wrf output

Hello everyone, I'm trying to run a simulation with data written every 10 minutes (history_interval = 10), but the program skips the statement and writes the results every 60 minutes. What can be caused this? &time_control run_days = 0, run_hours = 36, run_minutes = 0, run_seconds = 0...

Hello everyone, I would like to request a little help with this issue. I am working with WRF v4.4 and v 4.2 in both cases I try to launch a simulation with output data writing every 10 minutes. My understanding is that it should be simple by defining history_interval = 10. But for some reason...

Hello, This is just a general question. I have been simulating typhoon induced precipitation over an area that includes a mountain (bottom figure). This was run at 5x5 km with IC from ERA5. Unfortunately, despite trying all combinations of the cumulus, microphysics, and PBL schemes, the best...

Hi Forum. I am trying to run a wrf model for 6 months using ERA5 re-analysis data. For which I have downloaded the SST and Sea-ice-cover data from Copernicus Climate Data Store | Copernicus Climate Data Store , along with 10m u-component of wind, 10m v-component of wind, 2m dewpoint...

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...

I am calculating downward short wave flux using WRF. I found a variable called SWDOWN among the output variables, and I am curious whether this variable is instantaneous or averaged according to history_interval. I would like to know whether the value of SWDOWN is the instantaneous value of...

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!

I have noticed that there is an issue with the land sea mask that you get from ECMWF is not binary. This is also noted on ECMWF webpage: Land-sea mask in ERA5 and ERA-Interim - Copernicus User Support Forum - ECMWF Confluence Wiki Because the mask is not binary I believe it creates an issue...

Running ERA5 Data from ECMWF Model stops with this error: I tried changing dt to 3*dx and the error went away but the model stopped. I have attached the namelists, rsl files. Any help would be appriciated.

Dear everyone, I met a problem: I am running WRF-chem V3.9, and when I finished running the first real.exe, I found that the generated wrfinput and wrfbdy files are missing a lot of variables, and the aerosol variables that I am concerned about are not there at all (as in Figure 1 in the...

Dear WRF Community, I am working on a July 05-06, 2018, moist convective case, which produces heavy precipitation near the Chicago area. I am using WRFV4.4 to simulate this case. I was able to simulate it successfully, and the results were well comparable with observations (Test1). However...

Hi, WRF support: I'm using a moving grid simulation to study a typhoon (with a nested grid scheme for vortex tracking), and I'm currently facing an issue related to calculating accumulated precipitation during the simulation. I understand that simply adding RAINC and RAINNC is not appropriate...

Looking to see if there are WRF namelist options that need to be enabled to have certain exports in the wrfout file. I am looking for these times of values: 1.) are there any icing or turbulence options at different altitudes from that model? 2.) are there any surface visibility forecast...

dear friends, I encountered two issues when processing wrf output data. first one: when I use the get_pyngl, it told me that RuntimeError: 'pyngl' is not installed or is disabled. but I have install the Nio &Ngl in conda, how to call this program? here is my code. #6.5PyNGL example using a...

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...

Hi, everyone First of all I hope that you are well, continuing with the post I want to ask if there is a way to obtain the relative vorticity as output in the netcdf file from WRF, I have read that the only one that is obtainable is the absolute vorticity. I have been using these formula to...

I am running a case that and always seems to stop at the same time. Things I have tried: 1. Increased number of cores (8 to 16 using mpirun -np 16 ./wrf.exe) 2. Increased ptop (5000 to 3000) 3. Increased e_vert (45 to 50) 4. Decreased time_step (90 to 60) 5, Checked rsl files: I have...

Hi all We are running several experiment by using WRF (v. 4.4.1) coupled with WRF_HYDRO (v. 5.2.0). After several attempts, we understood that it was not possible to run WRF+WRF_HYDRO in hybrid mode (i.e. OpenMP works for WRF but not with WRF_HYDRO). We ran a series of tests to try to improve...

Hello, We are running parallelization tests and using the script referenced here: How many processors should I use to run WRF? to determine the correct number of nodes needed. We are using four domains and using ndown to do so. We have been able to run without issues up to the third domain...

Hello, Sir Normally, WRF generated only 1 wrfout file in each domain. But, I have 3 wfrout files in each domain when ran WRF in 30 August - 3 September 2022 (95 days). Why? I attached namelist.input. Thank you
