Tornadoes have been confirmed with winds as low as 60 mph. Below that it is debatable as to whether a funnel is a tornado, as winds under 58 mph are not considered severe.
by their windspeed
The wind speed for Waco Tornado was over 250 mph winds.
The lowest rating a tornado can receive is EF0.
The lowest known pressure recorded in a tornado was 688 millibars in a tornado in Tulia, Texas on April 21, 2007.
Yes the pressure drops as the tornado forms and progresses. The tornado's lowest pressure is in the center.
States with lowest tornado incidences include Alaska, Hawaii, and Vermont. These states typically have cooler climates and are not located in the traditional tornado alley region of the United States.
Pressure decreases sharply, reaching its lowest at the center of the tornado. This pulls air toward the center of the tornado and then drawn into the tornado's updraft. The tornado spins as it originates from a larger circulation called a mesocyclone.
Windspeed
WindSpeed
The relationship between time and windspeed can vary. Windspeed can fluctuate over time due to changing weather patterns and atmospheric conditions. Generally, windspeed can increase or decrease over time in response to various factors such as temperature gradients, pressure systems, and the time of day.
The mode of the windspeed of 40 kph is 40 kph, as it is the value that appears most frequently in the dataset.
No one really know pressure can vary for the type or category of a tornado.
