AO and NAO - NHEMI Air Temperature Variability

Winter Northern Hemisphere surface air temperature variability
associated with the Arctic Oscillation and North Atlantic Oscillation

"The paper shows that the NAO and the AO have different impacts on winter NH (surafce air temperature) SAT. The variability of other atmospheric variables related to the AO and the NAO is discussed."

A bit wonkish...but a still a good read.
