2 The purpose of this case is to demonstrate an idealized convective-radiative
3 equilibrium 3d run driven by the SST. Run for weeks to months, this develops
4 a steady-state convection in a weak wind background typical of the tropics
5 with a grid size small enough (1 km) to resolve individual updrafts.
6 The test case domain and run length are small compared to typical runs and
7 serve only as a demonstration.
9 The initialization makes use of the full physics initialization in the
10 sea-breeze case but, new in V3.7, the SST can be specified in input_sounding
11 via the surface temperature in the first line and the surface is all-ocean
12 by default. There is a small Coriolis force of 2.5e-5 and a random low-level
13 temperature perturbation to initiate the convection.
15 The input sounding has u=5 m/s, and SST=300 K with a moist profile to support
17 pert_coriolis is true so the input_sounding wind is taken to be geostrophically
19 Use the run_me_first.csh script to copy necessary data files for radiation.
21 This setup is for a 3D case with 101x101 grid points, dx=1 km, and 35 eta levels.
22 The top is at 30 km. The physics choices are WSM6 microphysics, RRTMG radiation,
23 the 5-layer slab model (inactive due to water surface), and YSU PBL scheme.
24 There are periodic boundaries and w-Rayleigh damping at the top.
25 Buckets are turned on for rainfall and radiation budgets because this is designed
26 to be a long run that may be a month or more to obtain equilibrium.
