|---|
| 64 | !! ** Purpose : Compute the before horizontal tracer (t & s) diffusive |
|---|
| 65 | !! trend for a laplacian tensor (ezxcept the dz[ dz[.] ] term) and |
|---|
| 66 | !! add it to the general trend of tracer equation. |
|---|
| 67 | !! |
|---|
| 68 | !! ** Method : The horizontal component of the lateral diffusive trends |
|---|
| 69 | !! is provided by a 2nd order operator rotated along neural or geopo- |
|---|
| 70 | !! tential surfaces to which an eddy induced advection can be added |
|---|
| 71 | !! It is computed using before fields (forward in time) and isopyc- |
|---|
| 72 | !! nal or geopotential slopes computed in routine ldfslp. |
|---|
| 73 | !! |
|---|
| 74 | !! 1st part : masked horizontal derivative of T ( di[ t ] ) |
|---|
| 75 | !! ======== with partial cell update if ln_zps=T. |
|---|

|---|
| 77 | !! 2nd part : horizontal fluxes of the lateral mixing operator |
|---|

|---|

|---|

|---|
| 84 | !! difft = 1/(e1t*e2t*e3t) { di-1[ zftu ] + dj-1[ zftv ] } |
|---|
| 85 | !! Add this trend to the general trend (ta,sa): |
|---|
| 86 | !! ta = ta + difft |
|---|
| 87 | !! |
|---|
| 88 | !! 3rd part: vertical trends of the lateral mixing operator |
|---|
| 89 | !! ======== (excluding the vertical flux proportional to dk[t] ) |
|---|
| 90 | !! vertical fluxes associated with the rotated lateral mixing: |
|---|
| 91 | !! zftw =-aht { e2t*wslpi di[ mi(mk(tb)) ] |
