ES3M fig3 | E3SM-MMF Addresses a Significant Source of Uncertainty in Climate Projection Models with Exascale Capable Software

Figure 3. In E3SM-MMF, a 2D CRM represents cloud-scale processes within each cell of a 3D global atmospheric model. The CRM does not fill the entire parent cell of global grid, and thus represents a sample of how the convective-scale processes are responding to the large-scale conditions. The two models are tightly coupled through the exchange of heat and moisture tendencies such that their internal states remain consistent. The figure shown above depicts the approximate size and orientation of the CRM instances (rectangles standing on edge) inside each cell of the global grid from a recent E3SM-MMF simulation. Color shading shows a snapshot of precipitation on the surface of the global grid and the corresponding cloud condensate fields within the CRM instances.
