I am actually providing two solutions to the problem here. They
can't both be wrong!

Cheers, Alastair.


Unfortunately I think they are in this case-as splitting starts over the
open ocean.

Oh well, third time lucky. Look at it this way; you have a prevailing
south westerly flow over the British Isles. Thus the air mass first
hits Kerry in the south west of Ireland where it has to rise a few
hundred feet. As it travels further north eastwards, it eventually
reaches Fort William where Ben Nevis takes it to over 4000 feet.
Now if that air mass was a stunt motor car with its right wheels
being raised by a factor of ten (huh?) then it too would probably
roll over into the Atlantic, just as the air mass does! Or does it
roll the other way :-?

Cheers, Alastair.
