wrf.exe

Hello all, I am attempting to run WRFv4.3.1 with ERA5 initial conditions. I am able to get through WPS with no issues and real.exe "completes without issue". However, upon running runwrf.csh, I am only able to get through the first output time for each domain, followed by "forrtl: error (78)...

Dear Members, I hope everyone is doing great. I am running a real case using WRF 4.3.3. This is the only version that I can compile WRF successfully. IN configration, I chose serial (32) and Basics (1). I have encountered an issue to run a nested case with 3 domains in total. However, when...

Hi, I am using a Linux cluster with GNU compilers to run WRF simulations using mpirun. Currently, I am using 9 nodes with a total of 36 cores, and the CPU usage appears efficient. I have four domains, each with a grid size of 250 × 150. However, I am only getting 11 seconds of simulation...

大家好： 我运行的是 WRF4.0，使用 mpirun 运行 wrf.exe 时出现一些错误，详细错误附在下面。您能告诉我如何修复这个错误吗？而 rsl.error 文件只有 rsl.error.0000。 感谢您的想法。

Hello, I've started using WRF over the last year. From NCAR tutorials and WRF user guide, I came to know that using more than one processor would improve my model performance and also optimize the total model run time while using mpirun. So, accordingly, I've followed the guide present on this...

I get the following error when I try to run wrf with updated IC and BC after DA. d01 2023-07-07_00:21:50 21 points exceeded v_cfl = 2 in domain d01 at time 2023-07-07_00:21:50 hours d01 2023-07-07_00:21:50 Max W: 43 563 18 W: -61.60 w-cfl: 4.20 dETA: 0.02 Could...

Hello, so ive run the obsgrid.exe ofr the first time and get the message on the obsgrid.out : Time Loop Processing, date = 2024-09-07_06:00:00 Using ./OBS_DOMAINd01:2024-09-07_06 as obs input file Number of observations successfully ingested: 1. Number of empty observations discarded: 0...

I have tried the following methods without success: 1. grep -rn "cfl" rsl.* 2. w_damping = 1 3. ulimit -s unlimited The meteorological data should be fine, as I have successfully run a case previously using this dataset. This time, I increased the resolution and added sst_update = 1, but it...

Hellow I want to figure out how to truly specify non moving domains in vortex following? I am currently setting it up as follows: time_to_move = 99999999,9999999,0,0, But when I want to make some interesting attempts, it doesn't work properly:

Hello, I am going to run the wrf.exe. And I would like to use the shceme combination of Thompson+MYNN-EDMF+Noah. Unfortunately, the wrf.exe crashed at the first time step when calculating the MYNNPBL, throngth out the segment error. I don't know the real problem is. So could anyone give some...

Hi, I am using WRF-LES to conduct simulation experiments at a 30-meter resolution. The compilation was successful since I can run both ideal.exe and wrf.exe with the default namelist.input. However, when I start using double nesting, wrf.exe throws an error, and I have uploaded the error log...

hi all, ive been trying to run wrf chem using anthro and bio emiss data, i got program killed while system calculate megan emissions, ********************************************************************* * PROGRAM:WRF-Chem V4.4 MODEL No git found or not a git repository, git...

Hi dears I am trying run anthro_emis< sami.inp to produce wrfchemi files and I brought my inp file to run the "anthro_emis.exe". but it only produce wrfchemi_00::00:00 file until the end of date which is in sami.inp.(stop_output_time = '2022-03-02_00:00:00) and it is stopped. what shall I do...

Hello, I was tried to running wrf.exe, the program crashed at the begninning with the error "d01 2023-07-27_12:00:00 in YSU PBL forrtl: severe (174): SIGSEGV, segmentation fault occurred" I had already increase the number of cores (up to 512!) and decrease the timestep length, as well set the...

GFS data : 0.25 deg, dx : 6000 m. Timestep : 24s I followed the instructions as in the links to adjust the dx accordingly: [Wrf-users] grid ratio & map factor and Questions about time step Previously, with the same namelists but with GFS data having 12 km instead of 0.25deg (~27 km), the...

Hello! l try to use obs-nudging with WRF run. l use both upper air and surface data in little-r format from website (https://rda.ucar.edu/datasets/ds351-0/)and (https://rda.ucar.edu/datasets/ds461-0/). Meteorological data used in WPS are ERA5 data at 3h time intervals.It successfully generated...

My WRF-4.6 Model is crashing at the radiation time step with both tropical and CONUS suites and for all other configurations. I tried changing radt to other values but saw similar crashing with a similar error. Any help would be appreciated.

I want to add heat flux as initial forcing in WRF-SCM. But I have no idea how to do it. Should I specify heat flux in files like GABLS_II_forcing.txt, make_scm_forcing.ncl, forcing_file.cdl, input_soundig? If anyone knows about this, please let me know! thank you!!

Hi, I would like to know if it is compulsory to keep the simulation time period between WPS and WRF same. Can I run WPS for certain time period range (say 01-Jan-2020_00 to 03-Jan-2020_00) and do different runs of WRF with different starting time (eg: Run-1: 01-Jan-2020_06 to 03-Jan-2020_00...

Hi there, I'm running some cases on our cluster with WRF V4.5.2. I noticed that performance reduced suddenly after a several hours of simulation time. I've attached a figure containing scatter plots of the time to compute each step for each run. You'll notice that the computation time is very...
