Tempestuous movement split a party (7)

I believe the answer is:

tornado

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

'tempestuous movement' is the definition.
The answer and definition can be both types of natural phenomena as well as being singular nouns.
Perhaps you can see a link between them that I can't see?

'split a party' is the wordplay.
'split' becomes 'torn' (I've seen this in another clue).
'party' becomes 'do' (do is a kind of party).
'torn'+'a'+'do'='TORNADO'

Can you help me to learn more?

(Other definitions for tornado that I've seen before include "Destructive windstorm" , "Destructive weather" , "great deal of wind" , "lot of wind" , "Tempest'" .)

I've seen this clue in The Telegraph.
