Introduction
Interpretation of the National Standard of the People's Republic of China GB/T 35968—2018
Background and Significance of Standard Formulation
Precipitation is an important indicator for meteorological monitoring, and its graphical representation is of great significance in disaster prevention and mitigation, weather forecasting and scientific research. The formulation of GB/T 35968—2018 "Precipitation Graphics Product Specification" fills the gap in the field of domestic precipitation graphics standardization and provides a unified technical standard for the visualization of precipitation.
Comparison of Standard Frameworks
| Standard Dimensions | GB/T 35968—2018 | International Meteorological Standards | Local Standards |
|---|---|---|---|
| Scope of Application | Production and Release of Precipitation Graphics Nationwide | Global Meteorological Monitoring Network | Local Precipitation Monitoring System |
| Core Content | Precipitation Classification, Color Code, Graphic Composition | Global Precipitation Monitoring Standard | Regional Precipitation Classification |
| Technical Requirements | The resolution is not less than 200 dpi, and the color scale is unified | Application of high-resolution satellite data | Regional technical adjustment |
Actual application case: 24-hour rainfall map of a certain area
According to GB/T 28592-2012, 24-hour rainfall is divided into multiple levels, corresponding to different colors and RGB values. For example:
- Light rain (0.1-10mm): RGB values are 161, 241, 141
- Heavy rain (25-50mm): RGB values are 96, 184, 255
- Heavy rain (100-250mm): RGB values are 250, , 250
Implementation recommendations
To ensure the quality and consistency of precipitation graphic products, it is recommended that:
- Use a unified color scale system to avoid visual confusion.
- In arid areas, the classification threshold can be adjusted in combination with local standards.
- Regularly update the graphic product production tools and publishing platform.
