wrf output

Hi,I am trying to simulate typhoon using Vortex Following compile. In many simulated data, there is a clear disconnect between the nested domain and the parent domain.The smoothing option has been enabled, but the effect is not significant. I am confused whether this situation is normal? I have...

I am having problems running WRF-Hydro with NLDAS regridded data (with NAN values replaced) and it shows the following in the diag_hydro.00000 file: t0OutputFlag: 1 read forcing data at 2024-02-01_00:00:00 . /Forcing/2024020101.LDASIN_DOMAIN1 name = "T20" the job is stopped due to the fatal...

Good afternoon Admins, I was wondering if we could make a special tab or list on the WRF user's guide that highlights this specific page. https://www2.mmm.ucar.edu/wrf/users/wrf_users_guide/build/html/output_variables.html I see a lot of users on the forum asking questions about output...

I copied the wrfvar_output file and named it the new wrfiput_d01 file. When I was conducting . /wrf.exe when performing the error: taskid: 0 hostname: server Quilting with 1 groups of 0 I/O tasks. Ntasks in X 1 , ntasks in Y 1 WRF V4.1.5 MODEL...

Hello, I am trying to use mozbc to input dust data to the wrfinput file. This correctly works, and the dust data shows up in the wrfinput file. The problem is that when I run WRF-Chem, the first wrfout file does not contain any dust information. It basically starts the dust variable from...

Hi all! I am using WRF4.2 to simulate a pricipitation process.But the soil moisture is strange.The dark purple area has little change in all simulation period(dedatil in the attachement).However those areas have precipitation variations. The forcing data and SST data i used is NCEP...

Hi All I was wondering if it is possible to get WRF output at specific times. For example, we would like to get outputs at 5 min intervals every 30 minutes. That is outputs at 25,30,35 mins and then 55,60,65 mins and so on. Thanks in advance! fractal

The program got stuck without any error message. No output or log entry appears even after 20 hr. I had to kill the program forcibly. The last few lines of the rsl.error file are: “d01 2024-04-01_00:00:00 calling conv transport for chemical species d01 2024-04-01_00:00:00 calling calc_het_n2o5...

Dear all, I used the MYNN boundary layer scheme, and I noticed that the boundary layer height (PBLH) variable is output in WRF. How is it calculated? Thanks, Bingyao

I am trying to ingest city specific urban canopy parameters that I developed using buildings heights and footprints data. The UCPs I built were: 1) Mean Building Height, 2) Distribution of building heights for 5m bins, 3) Area weighted mean building height, 4) Standard deviation of building...

I have used tslist to output a time series of wind speeds at 10 m height, and when I compare the absolute values of U10 and V10 output in wrfout with the absolute values of the tslist's wind speed in the TS file at the same time, there are many times when the latter wind speed is smaller than...

Hello, I'm currently working on Tahiti Island in French Polynesia (approximately bounded by 154°W / 13°S to 145°W / 22°S) using the Mercator projection. I'm a bit lost. I've been reading about map factors in Skamarok et al., 2008 (working with WRF V3.6) and in the corresponding version of the...

I'll just leave this here, in case someone ever needs it; finding the solution is far from obvious. Because I cannot (yet) access some Python packages to post-process my data, I use NCO instead. However, dealing with time in WRF NetCDF format quickly becomes complicated. Nevertheless, the...

I have been perusing the WRF Registry and have found that it appears WRF is able to output the standard deviation of the wind speed at a 10 meter height in m/s. Does anyone know if WRF is able to output the standard deviation of the wind speed or standard deviation of the vertical velocity at...

Hi, I have run the WRF simulation using Lambert projection. For verification, I have to convert the projection to lat-lon projection and have to mask it according to my shape file for ease of comparison. For this, I have used the rcm2rgrid function in NCL. where I can convert my grid, but...

I am a graduate student and I need to use the WRF model for my thesis entitled "Investigation of Wave Energy Potential on the Black Sea Coast". I will not use it for professional purposes, and I need to perform a simulation in the simplest way possible. I cannot provide more details since I am...

Hi there, I have been trying to find the variable for Specific Humidity (sph) at single level/ pressure levels from the output files. Does it come with any specific parameterization schemes.? Although I tried some combinations and have not been able to find it Thank you so much for your time...

Hi, everybody I use meic2wrf to make wrfchemi, but when I run WRF-ChemV4.5.2, I found that it reports an error Error trying to read metadata, and then it's still running normally after that, but only the information of the weather variable is in the wrfout, and I would like to know what I...

I am currently working with the WRF model and have encountered an intriguing observation regarding the spatial-temporal patterns in the model outputs when using adaptive time step settings. In my simulations, I have noticed significant differences in the spatial-temporal patterns between the...

Hello, I am running WRFv4.4.2 and studying the registry to create only the variables I need in the output. There are numerous files in the ~/WRF/Registry directory, and from what I understand, the files used are different depending on the compilation options (em_real, or ideal, etc.), and there...
