摘要	Ocean biology components affect the vertical redistribution of incoming solar radiation in the upper ocean of the tropical Pacific and can significantly modulate El Nino-Southern Oscillation (ENSO). The biophysical interactions in the region were represented by coupling an ocean biology model with an ocean general circulation model (OGCM); the coupled ocean physics-biology model is then forced by prescribed wind anomalies during 1980-2007. Two ocean-only experiments were performed with different representations of chlorophyll (Chl). In an interannual Chl run (referred to as Chl(inter)), Chl was interannually varying, which was interactively calculated from the ocean biology model to explicitly represent its heating feedback on ocean thermodynamics. The structure and relationship of the related heating terms were examined to understand the Chl-induced feedback effects and the processes involved. The portion of solar radiation penetrating the bottom of the mixed layer (Q(pen)) was significantly affected by interannual Chl anomalies in the western-central equatorial Pacific. In a climatological run (Chl(clim)), the Chl concentration was prescribed to be its seasonally varying climatology derived from the Chl(inter) run. Compared with the Chl(clim) run, interannual variability in the Chl(inter) run tended to be reduced. The sea surface temperature (SST) differences between the two runs exhibited an asymmetric bioeffect: they were stronger during La Nina events but relatively weaker during El Nino events. The signs of the SST differences between the two runs indicated a close relationship with Chl: a cooling effect was associated with a low Chl concentration during El Nino events, and a strong warming effect was associated with a high Chl concentration during La Nina events.
