    WRF running time limit in HPC system

    Hi Kwerner, I wonder the restart interval time is the actual running time on my system, or the first 24 hours of my simulation period? Best, Stella

    WRF restart setting

    Hi Ming, Could you please kindly explain the differences of "It indicates this is an initial run and the model will output wrfrst files every 24-hr" and " It indicates this is a continuous run (restart run) and the model still will output wrfrst 24-hr intervals"? My WRF output file is hourly...

    WRF running time limit in HPC system

    Hi, If the time limit is 6.5 days in total, should I set restart interval as 9360min to run before stopping. Do I need to repeat running real.exe and wrf.exe again by myself? Or the only thing is to submit my job again? And I would like to confirm whether the restart interval is 1440 or 7200...

    WRF restart setting

    Dear Office, I ran WRF without the settings below: restart = .true., restart_interval = 1440, If I modify this as restart = .false., restart_interval = 1440, during the running period (the wrfout file has not been output for 24 hours), is that ok? I saw your guide at ARW Online Tutorial and...

    urban temperature focusing on heat island

    Dear Office, If I would like to focus on heat island, which temperature parameter should be chosen? T2 or TSK? Best wishes, Stella

    WRF running time limit in HPC system

    Dear Office, Thank you so much for your kind reply. The link shows "To initiate the restart run, edit the namelist.input file, so that your start_* time is set to the restart time (which is the <date> of the restart file). You must also set restart=.true." I would like to know the time when I...

    WRF running time limit in HPC system

    Dear Office, When I run the high-resolution simulation, I found the HPC systems I used have running time limit. Could you please kindly let me know how to handle this issue so that I could run the full job completely. Best regards, Stella

    the type of geographical static data

    Sorry for the confusion. Based on your answer, it seems that WRF can show the elevation of static data? Can WRF remove the elevation for the surface of static data? Best regards, Stella

    higher resolution in model than map

    Dear Colleagues, If I use the higher WRF resolution than that of the geographical static data, can I get more details? For example, 90m model resolution, 500m map resolution. Best regards, Stella

    Distribution of Local Climate Zone Map

    Dear Colleagues, After interpolating the geographical static data generated by WUDAPT, namely the Local Climate Zone map of a city, it divides the urban areas into 17 classifications, how the WRF handles the map that has different fractions for the 17 zones (please note that the map has a...

    the type of geographical static data

    Dear Colleague, I would like to know which model is handled by WRF, Digital Surface Model or Digital Terrain Model (specifically Digital Elevation Model)? Best wishes, Stella

    how WRF handle higher geographical static data

    Dear Colleagues, As we know, the spatial resolution of WRF normally is 1 km. If we use the local climate zone as an urban landscape map, with 30 m spatial resolution, how does WRF handle the map that are with higher resolution than its own? We supposed that WRF may average the 30 m map into 1...

    parent_grid_ratio Setting

    Dear Colleagues, I would like to set parent_grid_ratio as 1:7, 1:9, 1:11, 1:13, 1:15, 1:17, 1:19 and 1:21 to simulate, but the WRFDomainWizard could not generate i_parent_start, j_parent_start, e_we, e_sn automatically. Could you please give any advice? And can WRF simulate too large...

    different maps for simulation results

    Dear Chen, Many thanks for your explanations. I would like to know whether the simulation results will be influenced by different terrestrial data (such as, landuse). Best regards, Stella

    different maps for simulation results

    Dear Chen, Many thanks for your detailed reply. I still have one point to ask: You mentioned "I would expect slight changes in the model results if you run WRF with different map projections". Did you mean that map projections indicate landuse or geographical static data instead of Lambert...

    different maps for simulation results

    Dear Ming, Could you please kindly indicate the duration for short-term simulation? And I would like to know the highest resolution that can be simulated in WRF-Urban. Best, Stella
