ENSO events are major source of interannual variability in atmospheric CO 2 growth rate due to their effect on fluxes through land and on surface ocean temperature and precipitation.
NAO consists of opposing variations of surface atmospheric pressure near Iceland and near the Azores. It corresponds to fluctuations in the strength of the main westerly winds across the Atlantic into Europe, and thus to fluctuations in the associated cyclones with their frontal systems. SAM is an interannual to centennial climatic variability that influences zonal i.
During the initial positive phase, SAM is associated with enhanced westerly winds over the Antarctic Circumpolar Current, which flows around Antarctica. This favors the strengthening of the current and the northward expansion of sea ice. To compensate there is enhanced pole-ward transport and rising of deep waters at Antarctic continental margin. During the opposite negative phase a weakening of both zonal and meridional i.
