7 Beaufort wind

Finistere, Bretagne, France.

The Beaufort Scale ( /ˈboʊfərt/) is an empirical measure for describing wind speed based mainly on observed sea conditions (on land it is categorised by the physical effects it has on vegetation and structures). Its full name is the Beaufort Wind Force Scale.
