running wrf

Can WRF-ARW perform a 3 day forecast based on historical data? I am trying to run wrf model beyond the given input days but it is getting stopped.

Hi all, I was trying to run real.exe, but it exited with code 1. I downloaded real-time data (fnl_xxxx_xx_xx.grib2) from NCEP FNL Operational Model Global Tropospheric Analysis online data sets. I successfully ran geogrid.exe, ungrid.exe, and metgrid.exe. but failed in initializing to generate...

Hi everyone, I am having an issue with running my WRF model on two clusters with 35 nodes each. I set the maximum time limit to 24 hours, but my model runtime is 152 days, or about 3 months long. As a result, I've only been able to run and output about 9 days out of the 152 days. I had to...

Hello, my question is the following. If I run WRF with MPI and other nodes (Cluster ) is the execution time shorter? I did a test and it seems to me that I didn't see any difference in execution time. I don't know if I did something wrong. My test was as follows First I used a node with 8...

Hi everyone! I was running WRF-Chem3.9.1 with KPP, reinitialized the meteorology every 24 hours but with chemistry field from previous time step when doing re-initialization. After running several days, a SIGSEGV occurred (see all_rsl.error.txt attached). Since I found in the error log file...

Hi, WRF forum! I am a WRF beginner. From what I understand so far, I can only produce results /simulations for just the same timeframe as the forcing dataset ( and selected in the namelist.input & namelist.wps). Assuming I do not want to force with future projection datasets like the Bias...

Hi, I'm getting the following error when i run real.exe. I have attached error image, namelist.wps , namelist.input and rsl error file

Dear all,

Hi all, I have a doubt in the met_em files generated. I'm trying to reproduce the results of the simulation from the article -"Recovery processes in a large offshore wind farm". I'm using WRF 4.4.1 and WPS 4.4 for the current simulation. I have successfully compiled the WRF and WPS with the...

Dear friends. I compile "nmm_tropical_cyclone" under "wrf/test" (First use the command "./configure ", then "./compile nmm_tropical_cyclone" in "WRF"). In the process, there are frequent warning and two errors at the end, so “ideal.exe” cannot be generated, but “WRF.exe” can be generated...

Dear friends, I want to create a series of TC landfall situations (do not have to think about the real cases), But the landing points need to be located in a certain district . Are there any good methods? I hope you can give me some advice, I am very anxious to know the answer to this question ...

I can successfully run the default tropical cyclone case, but I have the following problems: 1. How to change the position of the inserted TC? README says it located at the model domain center. But I don't know how to modify it in my own case. 2. I want TC to land in my requested area or...

Hi all, I am trying to reproduce some plots in "Explicit Forecasts of Winter Precipitation Using an Improved Bulk Microphysics Scheme. Part II: Implementation of a New Snow Parameterization" using the idealized test case. But I am stuck on how to input an initial velocity in the file. Any help...

I noticed that wrf can produce a time series output at a certain location by presenting a 'tslist' file as shown in README.tslist. Is there any one have made it worked. In my experiments, I provided a file named 'tslist' in run directory, however, when the program is completed, I can not see...

Hi everyone, I'm getting this error when I run real.exe. Here is the complete error message. starting wrf task 0 of 1 -------------------------------------------------------------------------- MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD with errorcode...

I am using WRF 4.1.3 to run the model with WSM6 microphysic scheme (mp_physics = 6) and applying HAILCAST module in the inner domain. I'm obtaining results for WRF-HAILCAST MAX Hail Diameter, however I can not take any hail (HAILNC). I obtain zero for all domains. I tried to turn on hail_opt...

Dear all, I am in attempt to using WRF4.4.1 to run weather modelling by following the compiling tutorial: Compiling WRF. My WRF Compiler Choice is 34 and nesting option is 1 while my WPS compiler choice is serial. I have successfully configured and compiled WRF and WPS and passed all the...

This error reported by "real.exe" that "grid%tsk unresonable". After that, "wrfinput_d01" and wrfbdy_d01 were not created. Look forward to your answer.🙏.Version: wps 4.3 ; wrf 4.3 . Some troubles may occur in running Geogrid.exe.

I am getting a "Mismatch between namelist and input file dimensions" error while executing real.exe. Can someone help me to where the mismatch is exactly. I have attached all the required files

I am trying to create an input file for a long simulation (40 years) using ERA-5 dataset with updating SSTs. The problem is that wrflowinp file will have only 10000 time steps when I run real.exe and the file does not cover my entire simulation. I tried changing the "auxinput4_end_h"...
