wrf.exe

Hello! I'm writing this question after @kwerner prompted me to open a new thread for my issue (here). I'm new at this forum but have some experience with the model which was always supervised up until now. Currently, I am trying to run a simulation in order to later use WRFDA. All the...

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...

Hi there！ I got a question when executing real.exe. I used three levels of nesting. Each nested area has 8 met.em files with a time resolution of 3h. I found that after deleting some of the met.em files in d02 and d03, the real.exe program can still run normally, and eventually SUCCESS...

Hi all, I met this problem while runninf Wrfv4.5: [comput1:4365 :0:4365] Caught signal 11 (Segmentation fault: address not mapped to object at address 0xfffffffe07e33640) ==== backtrace (tid: 4365) ==== 0 0x000000000004d455 ucs_debug_print_backtrace() ???:0 1 0x0000000002d4b161...

Hi, guys, I hope I can get your help. At present, I have successfully completed the operation of VPRMpreproc program, and got seven related parameters, such as LSWI, LSWI_max/min, EVI, EVI_max/min and vegetation_fraction_map. But these seven parameters are divided into seven files. So, my...

Dear WRF Team, I hope this email finds you well. My name is Saikrishna, and I am currently engaged in the simulation of heavy rainfall events over India using the WRF model. My objective is to analyze both local-scale and large-scale features during these events. In my endeavor, I have...

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 am running a simulation in WRFV4.2.1. I have successfully run WPS and real.exe. When I run wrf.exe I get this error "Possibly missing file for = auxinput6". Which is for bio emissions I think. I get this error even when I have not opted for chem. I have attached my namelist.input and...

Hello, I am currently working on a case study focusing on a MGW event spanning March 6th to 7th, 2008, and I am running into a few challenges with the simulation slowness that I am hoping to get some advice on. For this study, I have configured my simulation with 3 nested domains, using a 1:4:4...

Hello, I have already successfully executed real. In running wrf I receive the following error: open_hist_w : error opening /glade/derecho/scratch/$USER/spillover_200612/wrfout_d03_2006-12-13_00:00:00 for writing. That particular folder is empty. I have exhausted my troubleshooting checklist...

Good morning everyone, I am thrilled to announce a secret project that Jiri Richter and I have been working on to enhance the NSF NCAR - The National Center for Atmospheric Research's Weather Research and Forecasting Model #WRF. The WRF Domain Wizard, a cornerstone tool for meteorologists and...

Hello, I am using WRF version 3.9. After completion of WPS and real.exe, I tried to run wrf.exe and got the error -"No physics suite selected. Physics options will be used directly from the namelist". But my real.exe was successful as the files wrfbdy_d01 and...

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...

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 all, I am currently running WRF simulations with the goal of resolving rather short wavelength (high-frequency) wave motions in the lee of a mountain range (wavelength of several km and period of 1-10 min); in the past these motions were attributed to KH instability between the...

ERROR reading namelist namelist_quilt I don't know what went wrong. Real.exe succeeded.

Hello： I am trying to use the 'pressure level output' option in WRF4.5.2 To save U, V, T at some pressure levels.But according to my namelist output, the file contains variables such as U10, V10, T2, etc., and does not include variables such as U, V, T, dew point temperature, etc. My input...

Hello everyone, I am trying to run the Fire module of WRF 4.2.2 using real data (GFS 0.25), and I get the the following error message after running wrf.exe: Timing for processing lateral boundary for domain 1: 0.02313 elapsed seconds Tile Strategy is not specified. Assuming 1D-Y WRF...

Hello everyone, I have converted the local climate zone (LCZ) of wudapt to geogrid using the w2w package and divided it into 41 categories. After successfully running real.exe, the error occurred while running wrf.exe. I checked that the NUM_LAND_CAT in the file generated by metgrid was already...

Hello everyone, I'm running some simulations with WRF version 4.5.1 coupled with sf_urban_physics = 2 and bl_pbl_physics = 8 for three one-way nested domains for a month. Initially, I defined the eta levels with auto_levels_opt = 2, dzbot = 35, dzstretch_s = 1.3, and dzstretch_u = 1.1. This way...
