Fig.3 The composite anomaly field of 500 hPa geopotential height (color shaded area, Unit: gpm) and 700 hPa wind field (arrows, Unit: m·s-1) in winter of positive (a) and negative (b) anomaly of AO index (The black dot areas for geopotential height anomaly and the blue arrows for wind vector anomaly passed the significance test at 0.05 level (the same as below))
