The shading indicates the composite 200-hPa meridional wind anomalies at a lead of 10 days, c lag of 0 days, and e lag of 10 days for observation and for large ensemble historical climate experiment (HIST; b, d, f). Red contours in (f) are from linear baroclinic model (LBM) experiment using June basic state, averaged from 30 to 50 days when LBM integration reached equilibrium. Gray contours show the eigenvectors of HIST first leading mode of interannual 200-hPa meridional wind during June to September (CGT pattern). Dotted regions denote anomalies significant at the 90% and 99% confidence level for the observation and HIST, respectively.
