SAM INDICES IN THE LAST MILLENIUM

Figure number: Figure 3.35 From the IPCC Working Group I Contribution to the Sixth Assessment Report: Chapter 3

Description:

Southern Annular Mode (SAM) indices in the last millennium. (a) Annual SAM reconstructions by Abram et al. (2014) and Dätwyler et al. (2018). (b) The annual-mean SAM index defined by Gong and Wang (1999) in CMIP5 and CMIP6 Last Millennium simulations extended by historical simulations. All indices are normalized with respect to 1961-1990 means and standard deviations. Thin lines and thick lines show 7-year and 70-year moving averages, respectively.
