32 |
c |
33 |
c summary: |
34 |
c - compute interior mixing everywhere: |
35 |
c interior mixing gets computed at all interfaces due to constant |
36 |
c internal wave background activity ("fkpm" and "fkph"), which |
37 |
c is enhanced in places of static instability (local richardson |
38 |
c number < 0). |
39 |
c Additionally, mixing can be enhanced by adding contribution due |
40 |
c to shear instability which is a function of the local richardson |
41 |
c number |
42 |
c - double diffusivity: |
43 |
c interior mixing can be enhanced by double diffusion due to salt |
44 |
c fingering and diffusive convection (ifdef "kmixdd"). |
45 |
c - kpp scheme in the boundary layer: |
46 |
c |
47 |
c a.boundary layer depth: |
48 |
c at every gridpoint the depth of the oceanic boundary layer |
49 |
c ("hbl") gets computed by evaluating bulk richardson numbers. |
50 |
c b.boundary layer mixing: |
51 |
c within the boundary layer, above hbl, vertical mixing is |
52 |
c determined by turbulent surface fluxes, and interior mixing at |
53 |
c the lower boundary, i.e. at hbl. |
54 |
c |
55 |
c this subroutine provides the interface between the MITGCM and |
56 |
c the routine "kppmix", where boundary layer depth, vertical |
57 |
c viscosity, vertical diffusivity, and counter gradient term (ghat) |
58 |
c are computed slabwise. |
59 |
c note: subroutine "kppmix" uses m-k-s units. |
60 |
c |
61 |
c time level: |
62 |
c input tracer and velocity profiles are evaluated at time level |
63 |
c tau, surface fluxes come from tau or tau-1. |
64 |
c |
65 |
c grid option: |
66 |
c in this "1-grid" implementation, diffusivity and viscosity |
67 |
c profiles are computed on the "t-grid" (by using velocity shear |
68 |
c profiles averaged from the "u,v-grid" onto the "t-grid"; note, that |
69 |
c the averaging includes zero values on coastal and seafloor grid |
70 |
c points). viscosity on the "u,v-grid" is computed by averaging the |
71 |
c "t-grid" viscosity values onto the "u,v-grid". |
72 |
c |
73 |
c vertical grid: |
74 |
c mixing coefficients get evaluated at the bottom of the lowest |
75 |
c layer, i.e., at depth zw(Nr). these values are only useful when |
76 |
c the model ocean domain does not include the entire ocean down to |
77 |
c the seafloor ("upperocean" setup) and allows flux through the |
78 |
c bottom of the domain. for full-depth runs, these mixing |
79 |
c coefficients are being zeroed out before leaving this subroutine. |
