Extended data:

Meteorological observation records and meteorological information compiled on this basis not only provide daily data for weather forecasting, but also process them into climatic data after long-term accumulation and statistics, providing important data for planning, design and research in agriculture, forestry, industry, transportation, military affairs, hydrology, medical care and environmental protection.

The disastrous weather monitoring network, which is composed of atmospheric remote sensing detection and high-speed communication transmission technology, has been able to directly issue early warnings of severe weather such as tornadoes, strong storms and typhoons to users in a very timely manner. The development of atmospheric detection technology provides conditions for reducing or avoiding losses caused by natural disasters.
