EF5 Tornado
A rotating column of wind that erases everything in its path/Events & Phenomena
An EF5 tornado sits at the top of the Enhanced Fujita scale with estimated wind speeds exceeding 200 mph (90 m/s). These extraordinarily rare events account for less than 0.1% of all tornadoes but cause a disproportionate share of fatalities and destruction. The 2011 Joplin, Missouri EF5 tornado had a path nearly a mile wide and killed 158 people. Inside the funnel, wind speeds can vary wildly within meters, creating bizarre damage patterns where one house is obliterated while its neighbor survives.
Measurements
~40 km average for violent tornadoes; some exceed 100 km
~1 mile; the 2013 El Reno tornado reached 4.2 km wide
Strong tornadoes often last 20-60 minutes on the ground
~65 km/h typical forward motion; can vary widely
~100 hPa drop from ambient; measured in extreme cases
