a Regression of JJA 200-hPa geopotential height anomalies (GPH, shading, m) and wave activity fluxes (WAF, vector, m2 s−2) on the normalized JJA CANI. b Same as (a) but for the EANI. Black contours denote GPH anomalies that are statistically significant at 90% confidence level. The magenta (green) line represents the wave train propagation pathway generated by the direct (indirect) impact of Atlantic Niño on Antarctica.
