GOALS-2 and GOALS-4) developed at State Key Laboratory of Atmospheric Sciences and Geophysical Fluid Dynamics (LASG), are validated in terms of the simulations of the winter North Atlantic Oscillation (NAO), which is currently the subject of considerable scientific interest. The results show that both GOALS-2 and GOALS-4 exhibit a realistic NAO signal associated with relatively reasonable spatial patterns of sea level pressure, surface air temperature, and precipitation. Generally speaking, the associated ...

1. IntroductionThe North Atlantic Oscillation (NAO) is a large--scale alternation of atmospheric masswith centers of action near the Icelandic low and the Azores high. It is the dominant mode ofatmospheric behavior in the North Atlantic sector throughout
