C State Variables: |
| 21 |
C etaN :: free-surface r-anomaly (r unit) at current time level |
| 22 |
C uVel :: zonal velocity (m/s, i=1 held at western face) |
| 23 |
C vVel :: meridional velocity (m/s, j=1 held at southern face) |
| 24 |
C theta :: potential temperature (oC, held at pressure/tracer point) |
| 25 |
C salt :: salinity (ppt, held at pressure/tracer point) |
| 26 |
C gX, gxNm1 :: Time tendencies at current and previous time levels. |
| 27 |
C etaH :: surface r-anomaly, advanced in time consistently |
| 28 |
C with 2.D flow divergence (Exact-Conservation): |
| 29 |
C etaH^n+1 = etaH^n - delta_t*Div.(H^n U^n+1) |
| 30 |
C note: a) used with "exactConserv", necessary for Non-Lin free-surf and mixed |
| 31 |
C forward/backward free-surf time stepping (e.g., Crank-Nickelson) |
| 32 |
C b) same as etaN but not necessarily at the same time, e.g.: |
| 33 |
C implicDiv2DFlow=1 => etaH=etaN ; =0 => etaH=etaN^(n-1); |
