C *==========================================================* |

C | SUBROUTINE LONGSTEP_THERMODYNAMICS |
| 19 |
C | o Controlling routine for the prognostics of passive tracers |
| 20 |
C | with longer time step. |
| 21 |
C *=========================================================== |
| 22 |
C | This is a copy of THERMODYNAMICS, but only with the |
| 23 |
C | parts relevant to ptracers, and dynamics fields replaced |
| 24 |
C | by their longstep averages. |
| 25 |
C | When THERMODYNAMICS is changed, this routine probably has |
| 26 |
C | to be changed too :( |
