As the construction of ecological civilization and the "carbon neutrality" strategy continue to advance, my country's and global climate change and response are the focus of attention of the government, scientific community and business community. Climate is the main driving factor in many fields (ecology, water resources, wind resources, carbon neutrality, etc.). A reasonable understanding of climate change is conducive to explaining the mechanisms and processes of ecological environment changes, and understanding current and future climate change is crucial. It is a prerequisite for ecological, environmental and energy assessment and carbon policy planning, and climate simulation is the most important means to obtain high-precision climate information. Modern ecology, hydrology, new energy and carbon neutral fields require sub-kilometre and higher resolution meteorology. For simulation, the WRF model is the most widely used meteorological model at home and abroad. There are more and more applications using this model for high-precision simulations of even hundreds of meters. On the other hand, the model continues to expand the model module, and now it can realize aerosol and chemical processes (WRF-CHEM), data assimilation (WRF-DA), hydrological processes (WRF-HYDRO), urbanization (URBAN) and other processes The precise simulation has more and more application scope and practical business and scientific research applications. However, this model runs on the Linux platform, and the pre-processing, operation and analysis processes are complex and difficult. In response to the requirements of workers in the fields of ecology, hydrology and environment, the " Full-process WRF high-precision meteorological simulation technology and its application in the field of geosciences" was specially held. Practical Application " .
