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

'storms' is the definition.
The definition and answer can be both types of natural phenomena as well as being plural nouns.
Maybe they are linked in a way I don't understand?

'destroyed roots and' is the wordplay.
'destroyed' indicates an anagram.
'roots'+'and'='rootsand'
'rootsand' anagrammed gives 'TORNADOS'.

'made' is the link.

Can you help me to learn more?
