This study investigates the impact of Atlantic multidecadal variability (AMV) on seasonal prediction skill for sea surface temperature anomalies in the subtropical North Atlantic.
Combined observational data and ensemble hindcasts
Examined seasonal prediction skill of sea surface temperature anomalies
Analyzed variations in upper-ocean heat content related to AMV phases
Spring sea surface temperature anomaly prediction skill is significantly higher during AMV positive phase compared to negative phase (p<0.05)
Higher SSTA persistence is observed in AMV positive phase
Variations in upper-ocean heat content are linked to the Atlantic Meridional Overturning Circulation's heat convergence patterns.
