Something inclined over a long time to produce storms (8)
I believe the answer is:
rampages
'storms' is the definition.
(I've seen this in another clue)
'something inclined over a long time' is the wordplay.
I cannot really see how this works, but
'a' could be 'amp' (A is the symbol for the amp or ampere) and 'amp' is present in the answer.
'time' could be 'ages' (ages can informally mean a long period) and 'ages' is located in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'to produce' is the link.
Can you help me to learn more?
(Other definitions for rampages that I've seen before include "Violent disorders" , "Moves through a place in a violent and uncontrollable way" , "Rushes around wildly" , "Violent and destructive behaviours" , "runs wild" .)
