First, there are damage indicators — objects that a tornado can damage. These range from 1 (small barns) to 28 (softwood trees). Each damage indicator can also experience varying degrees of damage (DODs). Each DOD corresponds to estimated wind speeds. For example, a motel has 10 ...

How is Tornado Strength Rated?Like hurricanes, tornadoes have different strength classifications based on wind speeds. The only problem is that it’s nearly impossible to measure the actual wind speed inside a tornado. Most weather stations don’t make it through one of these storms unscathed!
A strong wind blows down many trees. What natural disaster might it be? A. Tornado B. Earthquake C. Flood D. Drought 相关知识点: 试题来源: 解析 A。选项 A“Tornado”是龙卷风;选项 B“Earthquake”是地震;选项 C“Flood”是洪水;选项 D“Drought”是干旱。强风刮倒很多树可能是龙卷风。
in desert regions. A waterspout is a tornado formed over a body of water. A landspout is similar to a waterspout, but it is much weaker than a supercell. Firewhirls are formed from the smoke of forest fires or volcanoes, and they can have wind speeds of up to 100 miles per hour....
Tornadoes are extremely violent storms. They occur when warm, moist air converges with cold air. This typically occurs in late summer and early spring in North America. Tornado's are not as large as hurricanes, but can have higher wind speeds. ...
What are some of the effects of a tornado? Tornadoes: A tornado is a weather phenomenon which takes the form of a spinning, funnel-shaped cloud that touches the ground. The Midwest is the part of the United States that is most commonly affected by tornadoes. ...
“Tornado” and “twister” are used interchangeably because they’re basically the same thing: a rotating column of air that spins at high speeds. The width of a tornado can range from a couple of feet to several hundred feet across, and they can last between a few seconds to a half ...
Tornadoes form when certain ingredients are in place including high instability and vertical wind shear meaning winds are changing with height. This slide goes into some of the science of tornado formation and covers some safety tips as well.#SpringSafety#houwx#bcswxpic.twitter.com/MGRKquOIKm ...
Drones provide valuable footage in areas that are not accessible by foot or vehicle. We also now have an Enhanced Fujita scale rolled out in 2007 with more damage indicators, allowing storm survey crews to give better estimates of tornado wind speeds. Dr. Fujita's landmark survey of the ...
