buoyancy(E, m, z, H=14500)

Parcel buoyancy profile, or Eq. (A1) in MW01.

Parameters:
  • E (int, float) – Specified CAPE
  • m (int, float) – Profile compression parameter
  • z (int, float) – Altitude above ground level (metres)
  • H (int, float, optional) – Vertical scale
Returns:

profile – Atmospheric profile.
Return type:

array_like
calc_RH(z, ztr=12000.0)
calc_U(z, us, zs=3000)
calc_theta(z, ztr=12000.0, theta0=300.0, thetatr=343, Ttr=213)

WEM.lazyWRF.lazyWRF.main module

class WEM.lazyWRF.lazyWRF.main.Lazy(config)

Bases: object

copy_files(tofolder)

Move wrfout files to folder. Create folder if it doesn’t exist

Move .TS files if they exist Copy namelist.input to that folder. Copy rsl.error.0000 to the folder.

Input(s): args = names of folder tree, in order of depth.

copy_namelist(suffix)

Appends current time to namelist to create backup.

edit_namelist(suffix, sett, newval, maxdom=1)

Method edits namelist.wps or namelist.input.

Parameters:
  • suffix – which namelist needs changing
  • sett – setting that needs changing
  • newval – its new value -> currently replaces whole line
  • maxdom – number of domains to edit (this is relevant for multiple columns?)
Returns:

None.
generate_date(date, outstyle='wps')

Creates date string for namelist files.

Input:

go(casestr, IC, experiment, ensnames, **kwargs)

Inputs: (all folder names) casestr : string of case study initialisation date/time IC : initial condition model experiment : dictionary. Key: ensemble type (ICBC,STCH,MXMP)

-initial condition/boundary condition -stochastic kinetic energy backscatter -mixed model parameterisations
Value...
-model configuration (CTRL) for ICBC -initial condition model/ens member for others
ensnames : list of ensemble member names
  • e.g. c00,p01,p02

**kwargs include: WPS_only : stop after linking met_em files to WRF folder

go_GEFSR2(ensns, **kwargs)

Runs WPS, WRF for one set of initial conditions and settings based on the GEFSR2 model.

Inputs: ensns : names of ensemble member

Inputs: *args : e.g. ensemble member

run_exe(exe)

Run WPS executables, then check to see if it failed. If not, return True to proceed.

Input: exe : .exe file name.
