Destabilization of the Thermohaline Circulation by Atmospheric Eddy Transports

摘要: Abstract Simple proem models have been developed to investigate the role of atmosphere-ocean feedbacks in stability current mode thermohaline circulation North Atlantic. A positive feedback between meridional atmospheric transport moisture and high-latitude sinking (EMT feedback) has found help destabilize latter. The minimum perturbation required shut off is considerably smaller when this included. Also, much faster with than without it, given a same magnitude. There also strong heat circulation, but can be modeled accurately on global scale by using properly tuned Newtonian cooling law for surface beat flux. Idealized flux adjustment experiments suggest that sensitivity real climate not represented well coupled atmos...
