Introduction
In-depth interpretation of the National Standard of the People's Republic of China GB/T 36109—2018
Background and significance of the formulation of the standard
This standard is formulated to unify the understanding of the scope and boundaries of geographical regions in meteorological monitoring and forecasting services and to improve the accuracy of the use of meteorological information. This standard draws on the research results of geographical divisions for different purposes by predecessors, and combines the differences in climate indicators and the characteristics of administrative regional boundaries, terrain and geographical distribution to form a unified geographical division system for meteorological products.
Overview of geographical divisions of China's meteorological products
| Regional type | Inclusion range |
|---|---|
| Geographic divisions of land meteorological products | It is divided into nine major regions, namely Northwest, North China, Northeast China, Huanghuai, Jianghuai, Jiangnan, Jianghan, South China and Southwest China. |
| Geographic divisions of offshore and surrounding sea areas meteorological products | From north to south, it is divided into 18 offshore sea area forecast areas, including Bohai Sea, Yellow Sea, East China Sea and South China Sea. |

Implementation suggestions and technology evolution analysis
Standardization recommendations: In actual meteorological monitoring and forecasting services, operations should be carried out strictly in accordance with the geographical area scope and boundaries divided by this standard to ensure the accuracy and consistency of meteorological information.
Technical evolution direction: With the changes in meteorological business needs and the development of technology, the geographical zoning method should be further optimized on the basis of existing standards in the future, and new technologies such as big data and artificial intelligence should be combined to improve the accuracy of meteorological forecast services.
