a The ensemble mean of 50°W–10°W averaged climatological precipitation (m, CMIP6). b–g Ensemble mean of composited sea surface temperature (SST, shading, °C, only values exceed 95% significance level are given, CMIP6), surface wind (vector, m/s, black vectors exceed 95% significance level, CMIP6), and precipitation (contour, interval is 5 × 10−4 kg/m2/s, red solid and blue dashed lines for positive and negative, CMIP6) from 27 CMIP6 historical simulations for Equatorial and Expanded types of Atlantic Niño events in December−1-January0-February0 (DJF0, where −1, 0, and 1 represent the preceding, current and subsequent year of the winter Atlantic Niño peak season), March0-April0-May0 (MAM0) and December0-January1-February1 (DJF1) seasons. The influences of DJF0 El Niño-Southern Oscillation (ENSO) have been removed before the composite analysis.
