C "Correction Step" |
105 |
|
C ================= |
106 |
|
C Here we update the horizontal velocities with the surface |
107 |
|
C pressure such that the resulting flow is either consistent |
108 |
|
C with the free-surface evolution or the rigid-lid: |
109 |
|
C U[n] = U* + dt x d/dx P |
110 |
|
C V[n] = V* + dt x d/dy P |
111 |
|
C |
112 |
|
C "Calculation of Gs" |
113 |
|
C =================== |
114 |
|
C This is where all the accelerations and tendencies (ie. |
115 |
|
C physics, parameterizations etc...) are calculated |
116 |
|
C w = sum_z ( div. u[n] ) |
117 |
|
C rho = rho ( theta[n], salt[n] ) |
118 |
|
C K31 = K31 ( rho ) |
119 |
|
C Gu[n] = Gu( u[n], v[n], w, rho, Ph, ... ) |
120 |
|
C Gv[n] = Gv( u[n], v[n], w, rho, Ph, ... ) |
121 |
|
C Gt[n] = Gt( theta[n], u[n], v[n], w, K31, ... ) |
122 |
|
C Gs[n] = Gs( salt[n], u[n], v[n], w, K31, ... ) |
123 |
|
C |
124 |
|
C "Time-stepping" or "Prediction" |
125 |
|
C ================================ |
126 |
|
C The models variables are stepped forward with the appropriate |
127 |
|
C time-stepping scheme (currently we use Adams-Bashforth II) |
128 |
|
C - For momentum, the result is always *only* a "prediction" |
129 |
|
C in that the flow may be divergent and will be "corrected" |
130 |
|
C later with a surface pressure gradient. |
131 |
|
C - Normally for tracers the result is the new field at time |
132 |
|
C level [n+1} *BUT* in the case of implicit diffusion the result |
133 |
|
C is also *only* a prediction. |
134 |
|
C - We denote "predictors" with an asterisk (*). |
135 |
|
C U* = U[n] + dt x ( 3/2 Gu[n] - 1/2 Gu[n-1] ) |
136 |
|
C V* = V[n] + dt x ( 3/2 Gv[n] - 1/2 Gv[n-1] ) |
137 |
|
C theta[n+1] = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
138 |
|
C salt[n+1] = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
139 |
|
C With implicit diffusion: |
140 |
|
C theta* = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
141 |
|
C salt* = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] ) |
142 |
|
C (1 + dt * K * d_zz) theta[n] = theta* |
143 |
|
C (1 + dt * K * d_zz) salt[n] = salt* |
