SUBROUTINE FORWARD_STEP( iloop, myTime, myIter, myThid )
C !DESCRIPTION: \bv
C *=================================================================
C | SUBROUTINE forward_step
C | o Step forward in time the model variables for one time-step
C *=================================================================
C | The algorithm...
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+1] = theta*
C | (1 + dt * K * d_zz) salt[n+1] = salt*
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 | W[n] = W* + dt x d/dz P (NH mode)
