中文摘要	Intra-seasonal variability of sea level anomalies (SLAs) originated in the Pacific Ocean around the Philippine Archipelago was investigated using merged altimetry SLA measurements and eddy-resolving ocean model outputs. The results suggest the SLA signals from the tropical North Pacific propagate westward as baroclinic Rossby waves on an intra-seasonal time scale. Upon impinging the east coast of the Philippines, these Rossby wave signals transform into coastal trapped waves (CTWs), propagate clockwise along the coast of the Philippine Archipelago and enter into the eastern South China Sea (SCS) through the Sibutu Passage and Mindoro Strait. The SLA signals, however, cannot propagate anticlockwise and enter into the eastern SCS through the Luzon Strait. The intra-seasonal oceanic wave processes are clearly identified by the eddy-resolving model. The effect of along-shore wind forcing on the SLA signals appears insignificant when compared with the remote signals coming from the interior Pacific. While identified in the model simulation, future observations are needed to verify the intra-seasonal CTWs encircling the Philippine Archipelago.
