wrf output

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...

Size of wrfout file decrease from 379M to 79M using WRFV4.6.1 as show in the figure blow. Moreover, model was't interrupted. It is so confused. if you have some ideals about that, looking forward to your reply! Thanks a lot!

Hi all, I ran a simulation with opt_run = 5 and obtained negative values for water table depth (ZWT), see Fig below(first output, simulation starts at 2013-01-01_00:00:00). ZWT in wrfinput is zero. As I understand it, ZWT is defined as positive downward. When using opt_run = 1, ZWT remains...

I am attempting to run WRF with a perturbed wrfinput file that was generated by da_wrfvar in the WRFDA suite. Both WRF and WRFDA are version 4.6.1, downloaded and compiled from the GitHub repository, but I receive the following error when running wrf.exe: DYNAMICS OPTION: Eulerian Mass...

Hi all, I'm encountering a strange issue with auxiliary history output (auxhist7) during a long-term WRF simulation from 2013 to 2022. My Configuration: Regular output: Daily files auxhist7: Hourly output (for specific variables) auxhist7 settings: iofields_filename = "my-file_d01.txt"...

I am new to WRF (so bear with my question) and I am running two different WRF simulation, to down scale GFS data with 3 nested domains. The two simulations have same settings but they differ in the time control both for wps and wrf. One is ran for 10 days: start_date = '2024-11-01_00:00:00'...

Hi, I successfully ran WRF-Solar v4.5, and the rsl files also show that the external input AOD files were read, but the output results show almost no difference. I’d like to know why this happens. I noticed that although it shows the data being read, the data is not actually being used in the...

Hi everyone. My heartfelt thanks to all the contributors in this forum. You people are awesome!! I am a novice in modeling.I am simulating thunderstorms using 3 domains (9km, 3km and 1km) using WRF V4.3. I have generated MODIS 21 Class geo files using WPS4.3. I intend to ingest LCZ data for...

Hi, I’m using the tslist feature in WRF and would like to customize the output. Specifically, I would like the time series output of vertical profiles at specific locations, but only once per hour, rather than at every model time step. Is there a way to control the temporal frequency and the...

Dear WRF experts, I modified the 2 meter temperature in input ECMWF data in my WRF runs. Specifically, I added +1 degree and +3 degrees. However, the results seem to be insensitive to this (see figure below). I would like to ask: 1. How is 2 meter temperature computed by the WRF model? 2. Am I...

real.exe runs successfully, but when I try to run wrf,exe gets the following error. Please help me to resolve this issue INITIALIZE THREE Noah LSM RELATED TABLES Input data is acceptable to use: WRF NUMBER OF TILES FROM OMP_GET_MAX_THREADS = 1 Tile Strategy is not specified. Assuming 1D-Y...

Hi all, I'm encountering an issue when running WRF from version 4.0 onwards: my TKE output field is all zeros, although the TKE_PBL variable seems to be outputting normal values. I’ve checked the following: The model was compiled correctly and runs without errors. Other turbulence-related...

Hi, I am running the model and got the following error. I have also attached the rsl error file. = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = EXIT CODE: 1 = CLEANING UP REMAINING PROCESSES = YOU CAN IGNORE THE BELOW CLEANUP MESSAGES

Hi everyone. I am currently simulating several cold spell events in eastern China using WRF-SLUCM. However, in some cases, we found that the model results poorly captured the temperature variations when compared to meteorological station observations. As shown in the figure , the cold spell...

I am a student new to WRF. I want to perform simulations that consider irrigation conditions. I have added the IRRIGATION content in the GEOGRID and downloaded the IRRIGATION data in the static geographical data. Verification shows that the IRRIGATION field has been successfully integrated into...

I am using the Morrison double-moment aero microphysics scheme (mp=40). This scheme allows for initial droplet prediction through a variable INUM (line 354). By default, INUM=1.There is also a variable QDCNST=250, which is the initial constant cloud droplet concentration at Line 359. Since I am...

Dear WRF Community, I’m currently troubleshooting a persistent crash in WRF v4.5 that consistently occurs after the third model day, with the following error: I'm running at 15 km resolution, using Noah-MP (sf_surface_physics=4) and the following physics setup: What I’ve Tried and Observed...

I'm running 1km simulations (soon to move down to 250m) and I'm having memory issues using 'getvar' to extract the variables. I can get T2, rh2, td2, uvmet10, uvmet10_wspd_wdir and slp for all times but the remaining variables (excluding lat/lon/ter), require a single time index. I've attempted...

Hi, Using the same namelists, in 1km grid-spacing, for WRFv3.8.1, DLP3 lightning scheme is underestimating lightning count whereas for WRFv4.5, DLP3 is overestimating. Can anyone please explain the reason to me? Thanks.

Whenever I finish running the model as 'mpirun -np 14 ./wrf.exe' I get a file that does not have '.nc' extension at the end of it, for example: 'wrfout_d01_2025-04-22_06:00:00' (it doesnt have .nc at the end), and when trying to open it in python (with xarray and netcdf) or in another program...
