C |ocean bathymetry: |

|
|
C | The depths of the bottom of the model is specified in |
19 |
|
|
C | terms of an XY map with one depth for each column of |
20 |
|
|
C | grid cells. Depths do not have to coincide with the |
21 |
|
|
C | model levels. The model lopping algorithm makes it |
22 |
|
|
C | possible to represent arbitrary depths. |
23 |
|
|
C | The mode depths map also influences the models topology |
24 |
|
|
C | By default the model domain wraps around in X and Y. |
25 |
|
|
C | This default doubly periodic topology is "supressed" |
26 |
