WRF安装教程

### WRF Model Installation Guide #### Preparation of Environment For setting up Weather Research and Forecasting (WRF) Large Eddy Simulation (LES), it is essential to have proper guidance and resources as this setup can be challenging for beginners[^1]. Ensuring that all prerequisites are met before starting the installation will streamline the entire process. #### Installing NetCDF Libraries One critical step involves installing the necessary libraries such as NetCDF. Instructions provided by UCAR detail how one should proceed with configuring these dependencies correctly. For instance, following specific guidelines ensures compatibility between different components required during compilation time[^2]. ```bash # Example command from netCDF documentation ./configure --prefix=/opt/netcdf --enable-shared --disable-dap make && make install ``` #### Extracting and Configuring WRF Source Code After obtaining the source code tarball through an official link or repository, extract its contents under `Build_WRF`. Navigate into the extracted directory where further configuration takes place via executing `./configure` script within the top-level folder containing WRF files[^3]: ```bash tar -xvf v4.5.1.TAR.gz # Replace version number accordingly cd WRF/ ./configure # Choose appropriate options based on system architecture ``` Select option **35** when prompted about compiling type followed by accepting default value '1' unless there’s a particular reason not to do so. This selection prepares environment variables needed later while building executables. #### Compilation Process Once configured successfully, initiate the build procedure using: ```bash ./compile em_real >& log.compile & ``` This asynchronous operation logs output messages inside `log.compile`, allowing monitoring progress without blocking terminal interaction until completion. #### Verifying Dependencies Like Flex/Yacc Versions Before encountering issues related to tools like KPP due to mismatched versions of utilities used internally—such as lexers (`flex`) and parser generators (`yacc`)—verify their presence along with correct editions installed globally accessible paths listed below[^5]: ```bash which flex # Should point towards valid executable path e.g., /usr/local/flex/bin/flex which yacc # Similarly check for yacc location i.e., /usr/local/yacc/yacc ``` If discrepancies arise concerning supported releases mentioned earlier, consider updating them appropriately according to project requirements documented elsewhere online. #### Customizing Physical Parameterizations During Setup Lastly, take advantage of diverse physical schemes offered out-of-the-box by selecting those best suited depending upon research objectives at hand since multiple combinations exist ranging from straightforward yet efficient ones over sophisticated high-cost alternatives down to cutting-edge experimental methods alongside well-established operational configurations already validated against real-world data sets[^4].
