    WRF stops with strange error

    Running ERA5 Data from ECMWF Model stops with this error: I tried changing dt to 3*dx and the error went away but the model stopped. I have attached the namelists, rsl files. Any help would be appriciated.

    Why Does the Same WRF Run Produce Different Results?

    Dear WRF Community, I am working on a July 05-06, 2018, moist convective case, which produces heavy precipitation near the Chicago area. I am using WRFV4.4 to simulate this case. I was able to simulate it successfully, and the results were well comparable with observations (Test1). However...

    wrf.exe fails without error message

    Hello, I am attempting to run wrf.exe in parallel, but it keeps failing after running for 5-6 hours wall time. I was able to get real.exe to run successfully using the same specifications (mpirun -np 42). I've been unable to find anything in the rsl files that would indicate why it would fail...

    Daytime temperatures in Clay in Soil texture

    I am currently studying the heat island of Bangkok, Thailand as part of a Southeast Asian urban climate research. This study uses WRF versions 4.2.2 and 4.3.3. Also, Noah LSM and Single layer UCM are used. I have run simulations on many cases, but the simulations do not reproduce the daytime...

    How can I run wrf-les with a generated wrfinput

    I have generated an analysis after the EnKF and now I want to link it as wrfinput to run wrf-les, but a segment fault always happens when the run just begins. I'm sure my disk and memory are sufficient and time_step is suitable. How can I run the wrf-les with this file? I wonder whether I can...

    WRF always stops at the same location with cfl error

    I am running a case that and always seems to stop at the same time. Things I have tried: 1. Increased number of cores (8 to 16 using mpirun -np 16 ./wrf.exe) 2. Increased ptop (5000 to 3000) 3. Increased e_vert (45 to 50) 4. Decreased time_step (90 to 60) 5, Checked rsl files: I have...

    Vertical loop index in subroutine "advect_w" when the polar flag is on

    Hi. I'd like to ask about the vertical loop index (for tile, kts, and ktf) in WRF(v3.8.1). In the subroutine advect_w located in dyn/module_advect_em.F, I found that the vertical loop index is kts:ktf as shown below. ``` IF ( config_flags%polar .AND. (j == jds+1) ) THEN DO...

    wrf.exe always stops at the same point

    Dear all, Hi, I'm trying to run WRFv4.0.3 with fnl grib2 data. But after a few seconds running wrf.exe, it suddenly stops with no error. I tried it in serial, also with 16 mpi but it always stos at the same point. With mpirun, this stops with this message. starting wrf task 0 of 1 (it repeats...

    Altered SST Cells Cause Simulation to Break Several Years into Run?

    Hello there, This post is tangentially related to a previous post I made (found here). In that post I detailed how the ERA5 data I was using showed the Guadeloupe, Dominica, Martinique, etc. islands within the SSTs (being 0 Kelvin) but did not appear in the landmask. After being stumped on...

    Modify static data in WRF but segmentation fault

    Hello ! I want to replace the static data of LAI, ALBEDO, and LU_INDEX in WRF. I chose to directly replace the geo_em.d02.nc data. After the replacement is successful, both metgrid.exe and real.exe can run successfully, and the resulting data is fine. However, in the final step of running...

    Error Running the WRF with UCM

    Hi all, I am running the WRF model with UCM over eastern united states. The problem is the errors I am facing with UCM. The model works with UCM off but when the UCM is on it will stop after a few hours or even days. I attached the namelist and rslerror files.

    Terminated when running WRF.exe with BEP/BEM, EXIT CODE: 134

    Hello, WRF Team Thank you for your contribution! I am running WRF-Urban with BEP/BEM. However, when running wrf.exe it quits after a few minutes. When I change sf_urban_physics to 2, the model runs fine, but I want to check the energy consumption values, so I have to set sf_urban_physics to 3...
