'how a dry summer regularly attracts northern chaps catching crabs?' is the definition.
I can't tell whether this defines the answer.

'how a dry summer regularly attracts northern' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'attracts' means one lot of letters go next to another.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'how'+'a'+'dry'+'summer'='howadrysummer'
The alternating letters of 'howadrysummer' are 'oarsme'.
'oarsme'+'n'='OARSMEN'
