| 12 | ! MODULE designed to call SUBROUTINE drag_noro_mod Interface for sub-grid scale orographic scheme |
|---|
| 13 | ! The purpose of this subroutine is: |
|---|
| 14 | ! 1) Make some initial calculation at first call |
|---|
| 15 | ! 2) Split the calculation in several sub-grid ("sub-domain") to save memory and be able run on |
|---|
| 16 | ! a workstation at high resolution.The sub-grid size is defined in dimradmars_mod. |
|---|
| 17 | ! 3) Transfer the increment output of drag_noro_mod into tendencies |
|---|

| 20 | ! VERSION Update: This version uses the variable's splitting, which can be usefull when performing |
|---|
| 21 | ! very high resolution simulation like LES. ! |
