Why choose to run the model without a convective parameterization?
We find that this model performs at least as well as, and possibly better than, a version with one particular parameterization scheme that we have worked with in the past, and it is certainly a simpler model without using this complex closure scheme. The choice of running without a convection scheme was thus an application of “Occam’s razor”, based on this limited set of simulations. We have not been able to compare the quality of our simulations using a larger set of alternative convective parameterizations, because of the computational expense of this model. Running without a convection parameterization scheme is admittedly unconventional at this resolution.
