Occasionally, the old (occluded) mesocyclone and the new mesocyclone produce a tornado at the same time. [citation needed] Although this is a widely accepted theory for how most tornadoes form, live, and die, it does not explain the formation of smaller tornadoes, such as landspouts, long-lived tornadoes, or tornadoes with multiple vortices.
A tornado, marked by debris swirl on the ground and connected to a thundercloud, with no condensation funnel. It is commonly and mistakenly thought that if the condensation funnel of a tornado does not reach the ground, then the tornado cannot cause substantial damage. Furthermore, a tornado is sometimes believed to be on the ground only when ...
Sand will fuse into glass if it is close enough to the nuclear fireball to be drawn into it, and is thus heated to the necessary temperatures to do so; this is known as trinitite. [39] At the explosion of nuclear bombs lightning discharges sometimes occur. [40] Smoke trails are often seen in photographs of nuclear explosions.
Tornadoes can occur anywhere in the U.S., according to the National Weather Service.Tornadoes are “most common in the central plains east of the Rocky Mountains and west of the Appalachians.”
The original scale is named after Dr. Ted Fujita, who developed the system to help provide a wind estimate for the amount and type of damage that a tornado can produce. In 2007, the Enhanced ...

Hurricane Milton's tornadoes in Florida were a leading cause of death and damage from the storm. The U.S. has seen an abnormal number of intense tornadoes linked to hurricanes this year.
Most tornadoes have wind speeds of less than 180 km/h (110 mph), are approximately 75 m (250 ft) across, and travel a few kilometers before dissipating. The most extreme tornadoes can attain wind speeds of more than 480 km/h (300 mph), attain a width exceeding 3 km (2 mi) across, and stay on the ground for perhaps more than 100 km (60 mi).
