    Vertical loop index in subroutine "advect_w" when the polar flag is on

    Hi. I'd like to ask about the vertical loop index (for tile, kts, and ktf) in WRF(v3.8.1). In the subroutine advect_w located in dyn/module_advect_em.F, I found that the vertical loop index is kts:ktf as shown below. ``` IF ( config_flags%polar .AND. (j == jds+1) ) THEN DO...

    WRF postProcessing

    Hello,I'm doing a simulation of wrf-les coupling. The CFD tool used is sowfa, and in its examples, there is a case of coupling with wrf, where there is a program to extract data from wrf. But after I changed my filename, nHrs and nPerhrs. Running error : wrfout file does not have z and fc...

    [SOLVED] Segfault for WRF V4.5 with the new hybrid 100-m MODIS-LCZ dataset using SLUCM urban physics

    Hi, I came across segfault for WRF 4.5 using the new modis-lcz dataset under SLUCM urban physics. The segfault always happen at 1 of the 72 cores in Cheyenne. From the error log it seems that the segfault happens during avgflx at solve_em.F. I cannot pinpoint how it happens without any...

    Simulation results change when I only made modification to Registry/Registry.EM_COMMON

    Hello, I met this problem here with WRF-v4.4.1. After I made some modifications to Registry/Registry.EM_COMMON (without changing any part of the other codes) and recompile, the simulation results changes. The modification includes two new variables in "NSSL WRF diagnostics" part, and add an...

    Terminated when running WRF.exe with BEP/BEM, EXIT CODE: 134

    Hello, WRF Team Thank you for your contribution! I am running WRF-Urban with BEP/BEM. However, when running wrf.exe it quits after a few minutes. When I change sf_urban_physics to 2, the model runs fine, but I want to check the energy consumption values, so I have to set sf_urban_physics to 3...

    Strange T2 in WRF v4.4.2 and v4.5 after reinitialization

    Hi all, I am using WRF-Chem v4.4.2 under a triple nested domain (36 km, 6 km, and 1 km) in August 2019. In 6 km and 1km simulations, there is a strange T2 cold bias after several hours of reinitialization. Consequently, simulations crash. I tested different versions of WRF from v4.1.4 to v4.5...

    There is not SFCRNOFF in WRF-Hydro v5.2 or newer

    Hello,WRF-Hydro Team: When I run WRF-Hydro V5.2 or newer version, there is not SFCRNOFF in LDASOUT_DOMAIN2. And the output of WRF-Hydro V5.1.2 is right. What is wrong with the new version ? Thanks!

    Underestimated CLDFRA in 4.4.1 compared to 4.3.1

    Hi All, Significant differences were found in the SWDOWN calculation between WRF-4.3.1 and WRF-4.4.1. Compared with measured radiation data, WRF-4.4.1 shows much worse scores. Similar differences are in CLDFRA: compared to satellite observation WRF-4.4.1 underestimates the values of the...
