As important data for big data construction, meteorological data has long been integrated into the development of various fields such as politics, economy, and people's livelihood. Disaster warning, ecological civilization construction, the Belt and Road Initiative, and important engineering construction all put forward clear needs for the application of meteorological data. At the same time, the meteorological industry has accumulated massive data; the data volume, data types, data diversity, and data update frequency all have very typical big data characteristics. Developing fusion application technology, fully utilizing the data scale advantage of meteorological departments, realizing the deep application of meteorological data as big data, and exploring and releasing the potential value of meteorological data resources have become an important part of the national big data platform, and are urgent measures for current meteorological business development.
