Damping Driver

The damping_driver_nml only ever needs to be specified if do_damping=.true. in idealized_moist_phys_nml. This namelist accounts for subgrid-scale processes which decelerate fast winds at upper levels. It is described on Isca's website and is used in the Frierson example script. Some of the most common options are also described below:

Options

do_rayleigh

bool
On/off switch for Rayleigh friction.
Default: False

Diagnostics

The diagnostics for this module can be specified using the module_name of damping in the diagnostic table file. The list of available diagnostics is available on Isca's website. Some are also given below:

udt_rdamp

Zonal wind tendency for Rayleigh damping.
Can only be returned if do_rayleigh=True.
Dimensions: time, lat, lon, pressure
Units: \(ms^{-2}\)
