AGCM Numerical Simulation on Atmospheric Memory
关于大气“记忆”的大气环流模式模拟研究

Based on numerical simulatin, two AGCMs are employed to study atmospheric memory for sea surface temperature anomalies over eastern equatorial Pacific The results show that atmospheric memory for external forcing is longer than expected The mechanism is that, low-frequency oscillation (atmospheric low-frequency remote response) excited by the external forcing through atmospheric internal dynamic process prolongs the effect of external forcing, therefore, the atmospheric memory becomes longer
