    The first wrfout file is corrupted

    Hi, I had made a 5 day run with frames_per_outfile as 1 and I had the first wrfout file damaged/corrupted. So I left out that file and carried forward with the post-processing. But for other runs i tried, I am facing the same issue - having its first wrfout file corrupted. Only the first files...

    How to watch WRF run.

    Good morning everyone, I was reading through the namelist user guide and saw this today. Checking Output¶ Once a model run completes, it is advised to quickly check a few things. If WRF was built with distributed memory (dmpar), there should be an rsl.out.* and rsl.error.* file for each...

    Error while running WRF-Single Layer Urban Canopy Model using NLCD 2011 40 categories data

    Dear WRF Community, I am working on investigating the urban effects of heavy precipitation near the Chicago area using the urban canopy model. I am trying to run WRF-SLUCM using WRFV4.4, initialized by NLCD 2011 40 categories of land use data. Everything was perfect in WPS. I have faced some...

    How to utilize GEFS ensemble mean data for input

    Good afternoon, Has anyone sucessfully used GEFS data for WRF model input? I'm seeing how it compares to the deterministic GFS data for forecast validation.

    Error while Running WRF

    Good day. I am very confused as to how I could prevent this error while running WRF. In my case, I attempt to run 2-domains with outer domain having 15-km and inner domain with 3-km spatial resolution. My Ubuntu system has 16-Gb RAM and I often run WRF with two processors with (mpirun -np 2...

    Modifying WRF 'real.exe' Simulation to Remove Typhoon Effects: Clarification on Wind Field Changes

    Hello everyone, As a beginner in WRF modeling, I have some questions regarding the simulation of typhoons using the WRF model. I successfully ran the 'real.exe' simulation on WRF, and it performed well. However, I'm trying to eliminate the effect of a typhoon while running the 'real.exe'...

    Segmentation fault while running wrf.exe at 1km resolution

    Hi, I am using the WRF v4.0 model for simulations over the mountainous region of India. Model IC/BC is being used from ERA5 datasets. Simulation has three domains, i.e., D1 = 20 km, D2 = 4 km, and D3 = 1 km resolution. WPS and WRF-real completed without any error messages while running wrf.exe...

    How to run WRF with one initial time data?

    Hi, all 1、I wrote a basic initial field environment file based on the solution of the equatorial wave equation. I positioned its initial time at 2021-01-01_00 and converted it into a file in met*nc format. 2、I want to Run it for 90 days to see if it can produce some weather-scale fluctuations...

    WRF fails without providing error message

    Hello, I've been having some issues with getting WRF simulations to complete (no issues with completing real.exe). Initially, I was receiving cfl and TBOUND exceeds table limit error messages, but those have both now been resolved. Unfortunately, I'm still unable to get a simulation to run more...
