Abstract
Based on the monthly sea surface temperature (SST) data provided by Hadley Centre, the characteristics of Southern Subtropical Atlantic SST variation and its relationship with ENSO are discussed. The results of this paper show that: 1) In the summer of the southern hemisphere, the SST anomaly (SSTA) of the Southern Subtropical Atlantic presents a southwest-northeast antiphase dipole modes, that is, the South Atlantic Subtropical Dipole (SASD), which develops from September to November. It reaches its peak in austral summer(December January February, the next year), weakens from March to May (the next year), and declines until austarl winter(June July August, the next year). 2) SASD is significantly correlated with ENSO, and positive SASD and negative SASD are correlated with El Niño and La Niña events respectively.
