Sea Breeze convergence.
Jack
Thanks for that confirmation - I've been in a head to head on a windsurfing
forum about "sea breezes" for the past couple of years - having lived on the
Coast for quite a few years and observed, all be it, our own "local
conditions" I know that we do have some sort of thermal activity right up to
the end of September.
What is at issue, is the term / definition of Seabreeze and is there a
distinct season - according to some Nautical Weather Handbooks - the
Seabreeze season is only up to mid July!!!
As you probably know I run a streaming weather cam on the Coast here at
Worthing along with a weather station and you can see how the breeze kicks
in - but according to some people this is often "frontal" activity - but
then as I say, it's always a coincidence then that this "front" comes in and
noon with the wind swinging to cross on shore and then dropping and veering
cross offshore at dusk!

We've been having a debate in the windsurfing forums that we are no
longer
in the sea breeze season - can you shed any light on this, and or
clarify
the definition of what constitiutes a "sea breeze?
Glider pilots certainly do not think of the sea breeze convergence season
as
being over just yet.
That convergence on Tuesday showed up well on the satellite pictures.
It always seems quite remarkable how small the land/sea temperature
difference need be for a sea breeze to penetrate inland (even against the
gradient wind, ie produce the convergence) 2 degrees can suffice, but 3
degrees C is perhaps a better rule of thumb. Sea temperatures off
Cornwall
would seem to be quite low this year at only 17 degrees (is this normal?
North Sea is warmer) so 20 degrees inland Cornwall would have been all
that
was needed.
I liked the photo by the way.
