Abstract

Abstract

The temperature anomalies lag relationship between whole south Indian Ocean and the upper welling region of the southwest tropical Indian Ocean is investigated using the Simple Ocean Data Assimilation (SODA) oceanic reanalyses. The results indicate that the signal of temperature anomalies propagates from high latitude to low latitude along thermocline in the southeast Indian Ocean. It is found that the atmospheric perturbation drive the signal in the ocean located around 65°S, 105°E at the beginning, then it reaches to southeast Indian Ocean after about 10 a. The possible reason is also discussed in this study．
- southeast Indian Ocean,
- meridional propagation,
- decadal oscillation,
- upper welling region in the southwest Indian Ocean
