A reexamination of the polar halocline catastrophe and implications for coupled ocean-atmosphere modeling

In this paper, the physical mechanism of the polar halocline catastrophe (PHC) is reexamined with emphasis on the role played by the surface heat flux. It is argued that, in a coupled ocean-atmosphere system, thermal changes in the atmospheric state in response to changes in heat flux from the ocean...

Zusammenfassung:In this paper, the physical mechanism of the polar halocline catastrophe (PHC) is reexamined with emphasis on the role played by the surface heat flux. It is argued that, in a coupled ocean-atmosphere system, thermal changes in the atmospheric state in response to changes in heat flux from the ocean weaken the feedback responsible for the PHC.
