Bjerknes feedback

This study investigates the • Extreme El Nino decays slowly because of local Bjerkness feedback in the eastern Pacific, by causing deep convection there. • Extreme coastal El Nino of March 2017 was preceded by a weak basin-scale La Nina, triggered by intraseasonal westerlies and amplified by coastal Bjerknes feedback. Conclusions Corresponding to the pronounced amplitude asymmetry for the central Pacific (CP) and eastern Pacific (EP) types of El Niño, an asymmetry in the strength of the Bjerknes positive feedback is found between these two types of El Niño, which is manifested as a weaker relationship between the zonal wind anomaly and the zonal gradient of sea surface temperature (SST) anomaly in the CP El Niño. The Bjerknes feedback is the dominant coupled, positive feedback in the equatorial oceans (Bjerknes, 1966, 1969). It plays a crucial role in shaping Atlantic and Pacific equatorial variability, tying three key properties of an equatorial ocean basin into a closed feedback loop.

Other studies ( 12 , 14 , 25 ) consistently suggest that the El Niño–like response following NH tropical eruptions may be initiated by a southward displacement of the ITCZ, while Southern Hemisphere (SH) volcanic eruptions may then The Bjerknes Feedback (BF) intensity, which dominates the development of ENSO, has been proposed to determine ENSO predictability. Here we demonstrate that decada Equatorial wave-induced cooling thus represents a delayed negative feedback that brings about the demise of El Niño and, if strong enough, the initiation of La Niña. The combination of Bjerknes and equatorial wave feedbacks controls the magnitude and duration of individual ENSO events and the interval between them. 2019-08-12 · This Bjerknes feedback continues to amplify and enhance initial SST perturbations into a large-scale warming in the tropical eastern Pacific—an El Niño event. In addition to the Bjerknes feedback, other ocean–atmosphere feedback processes were also proposed and hypothesized after the 1990s.

stronger SST gradients --> stronger winds --> stronger SST gradients), whereas “negative” feedbacks will act to dampen/counteract the initial change. Consequently, the Walker circulation is associated with a positive feedback, called the Bjerknes feedback (Fig. 5.3), in which the easterly surface wind stress enhances the zonal SST gradient which in turns amplifies the wind stress.

During Bjerknes’ pioneer-ing studies, the causes of a turnabout from a warm phase to a cold phase (La Niña) was not known (Philander 1990).
