Equatorial electrojet in the south Atlantic anomaly region

Journal of Earth System Science, 2011
Features of the equatorial electrojet are studied at Sao Luiz (2.6°S, 44.2°W, inclination −0.25°) in eastern Brazil and Sikasso (11.3°N, 5.7°W, inclination 0.1°) in the western African sector. The stations are situated on either side of the lowest magnetic field intensity in the region of rapid changes in the declination.

Ever‐present South Atlantic Anomaly damages spacecraft [PDF]

Eos, Transactions American Geophysical Union, 2002
On 15 June 2001, at 3:56 UT, the Moderate Resolution Imaging Spectroradiometer (MODIS), one of NASAs prime remote sensing instruments on the TERRA spacecraft, was rendered inoperative while on the western flank of the South Atlantic Anomaly (SAA). The SAA is a vaguely‐defined, oval‐shaped geographic region centered roughly off the east coast of Brazil ...

Magnetic core field anomalies in the non-axial field during the last 3300 years: approach with an equivalent monopole source

Frontiers in Earth Science
The continuous update of the archeomagnetic database spanning the last 3,000 years has facilitated the refinement of geomagnetic field models, unveiling the presence of significant non-dipolar anomalies before instrumental measurements.

On the Decadal Changes of the Interannual Relationship Between ENSO and Tropical South Atlantic SST in Boreal Summer

Geophysical Research Letters, 2023
This study aims to investigate the underlying mechanisms driving changes in the contemporaneous relationship between El Niño–Southern Oscillation (ENSO) and tropical South Atlantic (TSA) sea surface temperatures (SST) during boreal summer over the past ...

Influences of Central and Eastern Atlantic Niño on the West African and South American summer monsoons

npj Climate and Atmospheric Science
The rainfall variabilities of the West African and South American summer monsoons, pivotal for local and global climate systems, are strongly influenced by tropical Atlantic sea surface temperature anomalies.

Medidas de Campos Elétricos com Detetores a Bordo de Balões Estratosféricos na Região da Anomalia Magnética do Atlântico Sul

Brazilian Journal of Geophysics, 1985
ln this work new measured values for the atmospheric electric fields in the region of the South Atlantic Magnetic Anomaly are presented. The data were obtained in 1981 using a stratospheric balloon-borne double probe detector.

Modelling global-scale climate impacts of the late Miocene Messinian Salinity Crisis [PDF]

Climate of the Past, 2014
Late Miocene tectonic changes in Mediterranean–Atlantic connectivity and climatic changes caused Mediterranean salinity to fluctuate dramatically, including a ten-fold increase and near-freshening.
