Evolution of the South Atlantic Anomaly (SAA) over the period 1970–2070 calculated from the ensemble assimilation (note that after 2020 only the forecast is shown, while before only the analyses are displayed). The background contour lines represent the field intensity based on the mean analysis in 2020 and the symbols correspond to the position and intensity (color scale) of the two minima every 10 years. The error bars correspond to the 1\(\sigma\) uncertainty in latitude and longitude, while the symbol size scales with the uncertainty in the intensity of each minimum point in time
