Tropical Cyclone and Tornado Wind Speed Equivalence : meteorology

1 min read

Context: Hurricane Dorian made landfall with wind of around 185 mph in the Bahamas. From this video (Hurricane Dorian by iCyclone, link:, I can see most cars are smashed by debris but not overturned, windows are not completely blown off, and the building seems damaged but not completely destroyed. But 185 mph for a tornado (enough for EF-4) would blow the windows, overturn cars and the building in the video would mostly be unsafe to stay in (Considering situations like Mayfield 2021, and Louisville 2014). And yes, people in the video would not likely survive if they stay in that room.

My question is Why tornadoes and hurricanes’ damage are not the same even when they have similar wind speed? Also, if a tornado were to have 300 mph, what wind speed would be required to produce similar damage from a hurricane?

Note: I am talking about wind damage, no storm surge, and no flooding.
