| 摘 要： | 冰芯作为气候环境信息的良好载体,在研究过去大气环流异常中具有其他气候代用指标难以比拟的优势。本文重点综述了南极冰芯气候记录与南半球环状模(SAM-Southern Annular Mode)的关联特征:SAM与冰芯记录为同期变化,冰芯中NO-3、海盐组分(以Na+为代表)和水同位素比值δ18O同SAM指数具有较好的关联性;冰芯中SO2-4和MSA同SAM存在一定的关联,但相关性不显著;西南极冰芯记录的积累率同SAM具有较强的关联。需要说明的是,冰芯中各参数与SAM的相关性存在较大的空间差异。

| 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. |
