The following quote is taken from an article by an F.E. Lumb. Sorry
that I
do not know the exact source but it is some kind of meteorological
journal
from the 1980s.

My question is: do the isotherms, and particularly the tongue of
warmer
water in the channel, still exist?

.... see the thread entitled: "Comparison of SST's: current and
historic": follow the links in that thread (at the bottom of the
original post) for a couple of maps that show that the tongue of warmer
water is still the for latest information, see:-
http://www.wetterzentrale.de/pics/brack5.html

I assume that the steady west to east current up the Channel is
responsible for the 'plume' of relatively warmer water - but I'm not an
oceanographer, so this statement might be corrected.

Martin.
