Arctic-Mid-Latitude Linkages in a Nonlinear Quasi-Geostrophic Atmospheric Model

Figure 7

PC time series corresponding to the first EOFs of geopotential height at the three model levels: upper level (a), middle level (b), and lower level (c). The numbers display the mean of the corresponding PC series for the 50-year-long time series. Red and blue colors correspond to the model runs with high and low Arctic sea-ice-cover conditions, respectively.
