Wind of southern France (7)
I believe the answer is:
mistral
'wind of southern france' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for mistral that I've seen before include "Strong north wind of southern France" , "Violent northeast wind of southern France" , "A harsh blow" , "Famous wind in the Rhone Valley blowing towards the Med" , "Cold dry wind in southern France" .)
