Completed Tornado Diagram. Tornado diagrams, also called tornado plots, tornado charts or butterfly charts, are a special type of Bar chart, where the data categories are listed vertically instead of the standard horizontal presentation, and the categories are ordered so that the largest bar appears at the top of the chart, the second largest appears second from the top, and so on.

For comparison, the strongest detected winds in a United States tornado (during the 1999 Oklahoma tornado outbreak) would be T11 using the following formulas: v = 2.365 (T+4) 3/2 m/s v = 8.511 (T+4) 3/2 km/h v = 5.289 (T+4) 3/2 mph v = 4.596 (T+4) 3/2 kn. where v is wind speed and T is TORRO intensity number. Wind speed is defined as a 3-second ...
On May 6, 2023, version 0.99.9d was published, which changed it to a 9-step rating scale. [3] In this version, the wind speed damage indicator was introduced, which made it the first tornado intensity and damage scale to use measured wind speeds and Doppler weather radar measured wind speeds. [ 3 ]
The higher the BTI value is, the more likely a tornado is on the ground. Shear markers from different colors are used depending on the scale above 2. Yellow markers are used for values between 2 and 3.9, Orange markers are used for values between 4 and 6.9 and red markers are used for values over 7. [1] [2] [3] [4]
