Abstract: The temperature and salinity profiles of the Argo floats in the Warm Pool of Northwestern Pacific were analyzed. The results show that when Typhoon passes, the Sea Surface Salinity (SSS) usually decreases in most observations, which is in contrast with that of the observations from Atlantic Ocean where the SSS usually increases when Hurricane passes. This is related with the typical thermal structure in this warm pool region and the differences between the precipitation processes associated with the typhoon in the two ocean. The result of this work is of importance for the study of the heat exchange processes and the mixing of the mixed-layer in the Warm Pool of Northwestern Pacific.
Key words: Argo floats; typhoon; mixed layer; sea surface salinity
