2004), Variability of the Antarctic circumpolar transport and the Southern Annular Mode associated with the Madden‐Julian Oscillation, Geophys. Res
[1] The variability of oceanic Antarctic circumpolar transport and the atmospheric Southern Annular Mode (SAM) on intraseasonal (30–70-day) timescales is shown to be related to the tropical atmospheric Madden-Julian Oscillation (MJO) during southern winter. Approximately 7 days after anomalous MJO c...
