According to the National Space Weather Monitoring and Warning Center, the National Space Weather Monitoring and Warning Center issued a red warning for geomagnetic storms at 9 o'clock on May 11. A geomagnetic storm occurred at 23:00 on May 10, 2024, Beijing time, and the maximum level of the geomagnetic storm reached the level of ultra-geomagnetic storm (Kp=9), indicating that the magnetic storm process will continue in the next 24 hours and may trigger subsequent larger-scale geomagnetic storms.
Affected by this geomagnetic storm, the ionosphere in most parts of the continent will be disturbed to varying degrees. This change will directly affect the accuracy and stability of shortwave communication and navigation positioning, and may lead to communication interruption or navigation error. At the same time, a significant increase in the density of the upper atmosphere will exacerbate the attenuation of low-orbit satellite orbits, posing a threat to satellite operations and satellite communications. In addition, the power grid will also be indirectly affected by geomagnetic storms.
Geomagnetic storm is a short-term geomagnetic disturbance phenomenon caused by the action of high-speed plasma of the solar wind on the Earth's magnetosphere. Geomagnetic storms arise when the high-speed solar wind generated by the solar coronal mass ejection (CME) or co-rotation interaction region (CIR) exchanges energy with the Earth's magnetosphere.
For spacecraft and astronauts in space, geomagnetic storms are undoubtedly a huge challenge. During geomagnetic storms, more space energetic particles will bombard spacecraft and astronauts, posing a serious threat to their life safety and the stable operation of spacecraft. However, for the general public, the effects of geomagnetic storms are not noticeable and do not require special protection. The occurrence of geomagnetic storms is related to the intense activity of the Sun, but it is not directly related to the intensity of ultraviolet radiation.
After the news was published, some interesting discussions arose on the network. Some netizens jokingly said, "It turns out that this is the reason why I can't wake up", in this regard, Liu Yong, a researcher at the National Space Science Center of the Chinese Academy of Sciences and an ambassador for China's aerospace science popularization, said that although high-energy particles interfere with the earth's magnetic field to produce geomagnetic storms, they have little direct impact on human health.
The meteorological detection system industry refers to the field of observation and analysis of the atmospheric environment by using advanced technical equipment and methods. The industry covers a variety of fields such as weather radar, satellite meteorology, meteorological sounding, meteorological ground observation, etc., through which weather changes, climate change, and natural disasters can be monitored in real time. The development of meteorological detection system is not only of great significance for meteorological forecasting and climate research.
At present, China's meteorological detection system industry is growing and developing, and is committed to improving the monitoring capacity of space weather and the construction of early warning systems to cope with the potential impact of natural phenomena such as geomagnetic storms on society.
The layout of China's meteorological satellites
Since the beginning of the 70s of the last century, China has launched a program for the construction of meteorological satellites. As of August 2023, China has successfully launched 21 meteorological satellites, nine of which are in orbit. These satellites include polar-orbiting satellites and geostationary satellites, and China has become the third country after the United States and Russia to have both types of meteorological satellites.
China's operational meteorological satellites Fengyun-2, Fengyun-3 and Fengyun-4 have become members of the global operational meteorological satellite detection system and play an important role in the field of global meteorological detection.
Competitive factions in China's meteorological detection system industry
The mainland meteorological detection system industry is mainly dominated by state-owned enterprises and enterprises with production and operation qualifications such as military industry and aerospace, so the number of enterprises participating in market competition is small. With the trend of multi-dimensional and three-dimensional development of meteorological detection systems driven by a new generation of information technology, enterprises usually only have the ability to undertake part of the subdivided business.
The industry can be divided into four major factions according to the role played by the main business of enterprises in the system. Companies representing weather radars include Narui Radar, Sichuang Electronics and Guorui Technology; Companies representing meteorological satellites include Rayco Defense and Aerospace Ambition; Enterprises representing meteorological software include Zhongke Xingtu and SuperMap Software; Other representative suppliers of meteorological detection equipment include Landun Optoelectronics and Yangtze River Investment.
China's meteorological detection system industry is in a stage of rapid development, and with the increasing impact of climate change on society and economy, the demand for meteorological detection systems is also increasing. With the continuous progress of science and technology, the meteorological detection system has been significantly improved in terms of accuracy, coverage and real-time, providing more reliable data support for meteorological prediction and disaster early warning.
At the same time, with the application of new technologies such as artificial intelligence, big data, and cloud computing, the meteorological detection system is also constantly developing in the direction of intelligence and digitalization, improving the efficiency of data processing and analysis, and providing more possibilities for meteorological prediction and services.
