Figure 3 a Summer 200-hPa geopotential height gpm, contours and 850-hPa wind m s -1 , arrows anomalies regressed by the summer precipitation dipole, in which the shaded areas denote geopotential height anomalies significant at the 95% confidence level. b is the same as a, except it shows the results regressed by the interannual variation of the summer precipitation dipole.
