wrf bug

dear friends, when I used the era5 data to run WRF4.2 and WPS4.2 (ps: I used the Vtable.ERA-interim.pl as Vtable, all the variables like 10m u-component of wind, 10m v-component of wind, 2m dewpoint temperature, 2m temperature, Sea surface temperature, Skin temperature, Soil temperature level 1...

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...

Greetings everyone. I'd like some help with a problem i'm facing while running wrf.exe. I'll attach my namelist, rsl.error and rsl.out files, since i'm not even able to track down the problem. Thanks in advance

namelist.input : &time_control run_days = 24, run_hours = 0, run_minutes = 0, run_seconds = 0, start_year = 2023, start_month = 08...

Hello，I'm doing a simulation of wrf-les coupling. The CFD tool used is sowfa, and in its examples, there is a case of coupling with wrf, where there is a program to extract data from wrf. But after I changed my filename, nHrs and nPerhrs. Running error : wrfout file does not have z and fc...

Greetings everyone I'd like some help with a problem i'm facing while running real.exe: when i do input the command "./real.exe" i get the message: -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 5805 invalid parent id for domain 2 Thanks in...

Hi, I came across segfault for WRF 4.5 using the new modis-lcz dataset under SLUCM urban physics. The segfault always happen at 1 of the 72 cores in Cheyenne. From the error log it seems that the segfault happens during avgflx at solve_em.F. I cannot pinpoint how it happens without any...

Hello, I met this problem here with WRF-v4.4.1. After I made some modifications to Registry/Registry.EM_COMMON (without changing any part of the other codes) and recompile, the simulation results changes. The modification includes two new variables in "NSSL WRF diagnostics" part, and add an...

I am currently using WRF 4.5 to perform regional climate simulations over the Tibetan Plateau. However, I consistently encounter an error when running wrf.exe: Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0 0x151d5f527ad0 in ??? #1...

hello there, i am trying to install wrf chem model, everything goes well when i try to compile, it show this error "Problems building executables, look for errors in the build log" i went to log file and check the error "ERROR: variable name for third body in KPP species file is expected to be...

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...

Hi all, I am using WRF-Chem v4.4.2 under a triple nested domain (36 km, 6 km, and 1 km) in August 2019. In 6 km and 1km simulations, there is a strange T2 cold bias after several hours of reinitialization. Consequently, simulations crash. I tested different versions of WRF from v4.1.4 to v4.5...

Hello，WRF-Hydro Team： When I run WRF-Hydro V5.2 or newer version， there is not SFCRNOFF in LDASOUT_DOMAIN2. And the output of WRF-Hydro V5.1.2 is right. What is wrong with the new version ？ Thanks！

Hi All, Significant differences were found in the SWDOWN calculation between WRF-4.3.1 and WRF-4.4.1. Compared with measured radiation data, WRF-4.4.1 shows much worse scores. Similar differences are in CLDFRA: compared to satellite observation WRF-4.4.1 underestimates the values of the...

Hi all, I am running the WRF-Noah MP model in East Asia during 2021.6-2021.8 without any errors reported. However, I found some strange things in my wrf.output files: (1) Strange time dimension. Generally, my daily wrfout files have a dimension of 159*159*1 (My study area covers 159 grid...

Hello, I have run the real.exe successfully and get the wrfinputd01 and wrfbdyd01.However when I tried run the wrf.exe，the program fails immediately.and I got the error message like: Max map factor in domain 1 = 0.00. Scale the dt in the model accordingly. D01: Time step...

Hello, I am attempting to run the idealized tropical cyclone test case (em_tropical_cyclone) on Cheyenne. I am just using the default namelist settings. I have successfully configured WRF (1st option = 15 and 2nd = 1), successfully compiled the test case, and ideal.exe seems to have run...

I hope you're all doing great. This is my first time using WRF, I have done most of the WPS work, the geogrid, ungrib and metgrid and I linked my met output files to my wrf/run path. My case study has 4 nested domains and I have attached the namelist.wps below. When I run the real.exe and it...

It appears as though the wrfoutReady files are not written when running WRF version 4.4.0 and using IO quilting. Is this the expected behavior? &time_control output_ready_flag = .true., &domains nproc_x = 15, nproc_y = 21, &namelist_quilt...

Hi everyone, When I tried to compile WRF-Chem with the .bashrc setting of WRF_CHEM=1, WRF_EM_CORE=1, WRF_KPP=1, WRF_NMM_CORE=0, the following errors were recorded in the compile.log file. Also, some other fatal errors occurred. The compile.log file and .bashrc file are attached. Could...
