Impacts of Northwest Pacific anomalous anticyclone on sea surface height and circulation

yanping SHI

Abstract


In this study, we investigate the northwest Pacific anomalous anticyclone (NWPAC) associated with Indian Ocean W Arming and its impacts on ocean circulation and sea surface the height in the northwest by using the Pacific Wind, Current and sea surface height data of national Centers for Environmental Prediction (NCEP) and SODA v2.2.4 during the IoD of 1971 to 2010. Composite results reveal that NWPAC associated with Indian Ocean warming is the strongest during the boreal summer and It has significant impacts on the upper-ocean circulation and sea surface the height in the NW Pacific. The anticyclonic wind anomaly produces a negative wind stress curl, inducing convergence of sea surface water and the ResU Ltant positive sea level anomalies. The effect of Nwpac on the Upper-ocean circulation in the South our sea is synchronous, while its impact on the upper OC Ean east of the Philippines delays by about one season and peaks in the boreal
