摘要

采用国际海—气综合数据集(The International Comprehensive Ocean-Atmosphere Data Set, ICOADS)船舶观测资料及简单海洋同化分析数据(Simple Ocean Data Assimilation, SODA), 研究了厄尔尼诺(El Niño-Southern Oscillation, ENSO)和印度洋海盆模态(Indian Ocean Basin, IOB)对南海海表温度(sea surface temperature, SST)影响的年代际变化, 并着重讨论了不同时期海洋平流输送对SST异常的影响。结果表明, ENSO事件对南海SST的影响呈现显著的年代际变化特征; 在1870~2007年期间, 扣除资料较少的时期, 有4个显著不同的时段, 分别是1892~1915年、1930~1940年、1960~1983年、1984~2007年。在1950年之前的两个时段, 南海在ENSO期间出现一次显著的增暖, 而在1950年之后的两个时段中, 南海出现了两次显著的增暖。除第一个时段外, 其余三个时段ENSO发展期冬季大气潜热及短波辐射异常是导致南海增暖的主要原因, 海洋平流作用较弱; 而在最近的两个时段中, 海洋平流对ENSO消亡年夏季南海增暖有重要影响。不同时段海洋平流对南海增暖贡献的差异说明ENSO及IOB对南海区域气候的影响具有明显的年代际变化特征。

Abstract

Using the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) and Simple Ocean Data Assimilation (SODA) reanalysis, this study investigates the decadal variability of sea surface temperature (SST) over the South China Sea (SCS) associated with El Niño-Southern Oscillation (ENSO) and Indian Ocean Basin (IOB) mode. Four epochs during 1870-2007 were identified with significant differences. The SST anomalies showed single peak of warming during the periods before the 1950s, and double peaks of warming after the 1950s. The results of ocean heat budget indicated that the oceanic advection anomalies contributed little to the SCS warming in an ENSO developing year during Epochs 2, 3 and 4. The SCS warming was mainly due to the latent heat flux and shortwave radiation anomalies associated the ENSO. However, the SCS warming in the summer of an ENSO decay year could attribute to oceanic advection during the periods after the 1950s. The different contributions of oceanic advection to the SST warming in the past 138 years indicated that the ENSO teleconnection to the SCS climate experienced decadal changes.

Key words： ENSO; Indian Ocean Basin; South China Sea SST; oceanic advections; decadal variability
