The Atlantic Meridional Mode (AMM) is the dominant mode of interannual climate variability in tropical Atlantic, maintained primarily by positive wind–evaporation–sea surface temperature (SST) feedback which wind anomalies lead SST ~2 months. A previous study revealed that models from Coupled Model Intercomparison Project Phase 5 (CMIP5) show poor performance simulating AMM-related wind–SST relationship, but possible causes remain unclear. This assesses representation AMM and associated...
Abstract Recent studies suggest that tropical Indian Ocean sea surface temperature (SST) anomalies, especially those associated with the Dipole (IOD), may trigger Atlantic Niño through atmospheric teleconnection. However, it remains unclear whether former has an impact on prediction skill of latter. This work applies hindcasts from 21 operational seasonal forecast systems based dynamical climate models to verify IOD in boreal autumn predictive following winter. The results indicate skills...
