wrf physics

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...

I attempted to run WRFV4.5.1 using the attached namelist.wps and namelist.input. It appears that the model ran successfully; however, there are some lines in rsl.out.000* that I'm unsure about. I would be grateful if someone could help me understand these lines. Are they important? Should I...

Dear community, To the best of my knowledge, I think the SLUCM considers anthropogenic heat by giving a heat source term to each urban category(e.g., 20W/m2 for subruban category). and the BEP/BEM calculate the heat emission from air conditioner (AC). My questions are: 1. Does BEP/BEM...

Dear Community, I have ran a same simulation successfully. When I modified the land cover data slightly (mainly Urban parameters for urban canopy model) and rerun the same simulation, it crashed after almost one month of simulation and shows as follows: ERRENG = 1.368042 at i,j...

Can someone run WRF-V4.5 with the Thompson scheme (mp_physics=38)？ It will crash when i setup mp_physics=38.

Hello, I am working with the WRF version 4.4.2 and noticed something odd in the file module_physics_init.F under the phys directory. -------------------------------------- CASE (LSMSCHEME) IF(TRIM(mminlu) .EQ. 'NLCD40')THEN CALL wrf_message('Using NLCD40 for Noah, redefine urban categories ')...

Hi WRF community, I have a simulation that I have always been able to do restart runs for, it consisted of 2 scenarios: Control and Irrigation. The irrigation run only utilizes existing irrigation options in the WRF namelist. I have managed to do restart runs for both scenarios before using...

The variable radt is a little confusing in the namelist description above. So If I have a domain that is 9-3-1km should radt be set for 9 across all domains or 9-3-1 for each of it's domains?

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...

Dear community. I trying to run a WRF simulation with sf_urban_physics enabled. However the model crashes around end of June for two different years (2021 and 2022): forrtl: severe (408): fort: (3): Subscript #1 of the array KA_MN2O has value -2147483647 which is less than the lower bound of 1...

I am currently using the version 4.1.2 and trying to use time-varing ocean currents imported from the coupled ocean model. Also, the time-varying sea ice information has been imported from the coupled sea-ice model. After examining the code, the surface currents are removed from the lowest...
