Auroral Asymmetry Associated With the South Atlantic Anomaly [PDF]
Geophysical Research LettersAbstract The South Atlantic anomaly (SAA) exerts a weakening effect on magnetic field strength on Earth, however, little is known of its effect on the auroral spatial distribution and temporal evolution. Using Defense Meteorological Satellite Program/Special Sensor Ultraviolet Spectrographic Imager ultraviolet data spanning 2016–2023,

The South Atlantic Anomaly throughout the solar cycle [PDF]
Earth and Planetary Science Letters, 2017 Abstract The Sun–Earth's interaction is characterized by a highly dynamic electromagnetic environment, in which the magnetic field produced in the Earth's core plays an important role. One of the striking characteristics of the present geomagnetic field is denoted the South Atlantic Anomaly (SAA) where the total field intensity is unusually low and ...

The South Atlantic Anomaly: the key for a possible geomagnetic reversal
Frontiers in Earth Science, 2016 The South Atlantic Anomaly is nowadays one of the most important features of the Earth’s magnetic field. Its extent area at the Earth’s surface is continuously growing since the intensity instrumental measurements are available covering part of the ...

Relating the South Atlantic Anomaly and geomagnetic flux patches
Physics of the Earth and Planetary Interiors, 2017 Abstract The South Atlantic Anomaly (SAA) is a region of weak geomagnetic field intensity at the Earth’s surface, which is commonly attributed to reversed flux patches (RFPs) on the core-mantle boundary (CMB). While the SAA is clearly affected by the reversed flux region below the South Atlantic, we show that the relation between the intensity ...

Mapping the South Atlantic Anomaly continuously over 27 years
Journal of Atmospheric and Solar-Terrestrial Physics, 2018 Abstract The South Atlantic Anomaly (SAA) is a region of reduced magnetic intensity where the inner radiation belt makes its closest approach to the Earth's surface. Satellites in low-Earth orbit pass though the SAA periodically, exposing them to several minutes of strong radiation each time, creating problems for scientific instruments, human safety,

South Atlantic Surface Boundary Current System during the Last Millennium in the CESM-LME: The Medieval Climate Anomaly and Little Ice Age [PDF]
Geosciences, 2019 Interocean waters that are carried northward through South Atlantic surface boundary currents get meridionally split between two large-scale systems when meeting the South American coast at the western subtropical portion of the basin.
