C | Currently AIM exports to the dynmaics | |

|
C | - PBL drag coefficient | |
| 15 |
|
|
C | - Net tendency for temperature | |
| 16 |
|
|
C | - Net tendency for water vapor | |
| 17 |
|
|
C | Exporting drag has the nice property that it is a scalar.| |
| 18 |
|
|
C | This means that the exchanges on the AIM exported fields | |
| 19 |
|
|
C | do not need special piaring on the cube. It may not be | |
| 20 |
|
|
C | a good idea in the long term as it makes assumptions | |

|
|
C | about the momentum schemes within AIM. | |
