I think it's better if the wind in beaufort is in decimal form and covers winds greater than 12 Beaufort. (e.g. 12.0-12.9 Beaufort =hurricane cat1.0-1.9 etc). I'm sending to you my own code that I use in my own programs if it helps.There is programs that use Beaufort at decimal form and beyond 12 Beaufort velocities.

I think the colors of temperatures must change.
For example the colors from 0 to -20 are almost the same.
