南海海温在两类El Niño衰退期的季节响应差异

Abstract

Abstract:

This study suggests that the sea surface temperature (SST) in the South China Sea (SCS) has different temporal and spatial characteristics in response to the eastern Pacific (EP) El Niño and central Pacific (CP) El Niño. Temporal features are consistent with previous research: the warm SST anomalies located in the SCS during winter of the developing year and summer of the decaying year of El Niño. As for spatial features, the first significant warming peak is confined to the west of 115°E for EP El Niño events, then the warm SST anomaly center propagate to the eastern SCS, and the second warming peak is located to the east of 110°E. But the double warming peaks are limited to the west of 115°E for CP El Niño events. Different wind anomaly fields during the summer of the decaying year of the two types of El Niño led to different locations of the warm SST anomalies in the SCS. Further physical mechanism analysis show that the second significant warming of the SCS SST during the EP El Niño is associated with the India Ocean basin mode, while the second warming during the CP El Niño is under the influence of the CP El Niño.
