Blow that has to be faced (8)
I believe the answer is:
headwind
'blow that has to be faced' is the definition.
The answer and definition can be both types of natural phenomena as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'blow that has to be' is the wordplay.
'blow' becomes 'wind'.
'that has' means one lot of letters go next to another.
'to be' becomes 'head' (heading is a kind of being).
'wind' put after 'head' is 'HEADWIND'.
Can you help me to learn more?
(Other definitions for headwind that I've seen before include "Current of air blowing into the bow of ship" , "It blows straight into your face" , "Stiff breeze blowing directly in front" , "Contrary breeze" , "opposing force" .)
