c Subroutine fizhi_wrapper - 'Wrapper' routine to interface |
| 8 |
c with physics driver. |
| 9 |
c 1) Set up "bi, bj loop" and some timers and clocks. |
| 10 |
c 2) Call do_fizhi - driver for physics which computes tendencies |
| 11 |
c 3) Interpolate tendencies to dynamics grid in vertical |
| 12 |
c 4) Convert u,v tendencies to C-Grid |
| 13 |
c |
| 14 |
c Calls: do_fizhi (get u,v,t,s tend, step tke, etc and tc, etc. forward) |
| 15 |
c phys2dyn (4 calls - all physics tendencies) |
| 16 |
c AtoC (u and v tendencies) |
