Decadal climate variability in the southern Indian Ocean could be predicted up to 10 years ahead, according to a study led by Dr. MORIOKA at Application Laboratory, the Japan Agency for Marine-Earth Science and Technology (JAMSTEC: ASAHIKO Taira, President) and his colleagues. To investigate the predictability, the scientists have used sea surface temperature (SST) observation data during 1982 to 2015 to initialize a state-of-the-art coupled general circulation model, the Scale Interaction Experiment Frontier Research Center 2 for Global Change (SINTEX-F2*) with a simple SST-nudging scheme. Their decadal reforecast experiments demonstrated moderately high prediction skills of yearly mean SST in the southwest Indian Ocean at 10-year lead time.
