The National Weather Service's arrow showing the EF scale. This includes a description word for each level of the scale. The Enhanced Fujita scale (abbreviated as EF-Scale) is a scale that rates tornado intensity based on the severity of the damage they cause.
Completed Tornado Diagram. Tornado diagrams, also called tornado plots, tornado charts or butterfly charts, are a special type of Bar chart, where the data categories are listed vertically instead of the standard horizontal presentation, and the categories are ordered so that the largest bar appears at the top of the chart, the second largest appears second from the top, and so on.
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]
Two tornadoes that look almost the same can produce drastically different effects. Also, two tornadoes that look very different can produce similar damage, because tornadoes form by several different mechanisms and also follow a lifecycle that causes the same tornado to change in appearance over time. People in the path of a tornado should ...
Date: 1994 and 1995: Location: Tornado Alley: Also known as: Verification of the Origins of Rotation in Tornadoes Experiment 1: Outcome: Documented an entire tornado, which, in conjunction with deployment of the NEXRAD system, helped the National Weather Service to provide severe weather warnings with a thirteen-minute lead time, and reduce false alarms by ten percent.
During the afternoon hours of May 27, 1997, a large and slow-moving F5 tornado caused extreme damage across portions of the Jarrell, Texas area. The tornado killed 27 residents of the town, mainly in a single subdivision, and inflicted approximately $40 million (1997 USD) in damages in its 13-minute, 5.1 miles (8.2 km) track.
These tornadoes may form at different times or exist simultaneously but are separate from one another. A phenomenon similar to multiple vortices is the satellite tornado. Unlike the multiple-vortex tornado, where smaller vortices form inside the main tornado, a satellite tornado develops outside the main tornado's circulation.
