wrf.exe

In my WRF simulations, if in the nested domain (i.e. 3rd domain) dt crosses 0.1 sec then CFL error is coming. Whereas, 1st and 2nd domain can run sucessfuly with dt=15 sec. Therefore, is there any way to restrict the timestep differently in different domain? I am also wondering is an adaptive...

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...

WRF-4.5 I'm simulating three domains as set in the namelist.input1, for a 700 mm rainfall event in one day, rainfall starting at 9 am. Initial data is from ERA5. The simulation only runs successfully if I simulate the first two domains, so I used ndown to simulate domain d03 separately. I ran...

Hi everyone, I have geo_em files generated by WPSv4.4 that include urban building information. Using Python scripts, I converted the "LU_INDEX" and "LANDUSEF" in the geo_em files to make them compatible with WPSv4.5. After running the full workflow in WRFv4.5.2, the results suggest that building...

当我使用 Modis 数据模拟 WRFv4.5 模型时，我使用 CGLC-MODIS-LCZ_100m 数据更改了土地覆盖类型，其中 NUM_LAND_CT=61. WPS 部分没有报告任何错误，运行正常。 REAL 也正常运行，但 WRF 报告了太多输入土地利用类型错误，如何修复该错误？

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’m simulating the urban heat island with WRF 4.4.1 and have encountered problems about different URBPARAM*.TBL files used in UCM. I’d appreciate any clarification on in what cases will each of these files takes effect. I understand that the sf_urban_physics in namelist.input controls whether...

Greetings, I've been troubleshooting the past couple days trying to figure out a solution to the following error I'm receiving: I'm running WRF v4.6.1 -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 70 program wrf: error opening wrfinput_d01 for...

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...

Hello, I would like to conduct sensitivity test about terrain height on an em_real case. The number of domain are one. The simulations preiod is from July 27, 1800UTC to July 29, 0600UTC. I want to evaluate the effact terrain height in the period just after July 28 0900UTC (Restart Time Point)...

Hi everyone, I'm getting this error when I run wrf.exe. Here is the complete error message. -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode 1. NOTE: invoking MPI_ABORT causes Open MPI to...

Good morning, I am trying to install WRF-Hydro coupled using the configure command. Here are the steps I did. Installed all the libraries and passed on the environment and compiler tests. downloaded the .tar.gz file from here...

Dear scientist, Hi, I hope you are doing well. My name is Samira. I am trying to run WRF-Chem in two different months, but continuously. I will be appreciate if you can help me I have one question about running WRF-Chem from 25 January to 10 February (for example, the year 2022, which involves...

Hi all I'm trying to get to the bottom of some weird issues when running WRF. - I was initially trying to run it on a large memory 64-core VM. WRF fails to complete both in serial and dmpar modes - I ran it on a cluster I have access to. With the same data / namelist files, WRF completed when...

Hello! I'm currently trying to create an SST file for MPAS.I read two posts:Merge Vtable.GFS and Vtable.SST and RE: Enquiry about SST Update in WRF, and they were very helpful to me. Additionally, I also reviewed this presentation...

Hi, I am currently using ERA5 data to get parameters such as QCLOUD. The previous steps (geogrid, ungrib, metgrid, real programs) run successfully. However, when I run wrf.exe, following error occurred. I have attached my namelist.input, rsl.error.0000 and rsl.out.0000 for review. Thank you...

Hello all, I had some problems running wrf—ucm,When I open the 'sf_urban_physics = 1', the WRF will automatically stop and exit after simulating for a period of time, and there is no error message. I attach the namelist.input and one of the rsl.error files and rsl.out files I thank in advance...

Hello, I have encountered the following error while running wrf.exe: For domain 1 , the domain size is too small for this many processors, or the decomposition aspect ratio is poor. Minimum decomposed computational patch size, either x-dir or y-dir, is 10 grid cells. e_we = 93...

I have been trying to run a one day of simulations over the Java island. While Java has a complex terrain with mountain reach 3km height, the inner domain is over flat terrain. The wrf.exe hangs at 9 UTC no matter all the different combinations of schemes I have tried. I am running a 3 domain...

I have been trying to solve a bug with WRF Plus installation for the ./configure_new script. I have set WRF_ROOT from my build of 4.6.1 and I was successful in installing WPS using ./configure_new My commands are these that I used for WRF PLUS [workhorse@localhost WRFPLUS]$ ./configure_new...
