Aerospace Science and Technology "Meteorological Scout" for the first time appeared at the service trade meeting

On August 31, the China International Trade Service Fair opened in Beijing in 2022. The 23 meteorological products of the Second Hospital of China Aerospace Science and Technology participated in the first exhibition. In the meteorological and global service trade exhibitions, the latest technical achievements and comprehensive solutions in the field of disaster prevention and mitigation and civil aviation and people's livelihood were demonstrated.

In recent years, extreme weather has appeared frequently, and rapid meteorological information detection is beneficial to provide data support for disaster prevention and reduction. Compared with the conventional Dopler weather radar scanning for one week, it takes 6 minutes. The 23 X -band phased array weather radar only takes 1 minute and half to complete the scan, which allows it to capture the changes in the weather elements quickly. Except for fast speed, the radar phase -control array antenna is like the compound eye high -precision observation of the weather elements of the dragonfly. Any small rapid changes cannot escape its observation. This product is mainly used for precipitation observation, which can realize real -time monitoring of catastrophe, hail, and thunderstorms, and provide data support for disaster prevention and reduction.

Since July, droughts have occurred in many regions of Sichuan. In order to alleviate high temperature and drought, the meteorological department has seized the weather conditions to carry out artificially affecting weather rainfall operations in a timely manner. The evaporation of the water rose to the cloud, the cloud condensation landed as the rain, and the rainfall could not be separated from the situation of the cloud. The millimeter wave test cloud radar is currently the most effective equipment to achieve cloud refinement detection. In 2007, 23 developed the first domestic double -partial vibration measurement cloud radar to "do CT" to the cloud. Movement speed, etc., help comprehensive detection and analysis of weather such as cloud, rain, snow, etc., monitor real -time monitoring of low -energy visibility weather such as low clouds, snowfall, and fog, provide early warning, and provide effective data on the weather.

Based on this, the millimeter -wave test cloud radar series products have a 40%share in the domestic market. In the Beijing Winter Olympics in 2022, the measuring cloud radar performed low visibility weather monitoring such as snowfall to provide data services for the weather protection of the event.

At the exhibition site, the mushroom -like millimeter wave test cloud instrument caused the audience to watch. It was a star product. Both Shanghai World Expo Station and Antarctic Scientific Survey Ship used it. It can detect cloud volume and cloud -like information from the ground to 15 kilometers from the ground, to monitor meteorological disasters in key areas where the weather is frequent, and conduct high -resolution, high -precision real -time monitoring and early warning of the flow weather in local areas and early warning of early warning. Provide accurate weather information for artificial rainfall operations.

Climate change not only has a huge impact on the lives of the people, but also brings a series of butterfly effects on various industries.

Climate changes have caused the air temperature and density, the aircraft takes off, and the air weather service at the airport terminal has encountered new challenges due to climate change. In order to cope with the impact of possible aviation dangerous weather on the safe operation of the airport, 23 sand tables showed a safety early warning solution for civil aviation airports. Form comprehensive detection data for different meteorological elements.

There is a civil aviation airport runway model in the sandbox. Near the runway is the ground automatic observation system, windline radar, laser tuning radar, weather radar and other products. Through these equipment, coordinated observations are carried out at the airport to achieve low -altitude wind cuts and low visibility at low energy visibility. , Strong real -time detection and warning of flow weather to improve the ability of the airport to deal with complex weather. The products or systems in the system solution are applied to 22 civil aviation airports including Beijing Daxing Airport. (Global Times reporter Fan Wei correspondent Chen Jiajia)
