Abstract: We study the temporal correlations in the sea surface temperature (SST) fluctuations around the seasonal mean values in the Atlantic and Pacific Oceans. We apply a method that systematically overcome possible trends in the data. We find that the SST persistence, characterized by the correlation C(s) of temperature fluctuations separated by a time period s, displays two different regimes. In the short-time regime which extends up to roughly 10 months, the temperature fluctuations display a non-stationary behavior for both oceans, while in the asymptotic regime it becomes stationary. The long-term correlations decay as C(s)∼s−γ with γ∼0.4 for both oceans which is different from γ∼0.7 found for atmospheric land temperature.
