|---|
| 184 | !! *** ROUTINE trd_mld *** |
|---|
| 185 | !! |
|---|
| 186 | !! ** Purpose : Compute and cumulate the mixed layer trends over an analysis |
|---|
| 187 | !! period, and write NetCDF (or dimg) outputs. |
|---|
| 188 | !! |
|---|
| 189 | !! ** Method/usage : |
|---|
| 190 | !! The stored trends can be chosen twofold (according to the ln_trdmld_instant |
|---|
| 191 | !! logical namelist variable) : |
|---|
| 192 | !! 1) to explain the difference between initial and final |
|---|
| 193 | !! mixed-layer T & S (where initial and final relate to the |
|---|
| 194 | !! current analysis window, defined by ntrd in the namelist) |
|---|
| 195 | !! 2) to explain the difference between the current and previous |
|---|
| 196 | !! TIME-AVERAGED mixed-layer T & S (where time-averaging is |
|---|
| 197 | !! performed over each analysis window). |
|---|
| 198 | !! |
|---|
| 199 | !! ** Consistency check : |
|---|
| 200 | !! If the control surface is fixed ( nctls > 1 ), the residual term (dh/dt |
|---|
| 201 | !! entrainment) should be zero, at machine accuracy. Note that in the case |
|---|
| 202 | !! of time-averaged mixed-layer fields, this residual WILL NOT BE ZERO |
|---|
| 203 | !! over the first two analysis windows (except if restart). |
|---|
| 204 | !! N.B. For ORCA2_LIM, use e.g. ntrd=5, ucf=1., nctls=8 |
|---|
| 205 | !! for checking residuals. |
|---|
| 206 | !! On a NEC-SX5 computer, this typically leads to: |
|---|
| 207 | !! O(1.e-20) temp. residuals (tml_res) when ln_trdmld_instant=.false. |
|---|
| 208 | !! O(1.e-21) temp. residuals (tml_res) when ln_trdmld_instant=.true. |
|---|
| 209 | !! |
|---|
| 210 | !! ** Action : |
|---|
| 211 | !! At each time step, mixed-layer averaged trends are stored in the |
|---|
| 212 | !! tmltrd(:,:,jpmld_xxx) array (see trdmld_oce.F90 for definitions of jpmld_xxx). |
|---|
| 213 | !! This array is known when trd_mld is called, at the end of the stp subroutine, |
|---|
| 214 | !! except for the purely vertical K_z diffusion term, which is embedded in the |
|---|
| 215 | !! lateral diffusion trend. |
|---|
| 216 | !! |
|---|
| 217 | !! In I), this K_z term is diagnosed and stored, thus its contribution is removed |
|---|
| 218 | !! from the lateral diffusion trend. |
|---|
| 219 | !! In II), the instantaneous mixed-layer T & S are computed, and misc. cumulative |
|---|
| 220 | !! arrays are updated. |
|---|
| 221 | !! In III), called only once per analysis window, we compute the total trends, |
|---|
| 222 | !! along with the residuals and the Asselin correction terms. |
|---|
| 223 | !! In IV), the appropriate trends are written in the trends NetCDF file. |
