Model‐Dependent Atlantic Multidecadal Variability Modulations on North Pacific Sea Surface Temperature Variability and Decadal Prediction

Abstract Previous studies suggested that Atlantic Multidecadal Variability (AMV) modulations on pan‐Pacific sea surface temperature (SST) variability and prediction are model‐dependent. These results were mainly based SST forcing experiments in which AMV‐related anomalies prescribed. However, the AMV itself is also model‐dependent, but its influences Pacific remain unclear. Here, we use multi‐model fully coupled from Coupled Model Intercomparison Project Phase 6 (CMIP6), along with observations, to study model‐dependent trans‐basin effects. We found strength a key factor: Stronger (Weaker) model than observations overestimates (underestimates) response decadal skills, North Pacific. The reason stronger positive phased AMV, for example, leads higher level pressure over Pacific, lifts height deepens thermocline warm SST. Our highlights necessity improve simulations of strength.
