FV3: Finite-Volume Cubed-Sphere Dynamical Core
Idealized Tests
Shown here the idealized tests run for the NGGPS dycore evaluation and for DCMIP 2016. Additional idealized test results and notebooks for their analysis can be found on GitHub in the FV3 Examples directory.
Baroclinic wave test with embedded fronts (DCMIP test case 4.1)
Non-hydrostatic orographic mountain waves on a reduced-radius sphere (without rotation)
Case M1: Uniform flow over a ridge mountain. This is a modified version of DCMIP case 2.1 with a quasi-2D mountain ridge as described in the NCAR document http://hiwpp.noaa.gov/reports/NonhydrostaticDycoreIdealizedTestCasesReport.pdf mtn-new.pdf , equation 12) with a ridge height of 250m. The model top is positioned at 20km (instead of 30 km) with an absorbing layer above 10-km, a horizontal resolution of 1.1 degrees (~720 meters) and a vertical grid spacing of approximately 500 meters. Sphere radius reduction factor 166.7.
Case M2: Uniform flow over a circular mountain. This case follows DCMIP case 2.1 (no vertical shear with a Schär-type circular mountain). Horizontal grid spacing 0.55 degrees (~360 meters). Vertical grid spacing approximately 250 meters. Other parameters as in Table XIII of DCMIP test document, except X=166.67 instead of 500.
