Well to me 'blocked' means high pressure on or close to the UK, keeping
Atlantic fronts at bay. Surely if we take Europe as a whole there is
pretty
much always going to be blocking in one place or another.

The centre of high pressure or low pressure blocks can be a 1000 miles
away from UK and we still say (at least where I work) that it is a blocked
situation for the UK. Good grief in winter you get Russian 1050 hPa
anticyclones extending west and we still call it blocked for the UK.
Likewise persistent low pressure over the Azores would give blocked
conditions over the UK. Blocking refers to the general circulation in the
Atlantic basin for the UK. The trouble is we haven't seen *proper* raging
persistent zonality for many many years now in the Atlantic and people are
forgetting what it looks like!

OK, thanks for the explanation.
