To calculate the forward speed of a tornado, you measure the distance it travels over a specific period. This is typically done by tracking the tornado's path on a map and identifying locations where it has touched down. Then, you divide the total distance traveled by the time taken to cover that distance, usually expressed in miles per hour (mph) or kilometers per hour (km/h). Accurate measurements often rely on radar data or eyewitness reports.
An EF5 tornado has an estimated wind speed of over 200 mph (miles per hour,) while an EF4 has wind speeds from 166 up to 200 mph. The scale approximates the intensity of a tornado. "F" stands for the Fujita Scale, with "EF" standing for the Enhanced Fujita Scale. Both rate tornadoes based on engineered wind estimates and damage descriptions. Both F4 and F5 tornadoes are ranked as "intense" and "violent," but the difference between the ratings can only be determined by Doppler Radar data and other technical meteorological measures. See the Wikipedia article linked below for further information and sources. In more detail, an EF4 tornado will level a well built house and blow away ones of with less integrity. An EF5 will wipe well built houses clean off their foundations.

Meteorologists use a radar instrument called Doppler radar to detect tornadoes. Doppler radar can detect the rotation within a thunderstorm, which is a key indicator of possible tornado formation.
