a The anomalous E-P flux (vectors; m3s−2) and its divergence (shaded; m2s−2) in November, b–d Same as a, but for December, January, and February, respectively. Pink dots indicate the anomaly that passes the significance test at a 95% confidence level. E-P flux anomalies less than 0.5 × 104 m3s−2 are discarded from the plot.
