|---|
| 72 | !! ** Purpose : Compute the before tracer (t & s) trend associated |
|---|
| 73 | !! with the bottom boundary layer and add it to the general trend |
|---|
| 74 | !! of tracer equations. The bottom boundary layer is supposed to be |
|---|
| 75 | !! a purely diffusive bottom boundary layer. |
|---|
| 76 | !! |
|---|
| 77 | !! ** Method : When the product grad( rho) * grad(h) < 0 (where grad |
|---|
| 78 | !! is an along bottom slope gradient) an additional lateral diffu- |
|---|
| 79 | !! sive trend along the bottom slope is added to the general tracer |
|---|
| 80 | !! trend, otherwise nothing is done. |
|---|
| 81 | !! Second order operator (laplacian type) with variable coefficient |
|---|
| 82 | !! computed as follow for temperature (idem on s): |
|---|
| 83 | !! difft = 1/(e1t*e2t*e3t) { di-1[ ahbt e2u*e3u/e1u di[ztb] ] |
|---|
| 84 | !! + dj-1[ ahbt e1v*e3v/e2v dj[ztb] ] } |
|---|
| 85 | !! where ztb is a 2D array: the bottom ocean temperature and ahtb |
|---|
| 86 | !! is a time and space varying diffusive coefficient defined by: |
|---|
| 87 | !! ahbt = zahbp if grad(rho).grad(h) < 0 |
|---|
| 88 | !! = 0. otherwise. |
|---|
| 89 | !! Note that grad(.) is the along bottom slope gradient. grad(rho) |
|---|
| 90 | !! is evaluated using the local density (i.e. referenced at the |
|---|
| 91 | !! local depth). Typical value of ahbt is 2000 m2/s (equivalent to |
|---|
| 92 | !! a downslope velocity of 20 cm/s if the condition for slope |
|---|
| 93 | !! convection is satified) |
|---|
| 94 | !! Add this before trend to the general trend (ta,sa) of the |
|---|
| 95 | !! botton ocean tracer point: |
|---|
| 96 | !! ta = ta + difft |
|---|
| 97 | !! |
|---|
| 98 | !! ** Action : - update (ta,sa) at the bottom level with the bottom |
|---|
| 99 | !! boundary layer trend |
|---|
| [503] | 100 | !! - save the trends in ztrdt/ztrds ('key_trdtra') |
