C | SUBROUTINE DYNAMICS | |

C | o Controlling routine for the explicit part of the model | |

C | dynamics. | |
| 10 |
C |==========================================================| |
| 11 |
C | This routine evaluates the "dynamics" terms for each | |
| 12 |
C | block of ocean in turn. Because the blocks of ocean have | |
| 13 |
C | overlap regions they are independent of one another. | |
| 14 |
C | If terms involving lateral integrals are needed in this | |
| 15 |
C | routine care will be needed. Similarly finite-difference | |
| 16 |
C | operations with stencils wider than the overlap region | |
| 17 |
C | require special consideration. | |

C--- The algorithm... |
| 140 |
C |
| 141 |
C "Correction Step" |
| 142 |
C ================= |
| 143 |
C Here we update the horizontal velocities with the surface |
| 144 |
C pressure such that the resulting flow is either consistent |
| 145 |
C with the free-surface evolution or the rigid-lid: |
| 146 |
C U[n] = U* + dt x d/dx P |
| 147 |
C V[n] = V* + dt x d/dy P |
| 148 |
C |
| 149 |
C "Calculation of Gs" |
| 150 |
C =================== |
| 151 |
C This is where all the accelerations and tendencies (ie. |
| 152 |
C phiHydysics, parameterizations etc...) are calculated |
| 153 |
C rVel = sum_r ( div. u[n] ) |
| 154 |
C rho = rho ( theta[n], salt[n] ) |
| 155 |
C b = b(rho, theta) |
| 156 |
C K31 = K31 ( rho ) |
| 157 |
C Gu[n] = Gu( u[n], v[n], rVel, b, ... ) |
| 158 |
C Gv[n] = Gv( u[n], v[n], rVel, b, ... ) |
| 159 |
C Gt[n] = Gt( theta[n], u[n], v[n], rVel, K31, ... ) |
| 160 |
C Gs[n] = Gs( salt[n], u[n], v[n], rVel, K31, ... ) |
| 161 |
C |
| 162 |
C "Time-stepping" or "Prediction" |
| 163 |
C ================================ |
| 164 |
C The models variables are stepped forward with the appropriate |
| 165 |
C time-stepping scheme (currently we use Adams-Bashforth II) |
| 166 |
C - For momentum, the result is always *only* a "prediction" |
| 167 |
C in that the flow may be divergent and will be "corrected" |
| 168 |
C later with a surface pressure gradient. |
| 169 |
C - Normally for tracers the result is the new field at time |
| 170 |
C level [n+1} *BUT* in the case of implicit diffusion the result |
| 171 |
C is also *only* a prediction. |
| 172 |
C - We denote "predictors" with an asterisk (*). |
| 173 |
C U* = U[n] + dt x ( 3/2 Gu[n] - 1/2 Gu[n-1] ) |
| 174 |
C V* = V[n] + dt x ( 3/2 Gv[n] - 1/2 Gv[n-1] ) |
| 175 |
C theta[n+1] = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 176 |
C salt[n+1] = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 177 |
C With implicit diffusion: |
| 178 |
C theta* = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 179 |
C salt* = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
| 180 |
C (1 + dt * K * d_zz) theta[n] = theta* |
| 181 |
C (1 + dt * K * d_zz) salt[n] = salt* |
| 182 |

C-- Set up work arrays with valid (i.e. not NaN) values |
| 185 |
C These inital values do not alter the numerical results. They |
| 186 |
C just ensure that all memory references are to valid floating |
| 187 |
C point numbers. This prevents spurious hardware signals due to |
| 188 |
C uninitialised but inert locations. |
