Circulation of trouble-free newspaper led by senior journalist (4)

I believe the answer is:
eddy
'circulation' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'trouble-free newspaper led by senior journalist' is the wordplay.
'trouble-free newspaper' becomes 'dy' (I can't justify this - if you can you should give a lot more credence to this answer).
'led by' is a charade indicator (letters next to each other) (some letters go in front of others).
'senior journalist' becomes 'ed' (abbreviation for editor).
'dy' after 'ed' is 'EDDY'.
'of' is the link.
Can you help me to learn more?
(Other definitions for eddy that I've seen before include "dangerous bit of water" , "Whirlwind" , "Miniature whirlpool" , "(Of fluid) circle round" , "Boy" .)
