Five level intermediate atmospheric physics example. |
2 |
Experimental configuration is an equatorial channel |
3 |
of 65 degrees wide cented on the Equator. A warm SST anomaly |
4 |
with a gaussian shape is defined at the center of the domain |
5 |
with an extension of ~30 degrees meridionally and ~60 degrees |
6 |
zonally. |
7 |
|
8 |
The local copy of S/R aim_surf_bc.F (in code directory) provide |
9 |
a) the SST field (hard coded). |
10 |
b) the time in the year is fixed and corresponds to the spring equinox; |
11 |
this ensures a symetric forcing between N & S hemispheres. |
12 |
The model uses the standard 5-level vertical resolution of the Speedy_v23 |
13 |
code; the horizontal resolution is 2.8125 with 128x23 grid points. |

o To reproduce the run : |
18 |
|
19 |
The genmake options are in .genmakerc, so that the simplest form |
20 |
of genmake can be used : |
21 |
cd build |
22 |
../../../tools/genmake2 -mods=../code [-of= ... if needed] |
23 |
make depend |
24 |
make |
25 |
|
26 |
ln -s ../input/* . |

Notes: |
31 |
* To produce a short test that is relevant for the Atmosphere physics part, |
32 |
a restart file (pickup.0000051840) is included. The model reaches |
33 |
a statistical equilibrium after 1 year. |
34 |
* the file aim_SST.* contains the SST field. |
35 |
* Since aim pkg uses arrays with MAX_NO_THREADS as dimension, the maximum |
36 |
number of treads is set to 1 (in code/EEPARAMS.h) instead of 32, so that the |
37 |
size of the executable is reduced. This obviously needs to be changed |
38 |
before compiling on a multi-threaded platform. |

Northern boundary : |
41 |
o initially, the domain (SIZE.h) 128x24x5 with a land line as the Northern |
42 |
boundary, reduciong the effective domain to 128x23x5. |
43 |
o To have a more efficient code (and a good starting point for MIT Atmos. |
44 |
Physics), the new domain (SIZE.h) is now 128x23x5 . |
45 |
Northern and Southern boundaries are "closed" like the in Lat-Lon set-up. |
