wrf output

I have simulated a cold front in WRF at 1 km resolution and wanted to check the sub-grid scale turbulent momentum (u'w', v'w') and heat fluxes (q'w'). It appears to me that WRF doesn't output these fluxes. For that I have modify the modules to output these fluxes right? Or is there any option...

Hi I’m working with WRF output files to analyze the land surface energy balance, and I’m writing to confirm the directions (signs) of the fluxes included in my analysis. Based on the basic surface energy balance equation: Rn = H + LE + G I am using the following WRF variables: SWDNB SWUPB...

I am running WRF-Chem Online, I have 5 domains D01, D02, rest three(D03, D04, D05) are nested inside D02, wrf.exe cannot generate wrf outputs beyond D02. Here is my namelist and rsl.error attached for your kind suggestions.

Hai, I have been trying to simulate a lightning event using WRF-Elec, but after my execution, the IC and CG lightning values are 0. What could be the probable reason?

For my current research into WRF-SAAG (NSF NCAR GDEX dataset d616000 - 'Multi-decadal Convection-permitting Simulation of Current Climate over South America using WRF') data access and variables, and I have a question regarding the Deep Soil Moisture (SMCWTD) variable. I was wondering in this...

Hello all, I'm using WRF4.7.1 to run a 1-year simulation (2016-01-01 to 2016-12-31) which encounters segmentation fault at 2016-05-23_08:00:00, because I set write restart files per 5-day, so the latest restart file is wrfrst_d01_2016-05-20_00:00:00. Therefore, I changed the namelist to do a...

Dear, I have a tough problem about wrf-chem. The error is below: newnucbb mins 2.33E+02 5.00E-02 1.07E-13 7.11E-17 4.58E-22 0.00E+00 newnucbb maxs 2.83E+02 9.75E-01 1.29E-09 8.87E-13 1.32E-10 9.30E+05 newnucbb avgs 2.52E+02 5.64E-01 2.47E-10 2.49E-13 4.69E-12 1.25E+04...

In WRF, it is possible to output RMOL=1/L (where L is the Monin-Obukhov length). What formula is used to calculate this L

Hi everyone, After working a lot with the real WRF configurations, I am now in the process of setting up idealized WRF simulations. I am using WRF v4.6.1 and compiled for the em_les case. When running the simulation with two nested domains, I observe strong streaks in many of the 4D-output...

My Python code works correctly for everything else, but I encountered this problem on the last run. What could be the reason?

Hello WRF forum, I am attempting to run WRF Real past spin up time, and then perturb the temperature and pressure fields in a restart file. However I seem to be missing something, because when I restart WRF the edited and perturbed WRF variables disappear. They seem "not to stick." See this...

Hi, I am experiencing a persistent WRF crash at a specific simulation time. WRF 4.7.1 consistently crashes at 2019-06-19 05:19:32 UTC across multiple attempts with different configurations. The previous day (June 18) completes successfully with identical domain and physics settings, but June...

I am trying to simulate WRF and getting a step-kind of transition near the coastlines of India (ECMWF seasonal simulation data as initial and boundary conditions). Attaching namelist.wps, namelist.input, and some screenshots of output variables (surface and pressure level variables). Please help...

Hi, I'm adding microphysics source/sink terms to WRF output by modifying: Registry/Registry.EM_COMMON - Added variables (EPRDO, EPRDGO, etc.) phys/module_mp_morr_two_moment.F - Calculated variables in microphysics scheme phys/module_microphysics_driver.F - Passed variables through driver...

Hi, I'm using ERA5 pressure-level and surface data as forcing for a WRF simulation over Chicago. Initially, I used the recently published era5_to_int.py tool to convert ERA5 netCDF files to intermediate and then metgrid files, following the workflow described here...

Hi everyone, I’m working with WRF v4.6.0 + WPS 4.6 and running simulations with SLUCM / BEP over a metropolitan area. I have high-resolution urban morphology data (building height, plan area fraction, street width) derived from GIS sources. My main confusion is about the correct workflow to...

I’m running a WRF simulation and would like to output radiation flux across all vertical levels in the model. However, I haven’t been able to find any 3D radiation flux variables in the wrfout files or in the Registry. Has anyone done this before, or can point me to the correct fields or...

Hi, I'm using run_wrf.pbs to run a WRF simulation. Originally, I use this parameter set in the .pbs file: #PBS -l select=8:ncpus=30:mpiprocs=30:mem=64GB But it was running slow, so when I restart this job I changed the parameters to increase node number: #PBS -l...

Hello, I would like to ask about about wrf. More speciafically, the variable 'WD10' represents the wind direction. I would like to confirm that the directions of the output is 0 : North, 90: East, 180: South, 270: West, where I am referring to the origin of the wind ( 0 degrees, the wind comes...
