Fig. 2: SSTA tendencies during ENSO events.
From: Key to ENSO phase-locking simulation: effects of sea surface temperature diurnal amplitude
a, b SSTA tendencies in observations and Small DA models in CMIP6 during El Niño (a) and La Niña events (b). Thin gray lines are the tendencies in each CMIP6 model, and the thick black line represents the ensemble mean. c, d Same as (a, b), but for Large DA models in CMIP6. e, f Biases in the mean SSTA tendencies in CMIP6 models compared with observations during El Niño (e) and La Niña events (f). Standard errors of the mean represent the 95% confidence intervals. The gray bands in (a–d) represent boreal winter.
