|
|
| 7 |
|
o Prather Advection scheme: fix tracer conservation for divergent flow |
| 8 |
|
(e.g., when using NonLin Free-Surface). |
| 9 |
|
o kpp: retire KPPmld diagnostics --> use MXLDEPTH instead |
| 10 |
|
o gmredi (Visbeck-variable-K): |
| 11 |
|
- add more parameters to Visbeck-variable-K. |
| 12 |
|
- use a 5 points average for dSigmaR in Visbeck-K calculation |
| 13 |
|
(more "homogenous": same stencil and same weights as in dSigmaH) |
| 14 |
|
- update output of ideal_2D_oce experiment. |
| 15 |
|
o fix CPP-flag REAL4_IS_SLOW, when _RS expands into real*4 |
| 16 |
|
(#undef REAL4_IS_SLOW) |
| 17 |
|
- pkg/mnc/mnc_cw_cvars.F: write _RS-grid variable as netcdf-real*4 |
| 18 |
|
coordinate variable |
| 19 |
|
- pkg/monitor/monitor.F: call mon_printstats_rs for _RS variables |
| 20 |
|
(surface forcing fields), removes some of the functionality |
| 21 |
|
- model/src/write_grid.F: write _RS variables as RS-netcdf variables |
| 22 |
|
- model/src/diags_oceanic_surf_flux.F: fix a few diagnostics, but |
| 23 |
|
probably not all: copy _RS surface flux fields to RL field before |
| 24 |
|
calling DIAGNOSTICS_FILL |
| 25 |
|
- model/inc/CPP_EEMACROS.h: make the _EXCH_*_RS macros expand into |
| 26 |
|
real*4 (CALL EXCH_*_RS) versions. |
| 27 |
|
- tested in 2 experiments: inverted_barometer & solid-body.cs-32x32x1 |
| 28 |
|
(generate new output). |
| 29 |
|
|
| 30 |
|
checkpoint61e |
| 31 |
|
o gmredi (Visbeck-variable-K): |
| 32 |
|
- fix the "OLD_VISBECK_CALC" option + move the #undef to GMREDI_OPTIONS.h |
| 33 |
|
- change computation of Visbeck-K where Slope > Smax : |
| 34 |
|
now: N*min(Slope,Smax) (similar to OLD_VISBECK_CALC with gkw91 taperFct) |
| 35 |
|
previously was: M*sqrt(min(Slope,Smax)) ; update ideal_2D_oce output. |
| 36 |
|
o bottom-drag in P-coord.: change units of bottomDragLinear & bottomDragQuadratic |
| 37 |
|
to be the same as with Z-coord. (i.e., m/s & no-units respectively). |
| 38 |
|
o calc_viscosity: fix index range (was wrong for CD-Scheme & explicit Visc) |
| 39 |
|
o pkg gmredi, linear & fm07 tapering: put an upper limit on Slope^2 so that Kwz |
| 40 |
|
does not become too large (to avoid precision problems in implicit-diffusion |
| 41 |
|
solver); update ideal_2D_oce output. |
| 42 |
|
o pkg ggl90: |
| 43 |
|
- in ggl90_cal.F: compute only one set of visc/diff, used to |
| 44 |
|
step forward TKE/T/S/momentum |
| 45 |
|
- default value of GGL90viscMax/GGL90diffMax larger and equal (to |
| 46 |
|
have Prandlt =1) |
| 47 |
|
o gmredi (fm07): |
| 48 |
|
- add lower limit on Transition layer thickness + lower limit on 1/lambda |
| 49 |
|
- allow to set few more params from data.gmredi |
| 50 |
|
o pkg ggl90: |
| 51 |
|
- add missing sqrt(2) factor in computation of mixing length |
| 52 |
|
scale in ggl90_calc.F |
| 53 |
|
(see Eq. (2.35) in Blanke and Delecluse, JPO, 1993) |
| 54 |
|
|
| 55 |
|
checkpoint61d |
| 56 |
|
o adjoint modifs |
| 57 |
|
- adapt to new field rhoInSitu |
| 58 |
|
- allow to revert from StoreDynVars2D, StoreDynVars3D |
| 59 |
|
to individual fields |
| 60 |
|
(switches AUTODIFF_USE_OLDSTORE_2D, AUTODIFF_USE_OLDSTORE_3D) |
| 61 |
|
o store 3-D (in-situ) density in commom block (DYNVARS.h) |
| 62 |
|
- save 1 rho computation. |
| 63 |
|
- no longer modify T & S inland when using down_slope pkg. |
| 64 |
|
o gad_som : allow to switch to SOM advection for T & S without corresponding |
| 65 |
|
pickup files (using new S/R: MDS_CHECK4FILE). |
| 66 |
|
o keep removing _BEGIN/_END_MASTER between MDSIO S/R call |
| 67 |
|
(for useSingleCpuIO to work in multi-threaded) |
| 68 |
|
o pkg/shelfice: |
| 69 |
|
- disentangle parameters: retire shelfIceFile in data/PARM05 and substitute |
| 70 |
|
with SHELFICEtopoFile in data.shelfice |
| 71 |
|
- move code for reading ice shelf topography and modifying hFacC into separate |
| 72 |
|
subroutines of the shelfice package |
| 73 |
|
- separate initialisation of "fixed" and "variable" variables |
| 74 |
|
- kTopC is not (yet) replaced by kSurfC, although this is possible |
| 75 |
|
o fix broken diagnostic SIatmFW and changed the units from m/s to kg/m^2/s |
| 76 |
|
o add initialisation of deepFac if using Pcoords (new S/R set_grid_factors) |
| 77 |
|
and rename: |
| 78 |
|
ini_phiref.F --> set_ref_state.F (+ set anelastic factors) |
| 79 |
|
ini_reference_state.F --> load_ref_files.F (- set anelastic factors) |
| 80 |
|
o change FIND_RHO_SCALAR : return rho (instead of rho - rhoConst) |
| 81 |
|
|
| 82 |
|
checkpoint61c |
| 83 |
|
o add option ALLOW_ADDFLUID and run-time selector "selectAddFluid" |
| 84 |
|
to add mass source/sink of fluid in the interior (3-D generalisation |
| 85 |
|
of oceanic real-fresh water flux). |
| 86 |
|
o pkg/monitor: fix recip_dr argument in mon_advcflw2 call (-> advcfl_W_hf_max) |
| 87 |
o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before) |
o vermix test experiment: switch from LINEAR EOS to MDJWF (not tested before) |
| 88 |
o new pkg: down_slope |
o new pkg: down_slope |
| 89 |
density-driven downsloping flow parameterisation (Tellus, 1999, 412-430). |
