Meteorological data are essential for weather forecast and climate prediction with complex formats. In view of the lack of convenient and general format conversion processing tools in meteorological data application research, a general meteorological data format conversion tool is designed and developed with python, which implements the algorithm factory and calls the third-party meteorological data processing library to integrate the interpretation, analysis and format conversion of meteorological data. It provides the command-line and visual application tool for application scenarios. The tool has been published on the website of the Beijing high-performance computer application centre and deployed in the pilot support environment of the numerical prediction model.
