Season‐Dependent Atmosphere‐Ocean Coupled Processes Driving SST Seasonality Changes in a Warmer Climate
Abstract Amplification of sea surface temperature (SST) seasonality in response to global warming is a robust feature in climate model projections but season‐dependent regional disparities in this amplification and the associated mechanisms are not well addressed. Here, by analyzing large ensemble s...
