Fig. 1: Impacts of the two Atlantic Niño types on West Antarctica.
From: Distinct Impacts of the Central and Eastern Atlantic Niño on West Antarctic Sea Ice
a–c Regression of JJA sea ice concentration (SIC, %), surface air temperature (SAT, °C) and 850-hPa wind anomalies (m s−1) on the normalized JJA central Atlantic Niño index (CANI), respectively. d–f Same as (a–c) but for the eastern Atlantic Niño index (EANI). Stippling and black vectors represent anomalies that are statistically significant at the 90% confidence level. Regions marked A (100°W-150°W) in (a, b) denote the primary West Antarctic sea ice regions associated with the central Atlantic Niño (CAN), while regions B (160°W-180°) and regions C (80°W-100°W) in (d, e) represent key sea ice zones linked to the eastern Atlantic Niño (EAN).
