RISA Comparative Stability Analysis of Atlantic and Pacific Niño Modes
Publisher: American Meteorological Society
Abstract: l Niño?Southern Oscillation (ENSO) in the Pacific and the analogous Atlantic Niño mode are generated by processes involving coupled ocean?atmosphere interactions known as the Bjerknes feedback. It has been argued that the ...
Assessing the Twenty-First-Century Shift in ENSO Variability in Terms of the Bjerknes Stability Index
Publisher: American Meteorological Society
Abstract: decadal change in the character of ENSO was observed around year 2000 toward weaker-amplitude, higher-frequency events with an increased occurrence of central Pacific El Niños. Here these changes are assessed in terms of ...
On the Inconsistent Relationship between Pacific and Atlantic Niños
Publisher: American Meteorological Society
Abstract: he tropical Atlantic wind response to El Niño forcing is robust, with weakened northeast trade winds north of the equator and strengthened southeast trade winds along and south of the equator. However, the relationship ...
Contribution of Increased Agulhas Leakage to Tropical Atlantic Warming
Publisher: American Meteorological Society
Abstract: he upper tropical Atlantic Ocean has markedly warmed since the 1960s. It has been shown that this warming was not due to local heat fluxes and that the trade winds that drive the coastal and equatorial upwelling have ...
Variability in the South Atlantic Anticyclone and the Atlantic Niño Mode
Publisher: American Meteorological Society
Abstract: revious studies have argued that the strength of the South Atlantic subtropical high pressure system, referred to as the South Atlantic anticyclone (SAA), modulates sea surface temperature (SST) anomalies in the eastern ...
