You are not surely claiming *Graham that it is milder in Cornwall
compared with Swindon in winter because of the N.Atlantic drift?!
It is simply because of Cornwall's proximity to the N.Atlantic and is
surrounded by sea that it is milder!

It's certainly a factor. Just look at maps of winter air & sea
isotherms. The sea is particularly warm off the west coast of the UK
because of the N Atlantic Drift. *The strength of the prevailing
westerly determines how far the influence stretches eastwards. In the
case of this January, about as far as the Tamar!

Swindon is also benefitting from the little bit of extra warmth from
the N. Atlantic drift.The wind does not stop at the Tamar valley.
But Cornwall is really benefitting from its proximity to the sea,
irrespective of any currents.
