Rain-bringing wind (7)
I believe the answer is:
monsoon
'rain-bringing wind' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for monsoon that I've seen before include "'Seasonal wind in southern Asia, brings heavy rains (7)'" , "Seasonal Indian Ocean wind" , "Season of heavy rain" , "Seasonal wind or rainy season in S Asia" , "Rainy season in southern Asia" .)
