Table 2-12 Table 2-12: Planetary boundary layer (PBL). The table shows whether the PBL depth is a prognostic variable and whether the surface fluxes of momentum, heat, and moisture are stability-dependent. References are also listed on the scheme to determine vertical diffusion from turbulence kinetic energy (TKE), if present. Hyperlinks connect to the summary report for each AMIP model version.
