To further investigate whether there is a difference in the effect of multi-year intergenerational variability of SST (AMV_Trop and AMV_SPG) on SASM between the tropical and mid- to high-latitude North Atlantic, this paper is based on the large ensemble dataset of the Center for Earth System Modeling (CESM) (CESM-LE) Pre-Industrial Revolutionary Reference Experiment (PiControl) of 1800 and the 1920~2005 42 The CESM large ensemble dataset (CESM-LE) 1800 pre-Industrial Revolution Reference Experiment (PiControl) and the Historical Experiment (Historical) dataset from 1920 to 2005 of 42 members of the PiControl group were used to evaluate the model-simulated AMVs and SASMs in different regions by comparing them with the observations and reanalyses as well as to compare and analyze the linkages between AMVs and SASMs in different regions. The results show that: 1) CESM model can simulate the main spatial and temporal characteristics of AMV in tropical and subpolar regions, as well as the basic characteristics of precipitation and atmospheric circulation in SASM region. 2) In the observations, the positive-phase AMV in different regions corresponds to an increase in precipitation and decrease in temperature in the central region of South Asia, and a decrease in precipitation and increase in temperature in the northern region. 3) In the pre-industrial revolution reference experiments, AMV and AMV_SPG in ortho-phase corresponded to an increase in precipitation in the southern end of the South Asian region and a non-significant decrease in precipitation in the northern region, and the temperature change was warm in the ortho-phase of AMV and exhibits large cold-biased anomalies in AMV_SPG;the ortho-phase AMV_Trop corresponded to a decrease in precipitation and an increase in temperature in the South Asian region. 4) The average results of the 42 sets of historical experiments are contrary to the observations, and the ortho-phase AMV in different regions corresponds to a decrease in precipitation in South Asia. However, 30 of the 42 sets of experiments show variations consistent with observations, and 12 sets show opposite variations. This suggests instability in the linkage between AMV and SASM.展开更多
