C--- The algorithm...
C
C "Correction Step"
C =================
C Here we update the horizontal velocities with the surface
C pressure such that the resulting flow is either consistent
C with the free-surface evolution or the rigid-lid:
C U[n] = U* + dt x d/dx P
C V[n] = V* + dt x d/dy P
C
C "Calculation of Gs"
C ===================
C This is where all the accelerations and tendencies (ie.
C physics, parameterizations etc...) are calculated
C rho = rho ( theta[n], salt[n] )
C b = b(rho, theta)
C K31 = K31 ( rho )
C Gu[n] = Gu( u[n], v[n], wVel, b, ... )
C Gv[n] = Gv( u[n], v[n], wVel, b, ... )
C Gt[n] = Gt( theta[n], u[n], v[n], wVel, K31, ... )
C Gs[n] = Gs( salt[n], u[n], v[n], wVel, K31, ... )
C
C "Time-stepping" or "Prediction"
C ================================
C The models variables are stepped forward with the appropriate
C time-stepping scheme (currently we use Adams-Bashforth II)
C - For momentum, the result is always *only* a "prediction"
C in that the flow may be divergent and will be "corrected"
C later with a surface pressure gradient.
C - Normally for tracers the result is the new field at time
C level [n+1} *BUT* in the case of implicit diffusion the result
C is also *only* a prediction.
C - We denote "predictors" with an asterisk (*).
C U* = U[n] + dt x ( 3/2 Gu[n] - 1/2 Gu[n-1] )
C V* = V[n] + dt x ( 3/2 Gv[n] - 1/2 Gv[n-1] )
C theta[n+1] = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
C salt[n+1] = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
C With implicit diffusion:
C theta* = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
C salt* = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
C (1 + dt * K * d_zz) theta[n] = theta*
C (1 + dt * K * d_zz) salt[n] = salt*
