSR, CALIPSO, CloudSat’s Cloud Profiling Radar (CPR), ...
The wind speed depends on the geographic location of the building. This is one of the main reasons which today justify in the standards, the regional division (wind zone) and the consideration of the altitude, as well as the variation of the dynamic pressures according to the height above ...
As the wind blows across the tube, a pressure differential is created that can be mathematically related to wind speed. Doppler radar can be used to measure wind speed by shooting pulses of microwaves that are reflected off rain, dust, and other particles in the air, much like the radar ...
Tests should be carried out on a properly scaled model of the full scale shape of the structure. The actual wind should be modeled to account for the variation of the meanwind speedwith height above ground or seawater, and the turbulence level in the wind. ...
Wind is moving air that is caused by the difference in air pressure due to temperature differences. Learn facts about the wind and explore what causes wind and how it can be harnessed. What is Wind? In a hurricane, it can reach speeds of more than 130 miles per hour. In a tornado, ...
This type of data is typically composed of three values:Wind Speed,Wind Direction, andWind Gust. In the case of an hourly weather record, this measure reports the average speed over the past two-minute time window immediately before the report. In the case of a daily weather record, win...
(RIJ). Microscale processes along squall lines can enhance these winds and produce damaging, straight-line winds, and perhaps even a tornado at the top of any notches. On the right is how radar detects it. You'll usually notice a pocket of fast velocities in any bowing or concavity ...
To create a supercell, take a storm where wind speed increases with height, while wind direction veers; a situation in which updraughts and downdraughts within the thunderstorm can support each other's existence rather than cancel each other out. It is as winds blow into this turbulent region...
