Does anyone know of any good references/reports that describe the
influence of Greenland blocking and its influence in the summer months
on the UK weather? I understand that a blocking high over Greenland
results in a trough in the jet over the UK but need to understand how
that relates to rainy, unsettled summer weather (e.g. 2007 and 2012). Am
I correct in thinking that Greenland blocking in summer is associated
with a negative NAO, and that wet UK summers tend to occur with a
negative NAO, and dry UK summers are associated with a positive NAO, a
northerly displaced jet and frequent ridging of high pressure from the
Azores high over the UK?

I am giving a presentation in a month about UK weather, climate and
evidence/projections of climate change and want to make sure I have my
facts correct, I understand what is going on and I am objective.
