'sudden inspiration' is the definition.
(I've seen this before)

'in squall following bit of bother' is the wordplay.
'squall' becomes 'storm' (I've seen this before).
'following' means one lot of letters go next to another.
'bit of bother' becomes 'bra' (I can't justify this - if you can you should give a lot more credence to this answer).
'in'+'storm'='instorm'
'instorm' put after 'bra' is 'BRAINSTORM'.

Can you help me to learn more?

(Other definitions for brainstorm that I've seen before include "Generate ideas; mental disturbance" , "in which one's unable to think clearly?" , "Sudden inspiration" , "has such a severe effect on the mind" , "Aberration" .)
