| 20 |
C *==========================================================* |
| 21 |
C | SUBROUTINE DYNAMICS |
| 22 |
C | o Controlling routine for the explicit part of the model |
| 23 |
C | dynamics. |
| 24 |
C *==========================================================* |
| 25 |
C | This routine evaluates the "dynamics" terms for each |
| 26 |
C | block of ocean in turn. Because the blocks of ocean have |
| 27 |
C | overlap regions they are independent of one another. |
| 28 |
C | If terms involving lateral integrals are needed in this |
| 29 |
C | routine care will be needed. Similarly finite-difference |
| 30 |
C | operations with stencils wider than the overlap region |
| 31 |
C | require special consideration. |
| 32 |
C | The algorithm... |
| 33 |
C | |
| 34 |
C | "Correction Step" |
| 35 |
C | ================= |
| 36 |
C | Here we update the horizontal velocities with the surface |
| 37 |
C | pressure such that the resulting flow is either consistent |
| 38 |
C | with the free-surface evolution or the rigid-lid: |
| 39 |
C | U[n] = U* + dt x d/dx P |
| 40 |
C | V[n] = V* + dt x d/dy P |
| 41 |
C | W[n] = W* + dt x d/dz P (NH mode) |
| 42 |
C | |
| 43 |
C | "Calculation of Gs" |
| 44 |
C | =================== |
| 45 |
C | This is where all the accelerations and tendencies (ie. |
| 46 |
C | physics, parameterizations etc...) are calculated |
| 47 |
C | rho = rho ( theta[n], salt[n] ) |
| 48 |
C | b = b(rho, theta) |
| 49 |
C | K31 = K31 ( rho ) |
| 50 |
C | Gu[n] = Gu( u[n], v[n], wVel, b, ... ) |
| 51 |
C | Gv[n] = Gv( u[n], v[n], wVel, b, ... ) |
| 52 |
C | Gt[n] = Gt( theta[n], u[n], v[n], wVel, K31, ... ) |
| 53 |
C | Gs[n] = Gs( salt[n], u[n], v[n], wVel, K31, ... ) |
| 54 |
C | |
| 55 |
C | "Time-stepping" or "Prediction" |
| 56 |
C | ================================ |
| 57 |
C | The models variables are stepped forward with the appropriate |
| 58 |
C | time-stepping scheme (currently we use Adams-Bashforth II) |
| 59 |
C | - For momentum, the result is always *only* a "prediction" |
| 60 |
C | in that the flow may be divergent and will be "corrected" |
| 61 |
C | later with a surface pressure gradient. |
| 62 |
C | - Normally for tracers the result is the new field at time |
| 63 |
C | level [n+1} *BUT* in the case of implicit diffusion the result |
| 64 |
C | is also *only* a prediction. |
| 65 |
C | - We denote "predictors" with an asterisk (*). |
| 66 |
C | U* = U[n] + dt x ( 3/2 Gu[n] - 1/2 Gu[n-1] ) |
| 67 |
C | V* = V[n] + dt x ( 3/2 Gv[n] - 1/2 Gv[n-1] ) |
| 68 |
C | theta[n+1] = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 69 |
C | salt[n+1] = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 70 |
C | With implicit diffusion: |
| 71 |
C | theta* = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 72 |
C | salt* = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 73 |
C | (1 + dt * K * d_zz) theta[n] = theta* |
| 74 |
C | (1 + dt * K * d_zz) salt[n] = salt* |
