X ray microbursts in the South Atlantic magnetic anomaly
Journal of Geophysical Research: Space Physics, 1996 Balloon‐borne X ray measurements with high time resolution were carried out in the South Atlantic magnetic anomaly to investigate the fine structure of the precipitation in this region. Measurements were obtained on two balloon flights launched from Cachoeira Paulista, São Paulo, Brazil, on January 26 and February 1, 1994, and were supported by onboard

Auroral Asymmetry Associated With the South Atlantic Anomaly
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,

Decline in Atlantic Niño prediction skill in the North American multi-model ensemble
Communications Earth & EnvironmentThe Atlantic Niño has attracted considerable attention due to its profound climatic impacts. It has been reported that the strength of Atlantic Niño has been weakening since 2000, but it is not clear whether it would lead to a change in Atlantic Niño ...

Ascension and Port Stanley geomagnetic observatories and monitoring the South Atlantic Anomaly
Annals of Geophysics, 2009 Our 15-year experience of operating two remote observatories, Ascension and Port Stanley, in the south Atlantic<br />is described. These observatories help monitor the South Atlantic Anomaly (SAA), a region of weak magnetic<br />field which ...

South Atlantic island record reveals a South Atlantic response to the 8.2 kyr event [PDF]
Climate of the Past, 2008 One of the most distinct climate fluctuations during the Holocene is the short and rapid event centred around 8200 years ago, the 8.2 kyr event, which was most likely triggered by glacial melt-water forcing from the receding Laurentide ice-sheet ...

Geomagnetic observations on Tristan da Cunha, South Atlantic Ocean
Annals of Geophysics, 2009 Few geomagnetic ground observations exist of the Earth’s strongest core field anomaly, the South Atlantic Anomaly<br />(SAA). The geomagnetic repeat station on the island Tristan da Cunha, located half-way between South Africa<br />and South ...

Long-term persistency of a strong non-dipole field in the South Atlantic
Nature CommunicationsEarth’s magnetic field exhibits a dominant dipole morphology. Notwithstanding, significant deviations from the dipole are evident today, particularly the South Atlantic Anomaly (SAA), characterized by anomalously low-field intensity and high directional ...
