Atlantic impacts on subdecadal warming over the tropical Pacific in the 2000s
Introduction A subdecadal (i.e. , three-year running mean) variation over the tropical Pacific is very distinctively observed in the 2000s. Results and methods Here, we have demonstrated that sea surface temperature (SST) anomalies in the tropical Atlantic contribute to forming high ocean-temperatur...
