英文摘要	The eastern edge of the western pacific warm pool (wpwp) in the upper layer (shallower than 50m) exhibits significant zonal displacements on interannual scale. employing an intermediate ocean model, the dynamic mechanism for the interannual zonal displacement of the wpwp eastern edge in the upper layer is investigated by diagnosing the dynamic impacts of zonal current anomalies induced by wind, waves (kelvin and rossby waves), and their boundary reflections. the interannual zonal displacements of the wpwp eastern edge in the upper layer and the zonal current anomaly in the equatorial pacific west of 110a degrees w for more than 30 years can be well simulated. the modeling results show that zonal current anomalies in the central and eastern equatorial pacific are the dominant dynamic mechanism for the zonal displacements of the eastern edge of the upper wpwp warm water. composite analyses suggest that the zonal current anomalies induced by waves dominate the zonal displacement of the wpwp eastern edge, whereas the role played by zonal wind-driven current anomalies is very small. a sensitivity test proves that the zonal current anomalies associated with reflected waves on the western and eastern pacific boundaries can act as a restoring force that results in the interannual reciprocating zonal motion of the wpwp eastern edge.
