wrf physics

I'm running a model with WRF version 4.5.2, but it can't proceed any further due to an error. What is unusual is that if I set the domain to nesting d02, it runs normally, but if I set it to d01, the model does not run. Also, even when set to one domain, it performs well if I change the...

This might not be a very specific question, but does anybody know if it is possible to couple WRF-LES with a land model (e.g., CLM 5) for high-resolution simulation (grid resolution a few meters or so), so that a canopy could be explicitly modeled over several vertical layers (modeling energy...

Hi I'm trying to set the prec_acc_dt = 60 (mins) on my namelist but when I get the results prec_acc_c and prec_acc_nc variables are zero. I checked the accumulated rain values and RAINC is zero, RAINNC gives precipitation I cannot find the mistake on my namelist, could you help me? Thanks

Hello, I am modeling WRF-Hydro for the California region of the United States and running the command . /wrf_hydro.exe with the following error, the detailed log file is attached, enter the file can be downloaded by clicking the download link, can you help me to see what the problem is, and how...

I want to study sea-land breeze in different thermodynamic case. case 1 : sea-land temperature difference is 5 degree C. case 2 : sea-land temperature difference is 10 degree C. it isn't correctly '5' or '10' degree C, but I want to see the difference of wind, snow in different sea-land breeze...

cudt: 0 minutes between cumulus physics calls; set to 0 (call every time step) when using all cu_physics options except Kain-Fritsch; set all domains to the same value max_dom cu_physics = 11, 0, ! Cumulus parameterization...

Dear friends, I missed an error when I run the ./wrf.exe in WRF-noahmp. here touched my namelist.input and some input data. when I change the time_step from 180 to 120 to 90, it always said the same error in the different time, such as 2020-07-03, 2020-07-14, 2020-09-18. **WARNING** Time in...

Hi all, I'm currently trying to figure out how to impose two variables (HFX and QFX) from a control run to a new run. For my new run, I have located in the module_surface_driver file where to edit the values (line 3028 as the last call under the CASE LSM just before the CASE NOAHMP is invoked)...

Hello everyone, I am trying to run WRF solar (WRF version 4.5) taking into account both direct effects of aerosols thanks to CAMS AOD forecasts and indirect ones using water- and ice-friendly aerosols climatology. I have difficulty activating Thompson aerosol-aware parametrization. Everything...

Hi everyone, This error is similar to those reported in several other cases over the past year ('WARNING, THE URBAN FRACTION WILL BE READ FROM URBPARM.TBL' occurred., Problems running Urban UCM and WUDAPT LCZ, cglc-modis-lcz_100m dataset " WARNING, THE URBAN FRACTION WILL BE READ FROM...

Good afternoon, I am looking for an example namelist to run the wrf over the united states. I know there is a namelist with several configuration options listed in the wrf folder but it has EVERY option available. I only need one for basic set up. Is there a namelist that is good for...

Hello, I am having a noise istarting from the beginning of the simulation while using WFP , i have no idea how to resolve it, i tried all the physics i have ! Can any one please help me how to get rid of it, it is creating this disruptancy in my child domain. the plot shown below is a...

Hi, I am using WRF4.3.3 along with WUDAPAT LCZ. When i use sf_surface_physics= 0 the model runs smoothly. But when I use sf_surface_physics= 3 to activate BEM/BEP the model gives me this error: mpirun noticed that process rank 3 with PID 0 on node exited on signal 6 (Aborted).

So, in order to run hectometer scale simulations, I used a range of options (km_opt=2, 4, 5 or the Shin-Hong scheme). I use a 9-3-1-0.2 km nested domains and this is what I used thus far: km_opt=2 or 4 with YSU scheme on the D01-03 km_opt=5 on all domains (3D-TKE scheme) Shin-Hong scheme on all...

Dear all, I ran two simulations with different radiation scheme, when ra_sw_physics=4 and ra_lw_physics = 4 ,the PBLH are normal, but when the ra_sw_physics= 0 and ra_lw_physics = 0,I can't found PBLH by ncview.I can't resolve it and here's my namelist_input. Yours, TARO

Dear seniors, I am a beginner, I want to know if I want to imitate the performance of typhoons (or tropical whirlwinds). How should I act? In fact, I have developed a tropical whirlwind simulation in the ideal mode. But because I don't know how to set the position of a whirlwind, I haven't...

We use WRF version 4.5.2 for urban climate studies. Registory.EM_COMMON has been modified to output variables related to urban areas. Some skin temperature results, such as TR_URB2D (urban roof skin temperature), TB_URB2D (urban wall skin temperature), and TG_URB2D (urban road skin...

Dear all，I was trying to run a simulation. I am getting error： Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0 0x7FE34E0F76D7 #1 0x7FE34E0F7D1E #2 0x7FE34D5F327F #3 0x1E63E37 in taugb3.6165 at module_ra_rrtmg_lw.f90:? #4...

Hello, When I run WRF, I get 24 hours of output for my 3 day simulation before getting errors. I imagine this is due to a problem with the physics or dynamics parameters I have set in the namelist, but am not spotting the issue. Namelist and rsl* are included below. Thanks!

I'm looking for an ensemble technique, and I remember using it in other numerical models and I think it was also used in WRF, but I'd like to know the specific method. This is a method of using the effects of multiple physics processes in one experiment. Once dynamics is performed, it then...
