An alternative tornado scale.

I will do lots of research.

There will be fourteen categories from TC0 to TC13.

Temporary wind speeds:

TC0: 0 to 19 miles per hour

TC1: 20 to 41 miles per hour

TC2: 42 to 63 miles per hour

TC3: 64 to 89 miles per hour

TC4: 90 to 113 miles per hour

TC5: 114 to 137 miles per hour

TC6: 138 to 161 miles per hour

TC7: 162 to 183 miles per hour

TC8: 184 to 205 miles per hour

TC9: 206 to 237 miles per hour

TC10: 238 to 255 miles per hour

TC11: 256 to 277 miles per hour

TC12: 278 to 299 miles per hour

TC13: 300+ miles per hour

I will add more information (such as damage factors, accountancy for construction quality, and so on).
