A tornado with estimated winds of 100 mph would be rated EF1.
A tornado with peak estimated winds of 100 mph would be rated F1 on the Fujita scale.
A tornado with estimated winds of 120 mph would be rated EF2.
EF1, estimated winds were 100 mph
If you mean can a 15-20 mph wind then no. In fact there is strong evidence to support that strong winds from a specific portion of a thunderstorm are what help form a tornado. These winds can exceed 100 mph.
Tornado damage is mostly the result of powerful winds. Tornadic winds can easily exceed 100 mph and have been recorded in excess of 300 mph. The force of such wind can damage if not destroy buildings and trees.
It is impossible to know exactly how fast the winds were as we did not have the tools to measure a tornado's winds back then. But since the tornado was rated F5 (equivalent to EF5 on the new scale) winds were probably well over 200 mph.
The winds in a tornado can vary greatly and be any where between 65 and 300+ MPH. The majority of tornadoes have winds of 110 mph or less while the most damaging have estimated winds over 135 mph.
Not necessarily. Officially, winds for an EF0 tornado start at 65 mph, and some tornadoes in recent years have been rated with winds as low as 55 mph. This is still sufficient damage trees and some weak structures. By definition, a hurricane must have sustained winds of at least 74 mph.
Estimated winds in a tornado can range from speeds as low as 65 mph to over 300 mph.
No, tornadoes typically have wind speeds much higher than 74 mph. Tornado wind speeds can range from 65 mph to over 300 mph, with stronger tornadoes capable of producing winds over 200 mph. A tornado with 74 mph winds would likely be considered a weak tornado.
Winds range can range from 65mph to over 300mph. Most tornadoes are rated EF0 with estimated winds of 65mph to 85 mph. The greatest damage comes from EF3 and stronger tornadoes with winds over 135 mph. Few than 1 tornado in every thousand is rated EF5, with winds over 200 mph.
The Enhanced Fujita scale puts the beginning of tornado winds at 65 mph. Doppler radar has detected winds in a tornado of just over 300 mph.
