2000; Keenlyside and Latif 2007; Janssen et al. 2008), whereas the meridional mode on decadal time scales (Zebiak 1993; Carton et al. 1996; Xie and Carton 2004, e. g.) arises through the wind evaporation sea surface temperature (WES) feedback (Chang et al. 1997). This mechanism, which is known as Bjerknes Feedback, is similar to El Niño/Southern Oscillation (ENSO).

During the Atlantic Nino event, eastern area of Atlantic will appear warm SST anomalies accompanying a relaxation of trade winds. This mechanism, which is known as Bjerknes Feedback, is similar to El Niño /Southern Oscillation (ENSO). “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. Bjerknes’ positive feedback, the oscillatory nature of ENSO needs a negative feedback to turn the coupled ocean-atmosphere system from a warm (cold) phase to a cold (warm) phase.

Van der Swaluw et al ., 2007).

The trade winds normally pile up warm surface water in the western Pacific while upwelling colder water in the east from below the sur-face along the equator and off the west coast of South America.

To examine the seasonality, symmetry, and stationarity of the Pacific and Atlantic Bjerknes feedbacks we decompose them into three feedback elements that relate thermocline depth, sea surface temperature (SST), and western basin wind stress variability to each other. Bjerknes hypothesized that a positive ocean–atmosphere feedback process causes ENSO. Given an initial warm sea-surface temperature (SST) anomaly in the equatorial eastern Pacific, the warm SST anomaly reduces the east–west SST gradient and hence weakens the Walker circulation [ 2 , 3 ], producing the westerly wind anomaly in the equatorial central Pacific.
