Which feedback results from depleted upwelling during El Niño?

💡 Explanation

Increased atmospheric temperatures persist because the diminished upwelling reduces the transfer of cold, nutrient-rich water, initiating a positive feedback via reduced cooling (Bjerknes feedback). Therefore, temperature increases persist rather than being regulated quickly by ocean cooling alone.
