Where can I find a description of the ocean model used by EdGCMs “Predicted SST (QFlux)” technique?
The simple ocean model used for the predicted sea surface temperature (SST) simulations in the GISS GCM is called a mixed-layer ocean model, because it simulates only the upper portion of the ocean that is well mixed with respect to temperature and salinity. Mixed-layer ocean models allow the GCM to account for the heat capacity of a large volume of water. For modern runs, the mixed layer thickness is dependent upon geographic location and season. Such data are not available for paleoclimate simulations, which use a constant 250-meter-deep mixed layer. By using the mixed-layer ocean model, SSTs can adjust to changes in the climate forcings, thus allowing for a two-way feedback between atmosphere and oceans. The GISS mixed-layer ocean model employs a “Qflux technique” which explicitly alters heat in each grid cell to mimic horizontal ocean heat transports (ocean currents). The Qflux technique is described more fully in several publications: • Miller, J.R., Russell, G.L., and Tsang, L.-C
