Reliably predicting tornado intensity and longevity remains a problem, as do details affecting characteristics of a tornado during its life cycle and tornadolysis. Other rich areas of research are tornadoes associated with mesovortices within linear thunderstorm structures and within tropical cyclones. [138]
Some of the most notorious twisters in U.S. history were wedge tornadoes, including the EF5 that leveled Joplin, Missouri, on May 22, 2011, and the El Reno tornado, which was a jaw-dropping 2.6 ...
Tornado intensity is the measure of wind speeds and potential risk produced by a tornado. Intensity can be measured by in situ or remote sensing measurements, ...
Intensity cannot be determined due to a lack of information. This rating applies to tornadoes that traverse areas with no damage indicators, cause damage in an area that cannot be accessed by a survey, or cause damage that cannot be differentiated from that of another tornado. [4] N/A EF0: 65–85: 105–137 52.82% Minor damage.
The most active day for tornado reports was April 26, 2024, when a series of storms across the U.S. produced more than 100 tornadoes. Deadly tornadoes mark the end of 2024’s extreme weather Skip ...
The deadliest tornado in modern U.S. history struck Joplin, Missouri, on May 22, 2011. It was the deadliest tornado since SPC records began in 1950. Nearly 1,000 were injured. The EF5 tornado had ...
Tornadoes are most common in spring and least common in winter. [14] The seasonal transition during autumn and spring promotes the development of extratropical cyclones and frontal systems that support strong convective storms. Tornadoes are common in landfalling tropical cyclones, where they are focused in the right poleward section of the ...
The 1977 Birmingham–Smithfield F5 tornado's damage was surveyed by Ted Fujita and he "toyed with the idea of rating the Smithfield tornado an F6". [13] In 2001, tornado expert Thomas P. Grazulis stated in his book F5–F6 Tornadoes; "In my opinion, if there ever was an F6 tornado caught on video, it was the Pampa, Texas tornado of 1995". [14]
