摘要：

Tide gauge data are used to investigate sea level variability off the northwest coast of the South China Sea(SCS) in 2012,and a significant sea level elevation with a magnitude approaching 79 mm is observed.Analysis suggests that an abnormal sea surface heat flux and freshwater flux may have contributed to this abnormal rise in sea level,together with the remote influence of an ENSO event.Further investigation shows that the event was dominated by the positive freshwater flux,where large volumes of water entered the ocean,and a maximum is centered to the south of Guangdong province,China.Simultaneously,a positive anomalous heat flux occurred in the northwestern part of the SCS,which is considered to have made a positive contribution to the high local sea level elevation.In addition to the heat flux,the ENSO event also had a significant effect on the event,where the La Ni?a-induced northwest Pacific cyclone contributed to sea level rise over the northwestern SCS through dynamic and thermodynamic interactions.
