Abstract: The temperature and salinity profiles of the Argo floats in the Warm Pool of the northwestern Pacific were analyzed. The results show that when typhoon passes, the sea surface salinity usually decreases in most observations, which is in contrast with that of the observations from the Atlantic Ocean when the SSS usually increases when hurricane passes. This is related to the typical thermal structure in this warm pool region and the difference between the precipitation processes associate with the typhoon in two oceans. The result is of importance to the study of the heat exchange processes and the mixing of the mixed-layer in the warm pool of the northwestern Pacific.
