|
c summary: |
27 |
|
|
c - compute interior mixing everywhere: |
28 |
|
|
c interior mixing gets computed at all interfaces due to constant |
29 |
|
|
c internal wave background activity ("fkpm" and "fkph"), which |
30 |
|
|
c is enhanced in places of static instability (local richardson |
31 |
|
|
c number < 0). |
32 |
|
|
c Additionally, mixing can be enhanced by adding contribution due |
33 |
|
|
c to shear instability which is a function of the local richardson |
34 |
|
|
c number |
35 |
|
|
c - double diffusivity: |
36 |
|
|
c interior mixing can be enhanced by double diffusion due to salt |
37 |
|
|
c fingering and diffusive convection (ifdef "kmixdd"). |
38 |
|
|
c - kpp scheme in the boundary layer: |
39 |
|
|
c |
40 |
|
|
c a.boundary layer depth: |
41 |
|
|
c at every gridpoint the depth of the oceanic boundary layer |
42 |
|
|
c ("hbl") gets computed by evaluating bulk richardson numbers. |
43 |
|
|
c b.boundary layer mixing: |
44 |
|
|
c within the boundary layer, above hbl, vertical mixing is |
45 |
|
|
c determined by turbulent surface fluxes, and interior mixing at |
46 |
|
|
c the lower boundary, i.e. at hbl. |
47 |
|
|
c |
48 |
|
|
c this subroutine provides the interface between the MIT GCM UV and the |
49 |
|
|
c subroutine "kppmix", where boundary layer depth, vertical |
50 |
|
|
c viscosity, vertical diffusivity, and counter gradient term (ghat) |
51 |
|
|
c are computed slabwise. |
52 |
|
|
c note: subroutine "kppmix" uses m-k-s units. |
53 |
|
|
c |
54 |
|
|
c time level: |
55 |
|
|
c input tracer and velocity profiles are evaluated at time level |
56 |
|
|
c tau, surface fluxes come from tau or tau-1. |
57 |
|
|
c |
58 |
|
|
c grid option: |
59 |
|
|
c in this "1-grid" implementation, diffusivity and viscosity |
60 |
|
|
c profiles are computed on the "t-grid" (by using velocity shear |
61 |
|
|
c profiles averaged from the "u,v-grid" onto the "t-grid"; note, that |
62 |
|
|
c the averaging includes zero values on coastal and seafloor grid |
63 |
|
|
c points). viscosity on the "u,v-grid" is computed by averaging the |
64 |
|
|
c "t-grid" viscosity values onto the "u,v-grid". |
65 |
|
|
c |
66 |
|
|
c vertical grid: |
67 |
|
|
c mixing coefficients get evaluated at the bottom of the lowest |
68 |
|
|
c layer, i.e., at depth zw(Nr). these values are only useful when |
69 |
|
|
c the model ocean domain does not include the entire ocean down to |
70 |
|
|
c the seafloor ("upperocean" setup) and allows flux through the |
71 |
|
|
c bottom of the domain. for full-depth runs, these mixing |
72 |
|
|
c coefficients are being zeroed out before leaving this subroutine. |
