A little change in weather: wind (7)
I believe the answer is:
wreathe
'wind' is the definition.
(I know that wind can be written as wreathe)
'a little change in weather' is the wordplay.
'a little change in' indicates an anagram.
'weather' anagrammed gives 'WREATHE'.
(Other definitions for wreathe that I've seen before include "(E.g smoke) curl" , "Twist together" , "Intertwine, curl round" , "Surround, encircle" , "Weather (anag.)" .)
