Bjerknes feedback is the positive coupled ocean-atmosphere feedback loop in which the east-west (Walker circulation) trade winds, driven by rotation-dependent pressure/temperature gradients, maintain the warm-west/cool-east SST asymmetry across the tropical Pacific via wind-driven thermocline tilt and upwelling.
The Bjerknes feedback loop depends on trade winds (driven partly by the Coriolis-influenced pressure gradient) piling up warm water in the west and enhancing upwelling...
