There is much evidence, certainly for Atlantic fringes of the UK, of far less gales this century compared with the norm for the 20th. This may be due to the reduced N - S temperature gradient, certainly near the surface (though the atmosphere is 3D).


There has been a downward trend in the winter NAO since the turn of the
century, which is related to a decrease in storminess (winter 2013/14
excepted), and an increase in the frequency of cold winters (who would
have thought we could get three consequtive cold winters 2008/9,
2009/10, 2010/11, 20 years ago).

There is evidence that summer Greenland blocking has increased in
frequency over the last 20 years, which is connected to the frequency of
poor summers (cloudy and wet, if not cool) since 2007.
