A heated blow! (7)
I believe the answer is:
sirocco
'a heated blow' is the definition.
The answer and definition can be both types of natural phenomena as well as being singular nouns.
Maybe there's a link between them I don't understand?
This is all the clue.
Can you help me to learn more?
(Other definitions for sirocco that I've seen before include "Wind from the desert" , "Hot wind that blows across the Mediterranean" , "Hot wind reaching Italy from Africa" , "Hot south wind from North Africa" , "Hot air" .)
