Recent analyses using high-spatial-resolution data reveal that sea surface temperature variability in western boundary currents significantly impacts local climate variability, more than previously understood.
Warm sea surface temperature anomalies in major boundary currents are linked to notable precipitation and rising motion anomalies throughout the troposphere, demonstrating oceanic impact on weather patterns.
Our research uncovers a clear pathway where ocean dynamical processes within the boundary currents actively influence climate variability, contrasting with earlier findings about internal atmospheric variability.
High-resolution Earth system model simulations validate the observational data, indicating that the ocean dynamics considerably shape local climate responses, emphasizing the need for detailed modeling.
