| 55 | !! ** Purpose : Compute the now total vorticity trend and add it to |
|---|
| 56 | !! the general trend of the momentum equation. |
|---|
| 57 | !! |
|---|
| 58 | !! ** Method : Trend evaluated using now fields (centered in time) |
|---|
| 59 | !! and the Sadourny (1975) flux form formulation : conserves the |
|---|
| 60 | !! horizontal kinetic energy. |
|---|
| 61 | !! The trend of the vorticity term is given by: |
|---|
| 62 | !! * s-coordinate (lk_sco=T), the e3. are inside the derivatives: |

|---|
| 65 | !! * z-coordinate (default key), e3t=e3u=e3v, the trend becomes: |
|---|
| 66 | !! voru = 1/e1u mj-1[ (rotn+f) mi(e1v vn) ] |
|---|
| 67 | !! vorv = 1/e2v mi-1[ (rotn+f) mj(e2u un) ] |
