    Could I run ideal case with WRF-chem?

    Hi, I just start learning WRF. I wanner repeat the results of this article. "Simulating nuclear cloud rise within a realistic atmosphere using the Weather Research and Forecasting model " I ran WRF4.2 in ubuntu18.04. And, I tried to set up a warm bubble in em_quarter_ss case. Now I want to add...

    WRF idealized test case outputs with project RotatedLatLon, why?

    Hello! I've successfully set up WRF and have also run a couple of the test cases included in WRF4.4.1 (em_fire, em_quarter_ss). These runs are successful as well and output the standard `wrfout_d01_0001-01-01_00:00:00` type files. I then attempt to visualize these files (example, SLP) using...

    How to Prescribe HFX, QFX, and LH in an idealized WRF simulation

    Dear WRF Community, I am trying to run a simulation to study the urban heat island problem. To do this, my plan is to run an idealized WRF simulation prescribing heating over a flat surface or a mountain. Any help would be highly appreciated. Thanks in advance. With Kind Regards Shak

    Strange perturbation development in idealized simulation with open lateral boundary (ARW 3.9.1.1)

    I'm working on idealized simulation using WRF-ARW version 3.9.1.1, actually NASA-Unified WRF based on that version. My final goal is simulation of pyro-cumulus and tracking tracers emitted from wildfire. Now I'm doing sanity check simulations with an idealized configuration without giving any...

    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...

    Wrf output

    Hi everyone, I need help with changing the axis of my plots from the domains to the variable unit. For example from bottom_top to meters or kilometers and from west-east to like temp in Kelvin. Attached is a copy of what i have now

    Memory Error when running idealized WRF test case on Cheyenne

    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...

    Coordinates on multi-domain idealized cases

    I need to know the location of a given surface grid point (i,j) in an idealized simulation. The single-domain answer is easy: (i*dx, j*dy) [m] from the (0,0) reference point. However, this can become more complicated in the multi-domain case. Usually WPS filled the XLONG and XLAT values, but...

    Hill2d - idealized case

    Hi, I am in need of help urgently. I am stuck at this point trying to modify the hill2d test case, my main goal is to have this test case contain some attributes of snow. that is to make the mountain snow, so far I haven't been able to achieve that since I don't know which Microphysics...

    WRF-SCM Forcing with Reanalysis Data

    Hi, I am new to WRF-SCM and I am having a couple of trivial questions regarding the forcing input file in the Single Column Model. My first question is whether the forcing inputs can be provided from any readily available reanalysis datasets. If yes then how can the geostrophic components of...

    PBLH in WRF LES

    Hi all, I am very new to WRF. I am trying to simulate an idealized LES case similar to the test case in WRF. When I observe data for PBLH, I see all 0s. Does WRF-LES calculate PBHL? Do I need to modify anything in the namelist.input to get this done? Any input would be greatly appreciated...

    Simulating tracer plume

    I tried to simulate a plume with the WRF_LES model. I followed the modification of HP1801(https://forum.mmm.ucar.edu/phpBB3/viewtopic.php?f=46&t=8778&p=15752&hilit=plume#p15752). However, there are errors in running wrf.exe. taskid: 0 hostname: n0183 module_io_quilt_old.F 2931 F...

    Running Idealized WRF on CORI

    Hello, I am attempting to run WRF on Cori at NERSC and am running into some issues. Here's the all of the relevant information I can think of: WRF Version: 4.4 (c11bb76939647c4073e9a105ae00faaef55ca7fd) Modules: 1) modules/3.2.11.4 2)...

    Methane plume simulation LES

    Hello, I'm new to the WRF and doing my academic research on greenhouse gases, especially CH4. I want to recreate LES from this paper https://amt.copernicus.org/articles/11/5673/2018/. Could anyone help or guide me?
