Is getting a round in the pub for the meteorologists (6)
I believe the answer is:
isobar
'pub for the meteorologists' is the definition.
I can't tell whether this defines the answer.
'is getting a round in the' is the wordplay.
'getting' says to put letters next to each other.
'a round' becomes 'o' (round can mean a round object).
'in the' becomes 'bar' (I am not sure about this - if you are sure you should believe this answer much more).
'is'+'o'+'bar'='ISOBAR'
Can you help me to learn more?
(Other definitions for isobar that I've seen before include "Map-line showing places with equal air pressure" , "Barometric curve" , "Contour" , "It connects points of equal air pressure" , "Weather map feature" .)
