---|
| 46 | !! |
---|
| 47 | !! ** Purpose : Compute the geographical position (in degre) of the |
---|
| 48 | !! model grid-points, the horizontal scale factors (in meters) and |
---|
| 49 | !! the Coriolis factor (in s-1). |
---|
| 50 | !! |
---|
| 51 | !! ** Method : The geographical position of the model grid-points is |
---|
| 52 | !! defined from analytical functions, fslam and fsphi, the deriva- |
---|
| 53 | !! tives of which gives the horizontal scale factors e1,e2. |
---|
| 54 | !! Defining two function fslam and fsphi and their derivatives in |
---|
| 55 | !! the two horizontal directions (fse1 and fse2), the model grid- |
---|
| 56 | !! point position and scale factors are given by: |
---|
[81] | 57 | !! t-point: |
---|
| 58 | !! glamt(i,j) = fslam(i ,j ) e1t(i,j) = fse1(i ,j ) |
---|
| 59 | !! gphit(i,j) = fsphi(i ,j ) e2t(i,j) = fse2(i ,j ) |
---|
| 60 | !! u-point: |
---|
| 61 | !! glamu(i,j) = fslam(i+1/2,j ) e1u(i,j) = fse1(i+1/2,j ) |
---|
| 62 | !! gphiu(i,j) = fsphi(i+1/2,j ) e2u(i,j) = fse2(i+1/2,j ) |
---|
| 63 | !! v-point: |
---|
| 64 | !! glamv(i,j) = fslam(i ,j+1/2) e1v(i,j) = fse1(i ,j+1/2) |
---|
| 65 | !! gphiv(i,j) = fsphi(i ,j+1/2) e2v(i,j) = fse2(i ,j+1/2) |
---|
| 66 | !! f-point: |
---|
| 67 | !! glamf(i,j) = fslam(i+1/2,j+1/2) e1f(i,j) = fse1(i+1/2,j+1/2) |
---|
| 68 | !! gphif(i,j) = fsphi(i+1/2,j+1/2) e2f(i,j) = fse2(i+1/2,j+1/2) |
---|
[3] | 69 | !! Where fse1 and fse2 are defined by: |
---|
| 70 | !! fse1(i,j) = ra * rad * SQRT( (cos(phi) di(fslam))**2 |
---|
| 71 | !! + di(fsphi) **2 )(i,j) |
---|
| 72 | !! fse2(i,j) = ra * rad * SQRT( (cos(phi) dj(fslam))**2 |
---|
| 73 | !! + dj(fsphi) **2 )(i,j) |
---|
| 74 | !! |
---|
| 75 | !! The coriolis factor is given at z-point by: |
---|
| 76 | !! ff = 2.*omega*sin(gphif) (in s-1) |
---|
| 77 | !! |
---|
| 78 | !! This routine is given as an example, it must be modified |
---|
| 79 | !! following the user s desiderata. nevertheless, the output as |
---|
| 80 | !! well as the way to compute the model grid-point position and |
---|
| 81 | !! horizontal scale factors must be respected in order to insure |
---|
| 82 | !! second order accuracy schemes. |
---|
| 83 | !! |
---|
| 84 | !! N.B. If the domain is periodic, verify that scale factors are also |
---|
| 85 | !! periodic, and the coriolis term again. |
---|
| 86 | !! |
---|
| 87 | !! ** Action : - define glamt, glamu, glamv, glamf: longitude of t-, |
---|
| 88 | !! u-, v- and f-points (in degre) |
---|
| 89 | !! - define gphit, gphiu, gphiv, gphit: latitude of t-, |
---|
| 90 | !! u-, v- and f-points (in degre) |
---|
| 91 | !! define e1t, e2t, e1u, e2u, e1v, e2v, e1f, e2f: horizontal |
---|
| 92 | !! scale factors (in meters) at t-, u-, v-, and f-points. |
