Variability, changes and impacts of the Southern Annular Mode across timescales
Abstract
Variability, changes and impacts of the Southern Annular Mode across timescalesWe identify an opportunity to review the literature on the leading mode of Southern Hemisphere extratropical variability, which we denote as the Southern Annular Mode (SAM) but including both zonal and meridional circulation. The SAM impacts surface climate across the Southern Hemisphere, influencing surface temperature and precipitation means and extremes as well as sea ice coverage and ocean circulation. Our review will synthesize the literature on the SAM across timescales from weeks to decades with a focus on describing our mechanistic understanding of key processes. Wepropose to hold a workshop to present and discuss the advances and knowledge gaps in our understanding of the variability, predictability, trends and impact of the SAM across timescales. This workshop will facilitate the preparation of a review manuscript for submission to Nature Reviews Earth & Environment (impact factor 13.3), to enhance the conversation of SAM and its impacts across the research community.
