摘　　要：基于美国国家海洋大气管理局的最佳插值(NOAA OISST)的海表温度(SST)产品数据(1982—2019年),对南大洋海域38年间海表温度异常(SSTA)的年际变化规律进行了研究,并对SSTA与南方涛动指数(SOI)、厄尔尼诺指数(ONI)进行了相关性分析。其次还研究了南大洋海区SST年际变化规律的空间差异特征。结果显示:在南大洋西南海域(45°S—70°S,120°W—170°W)SSTA与SOI、ONI存在较强的显著相关性,体现了南大洋海域对全球气候变化的响应。基于ONI计算原理,利用该区域SST计算得到南太平洋指数(SPI);通过SPI与厄尔尼诺、拉尼娜事件对比分析,发现该区域SSTA在厄尔尼诺/拉尼娜年份有增加/降低现象,表明该区域与厄尔尼诺/拉尼娜事件可能存在遥相关性。Based on the SST product data(1982—2019) from NOAA OISST,the interannual variation pattern of SSTA over 38 years in the Southern Ocean was studied,and the correlation analysis of SSTA with Southern Oscillation Index(SOI) and El Ni1 o Index(ONI) was conducted.The spatial variation characteristics of the interannual variation pattern of SST in the Southern Ocean Sea area were also investigated,and it was found that there was a strong and significant correlation between SSTA and SOI and ONI in the southwest waters of the Southern Ocean(45°S—70°S,120°W—170°W),which reflects the response of the Southern Ocean sea area to global climate change.Based on the principle of ONI calculation,the South Pacific Index(SPI) was calculated using the SST in this region,and the comparative analysis of SPI with El Ni1 o and La Ni1 a events revealed that the SSTA in this region has increased/decreased in El Ni1 o/La Ni1 a years,indicating that there may be a remote correlation between this region and El Ni1 o/La Ni1 a events.
