Tornadoes

Are there any other tornado strength scales in use?

Yes. In Great Britain meteorologists use the TORRO (the TORnado and storm Research Organisation) Scale, which is divided into T0 through T10 measurements of strength. A T0 tornado has winds beginning at 40 miles (64 kilometers) per hour, and a T10 is a “Super Tornado” with wind speeds of 270 to 299 miles (435 to 480 kilometers) per hour.
