# FV3: Finite-Volume Cubed-Sphere Dynamical Core

## Idealized Tests

### 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 SchÃ¤r-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.
