| 32 | ! Description: |
---|
| 33 | ! ------------ |
---|
| 34 | !> Calculates large scale forcings (geostrophic wind and subsidence velocity) as |
---|
| 35 | !> well as surfaces fluxes dependent on time given in an external file (LSF_DATA). |
---|
| 36 | !> Moreover, module contains nudging routines, where u, v, pt and q are nudged |
---|
| 37 | !> to given profiles on a relaxation timescale tnudge. |
---|
[2342] | 38 | !> Profiles are read in from NUDGING_DATA. |
---|
[2320] | 39 | !> Code is based on Neggers et al. (2012) and also in parts on DALES and UCLA-LES. |
---|
| 40 | !> @todo: Revise reading of ASCII-files |
---|
| 41 | !> @todo: Remove unused variables and control flags |
---|
| 42 | !> @todo: Revise large-scale facing of surface variables |
---|
| 43 | !> @todo: Revise control flags lsf_exception, lsf_surf, lsf_vert, etc. |
