Abstract
The interactive ensemble coupling strategy has been developed specifically to determine how noise impacts climate variability within context of coupled general circulation model (CGCM). This study examines the impacts of local versus non-local noise on the tropical Pacific sea surface temperature anomaly (SSTA) variability using three CGCM simulations. The control run uses the standard coupling strategy. In the first experiment, the interactive ensemble strategy is applied globally thereby reducing the noise at the air-sea interface at each grid point. In the second experiment, the interactive ensemble strategy is applied locally in the tropics only. By directly comparing the three CGCM simulations we investigate a role of local versus non-local noise on the ENSO statistics. Preliminary result indicates that a non-local noise in the North Pacific Perhaps has a minor impact on the ENSO statistics including the frequency and amplitude.
