# Line 19  C     | SUBROUTINE DYNAMICS Line 25  C     | SUBROUTINE DYNAMICS
25  C     | o Controlling routine for the explicit part of the model  C     | o Controlling routine for the explicit part of the model
26  C     |   dynamics.  C     |   dynamics.
27  C     *==========================================================*  C     *==========================================================*
 C     | This routine evaluates the "dynamics" terms for each  
 C     | block of ocean in turn. Because the blocks of ocean have  
 C     | overlap regions they are independent of one another.  
 C     | If terms involving lateral integrals are needed in this  
 C     | routine care will be needed. Similarly finite-difference  
 C     | operations with stencils wider than the overlap region  
 C     | require special consideration.  
 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     |   W[n] = W* + dt x d/dz P  (NH mode)  
 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*
