If you’re wondering why you’ve never heard of it, it is apparently only used in the UK. It’s like us refusing to adopt the metric system.

I don't know, I may actually like their scale better. It amuses me that I've never heard of it until today, which I guess means I didn't learn much about British meteorology in school.

Giving it a once-over, it seems pretty useless. It's basically a warmed-over Beaufort scale (which is itself pretty silly—in the US we just use direct wind speed numbers rather than faffing about with a scale). They say it's better than Fujita because it is a direct wind speed scale and doesn't rely on damage ratings like Fujita does. But tornadoes are so relatively narrow that the odds that any given tornado will directly strike an anemometer are very low (and the odds the anemometer survives long enough to record an accurate wind speed even lower) that, in practice, it functions as a damage scale anyway, just without the defined damage assessment rubric that Fujita is based on. (And British tornadoes are weak enough that the upper reaches of the scale have never been used, so anyone attempting to assign one of them would basically be on their own.)
