North Atlantic Oscillations as drivers of local climatic variability. Predicted (a) winter total precipitation, (b) winter mean temperature, and (c) winter precipitation (Prec)-potential evapotranspiration (PET) as function of the North Atlantic and the Atlantic Multidecadal oscillations (NAO and AMO, respectively) using generalized linear models (gamma distribution of error and inverse link) in cases a and b, and a linear model in case c. Dependent variables were both centered (y−y mean) for an easier interpretation of colored isoline plots (dotted line represents y mean)
