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.

The Storm-Track Response to Idealized SST Perturbations in an Aquaplanet GCM [PDF]

, 2008
The tropospheric response to midlatitude SST anomalies has been investigated through a series of aquaplanet simulations using a high-resolution version of the Hadley Centre atmosphere model (HadAM3) under perpetual equinox conditions.

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 ...

The radiation environment in a Low Earth Orbit: the case of BeppoSAX

, 2014
Low-inclination, low altitude Earth orbits (LEO) are of increasing importance for astrophysical satellites, due to their low background environment. Here, the South Atlantic Anomaly (SAA) is the region with the highest amount of radiation.

GEOID ANOMALIES OVER 2 SOUTH-ATLANTIC FRACTURE-ZONES

, 2016
Seasat altimetry profiles across the Falkland-Agulhas fracture zone (FZ) and the Ascension FZ in the South Atlantic were examined for evidence of step-like geoid offsets predicted from thermal modeling of the lithosphere. The geoid profiles exhibit much short-wavelength power and the step-like offsets are often small, making reliable estimation of the ...

Decline in Atlantic Niño prediction skill in the North American multi-model ensemble

Communications Earth & Environment
The 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 ...

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 ...

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 ...

Multiple causes of interannual sea surface temperature variability in the equatorial Atlantic Ocean [PDF]

, 2012
The eastern equatorial Atlantic Ocean is subject to interannual fluctuations of sea surface temperatures, with climatic impacts on the surrounding continents.
