%X Using the Simple Ocean Data Assimilation (SODA) climatological data, we compared the climatological oceanic stratification around the Antarctic and the Antarctic Circumpolar Current (ACC) region to conduct a preliminary study on the reasonable oceanic boundary condition of Antarctic ice sheet melting. Our results indicate freshwater flux induced by ice-melting will advect along the surface path in the East Atlantic and Indian Ocean, while in the West Atlantic and Pacific Ocean, the meridional motion path of freshwater flux depends on the intensity of freshwater flux itself. When there appears intense ice-melting of Antarctic, freshwater will travel along the surface path; when ice-melting is relatively generous, subsurface path will be preferred by freshwater flux. On the basis of these analyses, we quantitatively assessed the threshold state guaranteeing freshwater flux moving along surface path, and further analyzed the rationality of simulation of Antarctic ice-melting with idealized freshwater flux in most of current climate models, in order to providing neccessary reference for the selection of modeling strategy simulating the Antarctic ice-melting scenario.
