Abstract: Ice cores contain a wealth of information on climate and have many advantages over other climate proxies in the study of past atmospheric circulation. Here, we summarized the relationship between the Southern Annular Mode (SAM) and Antarctic ice core records. The SAM varied simultaneously with ice core proxies, and NO3, sea salt ions (mainly Na+), and water isotopes (δ18O) correlated well with the SAM index (SAMI). However, there was no significant correlation between SO42− and methanesulfonate levels and SAMI. The accumulation rate (acc) recorded in a West Antarctic ice core implied that acc was positively correlated with SAMI. However, the relationship between ice core parameters and SAMI showed marked spatial variation.
