Spray from storm in Timor Sea (8)

I believe the answer is:

atomiser

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

'spray' is the definition.
(I know that spray can be written as atomiser)

'storm in timor sea' is the wordplay.
'timor sea' anagrams to 'ATOMISER'.
But, I'm not sure how the anagram is indicated.

'from' acts as a link.

Can you help me to learn more?

(Other definitions for atomiser that I've seen before include "Amortise for spray-creating device" , "Container that releases liquid in a fine spray" , "Perfume spray" , "Fine spray producer" , "Dispenser spraying perfume as a fine mist" .)

I've seen this clue in The Independent.
