Abstract: The first evidence of asymmetric upward and downward persistence in the global sea surface temperature anomaly (SSTA) is revealed from the observations with the asymmetric detrended fluctuation analysis (A-DFA) method. Global distributions of the scaling exponents which quantify the degree of memory on time scales in the range from 10 months to 20 years, show that the strong general long-term persistence of SSTA forms a thwartwise letter “V” over the tropical Pacific Ocean. The strong upward and downward long-term persistence only exists in particular half of the letter “V”.
