---|
| 43 | !! |
---|
| 44 | !! ** Purpose of the direct routine: |
---|
| 45 | !! Compute the bottom boundary contition on temperature |
---|
| 46 | !! associated with geothermal heating and add it to the general |
---|
| 47 | !! trend of temperature equations. |
---|
| 48 | !! |
---|
| 49 | !! ** Method : The geothermal heat flux set to its constant value of |
---|
| 50 | !! 86.4 mW/m2 (Stein and Stein 1992, Huang 1999). |
---|
| 51 | !! The temperature trend associated to this heat flux through the |
---|
| 52 | !! ocean bottom can be computed once and is added to the temperature |
---|
| 53 | !! trend juste above the bottom at each time step: |
---|
| 54 | !! ta = ta + Qsf / (rau0 rcp e3T) for k= mbathy -1 |
---|
| 55 | !! Where Qsf is the geothermal heat flux. |
---|

| 57 | !! ** Action : - update the temperature trends (ta) with the trend of |
