(a) Simultaneous correlation between I_W and the meridional vertical circulation averaged over 90–100°E. (b) Composite anomalies of the meridional vertical circulation averaged over 90–100°E between the high-I_W and low-I_W years. The dark (light) shading in (a) indicates the correlation coefficients significant at the 99% (95%) confidence level. The shading in (b) indicates the meridional vertical circulation anomalies significant at the 95% confidence level.
