Douglas Sea scale

[[2574]]

I've just found, via Simon's weather site, (http://www.weatherweb.net/swis.htm) a link to the "Douglas Sea scale" which I'd previously never heard of. I'd often wondered what "slight" or "moderate" was defined as and now I know:

A useful read.

You can find it on the Met Office website glossary.
