Fig. 3: Composite of D0JFM1 WAF (left) and 300-hPa wind and SF anomalies (right) for the strong and weak MWAF groups as well as the differences between groups.
From: Part II model support on a new mechanism for North Pacific Oscillation influence on ENSO
a The 300-hPa WAF for NPO events in the strong MWAF group. b The 300-hPa WAF for NPO events in the weak MWAF group. c The difference between the strong and weak MWAF groups. d, e Composite difference of D0JFM1 300-hPa wind (unit: m/s) and SF (unit: 106 m2 s−1) anomalies between positive and negative NPO events for the strong and weak MWAF groups, respectively. f The difference of 300-hPa wind and SF anomalies between the two groups. The shading in the left panel represents the MWAF, whereas it is the SF in the right panel. The vectors are shown only with the zonal wind above 90% confidence level, and the dots represent the areas of SF above 90% confidence level.
