| 英文摘要 | El Ni & ntilde;o-Southern Oscillation (ENSO) is the leading mode of interannual ocean-atmosphere coupling in the tropical Pacific, fi c, greatly influencing fl uencing the global climate system. Seasonal phase locking, which means that ENSO events usually peak in boreal winter, is a distinctive feature of ENSO. In model future projections, the ENSO sea surface temperature (SST) amplitude in winter shows no significant fi cant change with a large intermodel spread. However, whether and how ENSO phase locking will respond to global warming are not fully understood. In this study, using Community Earth System Model Large Ensemble (CESM-LE) projections, we found that the seasonality of ENSO events, especially its peak phase, has advanced under global warming. This phenomenon corresponds to the seasonal difference in the changes in the ENSO SST amplitude with an enhanced (weakened) amplitude from boreal summer to autumn (winter). Mixed layer ocean heat budget analysis revealed that the advanced ENSO seasonality is due to intensified fi ed positive meridional advective and thermocline feedback during the ENSO developing phase and intensified fi ed negative thermal damping during the ENSO peak phase. Furthermore, the seasonal variation in the mean El Ni & ntilde;o-like SST warming in the tropical Pacific fi c favors a weakened zonal advective feedback in boreal autumn-winter and earlier decay of ENSO. The advance of the ENSO peak phase is also found in most CMIP5/6 models that simulate the seasonal phase locking of ENSO well in the present climate. Thus, even though the amplitude response in the winter shows no model consensus, ENSO also significantly fi cantly changes during different stages under global warming. |
