    Idealized Case em_seabreeze2d_x

    Dear Community, I am currently working on generating wind velocity simulations based on changes in radiation, specifically for simulating sea-breeze phenomena. Through a Google search, I discovered that the idealized case em_seabreeze2d_x in WRF can assist me in achieving this simulation...

    Possibility of using specified lateral conditions for idealized cases

    Hi WRF experts/ users, is it possible to use the specified lateral boundary conditions for idealized conditions sans nesting? If so, how do we do this?

    How to change Soil heat capacity, thermal diffusivity, thermal inertia

    Hi, WRF support: I want to change Soil heat capacity (C), thermal diffusivity (Kt), and thermal inertia (Iq), in such a way that they remain constant during the integration time. Where should I make these modifications, and what is the specific code?How to change the height of vertical soil...

    3D Idealized squall line?

    Hello, I am aware that I am able to run a 2d squall line in either the x or y direction using WRF, but I am curious if there is a way to produce 3D output from these simulations? Specifically, I am interested in 3D reflectivity. Thank you!

    Is it possible to run a WRF-idealized simulation with a non-stretching grid?

    Dear WRF Community, I am planning to perform some idealized simulations using the em_hill2D test case provided in WRF. I have two questions for these tests. 1. I am wondering if there is a possibility of running the em_hill2D test case with a non-stretching grid. 2. How do I control Upper...

    How to run WRF with one initial time data?

    Hi, all 1、I wrote a basic initial field environment file based on the solution of the equatorial wave equation. I positioned its initial time at 2021-01-01_00 and converted it into a file in met*nc format. 2、I want to Run it for 90 days to see if it can produce some weather-scale fluctuations...

    idealised cases - implications of 1d base state

    Hello, I would like to run a WRF idealised simulation prescribing a 3D wind field. I have modified module_initialize_ideal.F accordingly, following the example of the 'em_b_wave 'case for which a 2D wind field is prescribed, and got my wrfinput file ready to go. However, I don't quite...

    How can I run wrf-les with a generated wrfinput

    I have generated an analysis after the EnKF and now I want to link it as wrfinput to run wrf-les, but a segment fault always happens when the run just begins. I'm sure my disk and memory are sufficient and time_step is suitable. How can I run the wrf-les with this file? I wonder whether I can...

    when compiling the ideal model in em_ Les, how to define the mminlu of land use dataset as "MODI-RUC"

    Dear all: when compiling the ideal model in em_ Les,I chose sf_ Surface_ Phycics=2, and then an error is reported as: -------------- FATAL CALLED --------------- FATAL CALLED FROM FILE: <stdin> LINE: 1959 Land Use Dataset '' not found in VEGPARM.TBL. So I'm confused about when compiling...

    Idealized Tropical Cyclone's SST

    Hello, I ran some cases with the Idealized TC with various values of SST (by modifying the 'module_initialize_tropical_cyclone.F'). The values of 10m max windspeed tend to converge after 15 days. I wanted to know the effects of changing sea surface temperature on TC. Are the values I modified...

    change SMOIS and TSLB in ideal test

    Hi, WRF support: The fact that SMOIS and TSLB in the wrfout became 0 over the ocean after I added some land in an ideal experiment seems unreasonable to me. Could you please explain the reason for this? Attached is a figure. The second question: I would like to know the most effective way to...

    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...

    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...
