I believe the answer is:

squalls

I'm a little stuck... Click here to teach me more about this clue!

'screams' is the definition.
('squall' can be a synonym of 'scream')

I don't understand the remainder of the clue.

(Other definitions for squalls that I've seen before include "Yells" , "Blustery winds" , "Sudden violent winds" .)

I've seen this clue in The Globe and Mail.
