Munro snubs a top high-flyer in the Alps? (3,6)

I believe the answer is:

ski jumper

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

'high-flyer in the alps?' is the definition.

'munro snubs a top' is the wordplay.
'munro snubs' becomes 'ski' (I can't explain this - if you can you should give a lot more credence to this answer).
'a top' becomes 'jumper' (I've seen this before).
'ski'+'jumper'='SKI-JUMPER'

Can you help me to learn more?

(Other definitions for ski jumper that I've seen before include "Winter sportsman" , "Winter sportsperson" , "Winter leaper" , "Winter sport ace" , "Sporty type" .)

I've seen this clue in The Guardian.
