Joe (or anyone else)
Could you tell me what exactly a Mile's extension is please?
I heard it mentioned last winter sometime by Will.
I notice 18z is very different, but still very cold - the low in the
Norwegian Sea seems to be the main difference...very interesting!
Ta,
John
Hi John,
Mile's extension is a plunge of cold air south over the UK in response to
warm
advection north over Greenland. I'm sure Will can explain better. Sadly
Google
brings nothing up on the subject.
