| 摘 要： | 基于NOAA重建的海面温度（sea surface temperature, SST）资料和NCEP再分析大气资料，研究了ENSO（El Niño-Southern Oscillation）与南海SST关系的年代际变化。结果表明：ENSO影响南海SST的冬、夏季“双峰”现象发生了显著的年代际变化，即冬季的“峰值”自20世纪80年代显著减弱，而夏季的“峰值”稳定持续且在20世纪70年代之后增强；冬季“峰值”的减弱可能与冬季西北太平洋反气旋的年代际变化有关，夏季“峰值”的维持和增强可能与20世纪70年代之后印度洋SST“电容器”效应的增强有关。

| Abstract: | Based on the reconstructed SST (sea surface temperature) data from NOAA and atmospheric reanalysis data from NCEP, the interdecadal variability of the relationship between ENSO (El Niño-Southern Oscillation) and SCS (the South China Sea) SST is studied. It is found that the anomalous SCS SST double peak structure affected by ENSO in winter and summer has undergone significant interdecadal variability, that is, the winter peak has weakened significantly since the 1980s, while the summer peak remains stable and has been enhanced since the 1970s. The weakening of the winter peak may be related to the interdecadal variability of the western North Pacific anticyclones in winter, and the maintenance and enhancement of the summer peak may be associated with the enhancement of the capacitor effect of SST over the Indian Ocean after the 1970s. |
