通过对 80年代赤道太平洋地区海表水温 (SST)资料及欧洲中期数值天气预报中心(ECMWF)大气资料的分析 ,发现热带大气低频振荡 (LFO ,包括季节内振荡及半年尺度以内的大气振荡 )与赤道太平洋SST异常存在反相变化特征 ,SST正异常对应弱的大气低频振荡 ,SST负异常对应强的大气低频振荡 .相关场分析进一步证实了这种负相关 ,并指出印度尼西亚地区大气低频振荡的异常对赤道中东太平洋SST变化起着很重要的作用 .
Based on the SST data of the equatorial Pacific Ocean in the 1980s and the atmospheric data of the European Midwestern Numerical Weather Prediction Center (ECMWF), it is found that the low-frequency oscillations of the tropical atmosphere (LFO, including intraseasonal oscillations and atmospheric oscillations within a half year scale) The SST anomalies in the equatorial Pacific have reversal characteristics, positive SST anomalies corresponding to weak atmospheric low-frequency oscillations and negative SST anomalies corresponding to strong atmospheric low-frequency oscillations. Correlation field analysis further confirms this negative correlation and points out the anomalies of atmospheric low-frequency oscillations in Indonesia It plays a very important role in the SST changes in the equatorial central and eastern Pacific.
