1996; Xie and Carton 2004, e. g.) arises through the wind evaporation sea surface temperature (WES) feedback (Chang et al. 1997). Bjerknes associated the feedback loop of the oceanic and atmospheric circulation over the tropical Pacific as a "chain reaction", noting that "an intensifing Walker Circulation also provides for an increase of east-west temperature contrast that is the cause of the Walker Circulation in the first place." The Bjerknes feedback is a positive feedback between tropical Pacific surface wind and ocean temperature, which essentially means processes in the ocean and atmosphere goad each other to bring on an ENSO event.

The Bjerknes feedback in the normal state of the equatorial Pacific. Easterly trade winds produce eastern upwelling, fostering higher SST and convection in the  This coupled-ocean atmosphere interaction is known as the Bjerknes feedback, and remains the cornerstone of ENSO theory today. To understand the Bjerknes   14 Jan 2021 According to the Bjerknes-feedback loop, an initial SST anomaly in the eastern equatorial Atlantic alters the zonal SST gradient (dSST/dx),  somewhat irregular increase in both event frequency and amplitude throughout the Holocene, due to the Bjerknes feedback mechanism (Bjerknes, 1969) and  23 Oct 2020 The Bjerknes feedback is a positive feedback between tropical Pacific surface wind and ocean temperature, which essentially means  Key Points: 6.

2018-06-28 · In other words, Bjerknes feedback within the tropical Pacific alone cannot raise SST anomaly fast enough to counter seasonal SST cooling in the eastern Pacific and keep convective anomalies feedback leads the equatorial Pacific to a warm state, i.e., the warm phase of ENSO—El Niño. 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). After Bjerknes published his hypothesis, ENSO was not intensively studied until the 1980s.

When this feedback is particularly strong, and the SSTs in the eastern Pacific become significantly colder than their normally cool state, we have reached the cool phase of ENSO, known as La Niña conditions. Klaus Wyrtki, an oceanographer at the University of Hawaii, proposed an explanation.

Our knowledge of ENSO in the paleoclimate record has expanded rapidly within the last 5 years. The ENSO cycle is present in all relevant records, going back 130 kyr. The Bjerknes feedback and the resultant equatorial zonal mode of climate variability are a common feature to all three tropical oceans despite differences in dimension, geometry and mean climate.

“On interannual and longer timescales, no single mode seems to dominate.

The Bjerknes feedback processes include the equatorial zonal wind response to SST, the thermocline response to the equatorial zonal wind, and the ocean subsurface temperature response to the thermocline variation.
