    3-day ahead weather forecast using WRF-ARW based on historical data.

    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.

    WRF model runtime issue: Only able to run 9 days out of 152 due to HPC time limit

    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...

    Running WRF with mpiexec

    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...

    SIGSEGV error related to emissions?

    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...

    How can I obtain WRF forecast run for the next 3 days?

    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...

    Problem about "nmm_cyclone" in "WRF/test"

    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...

    Create some tropical cyclone cases

    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 ...

    Some questions about the wrf idealized cases (tropical cyclone)

    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...

    How to activate the time series output in wrf

    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...
