| 34 |
|
|
C ------------- |
| 35 |
|
|
C |
| 36 |
|
|
C * this version (1.0) of the physics package is intended to be used over |
| 37 |
|
|
C a tropical aqua-planet (no sea ice, no distinction between land and |
| 38 |
|
|
C ocean surfaces, no specific cloudiness associated with mid-latitude |
| 39 |
|
|
C weather systems, etc.) |
| 40 |
|
|
C ... but nothing precludes to complete it later on ! |
| 41 |
|
|
C |
| 42 |
|
|
C * for a non-equatorial version of the model, don't forget to specify |
| 43 |
|
|
C the latitude (RLAT) seen by radiation. |
| 44 |
|
|
C |
| 45 |
|
|
C * if you change the vertical resolution, change it accordingly |
| 46 |
|
|
C in the file ../inc/dimensions.h (this is for the radiation code) |
| 47 |
|
|
C and also in convect43b.F (NLEV=...) |
| 48 |
|
|
C (not very satisfying...will have to be improved) |

| 52 |
|
|
C ------------------------------------------------------------- |
| 53 |
|
|
C |
| 54 |
|
|
C - opposite convention used for numbering the vertical levels |
| 55 |
|
|
C (here, the 1st atmospheric level is the nearest to the surface) |
| 56 |
|
|
C |
| 57 |
|
|
C - QG1 (specific humidity) is in kg/kg |
| 58 |
|
|
C |
| 59 |
|
|
C - all the physics package is called atmospheric column by |
| 60 |
|
|
C atmospheric column (note that the radiation code would |
| 61 |
|
|
C easily accept to work with 3D fields) |
