The 31st World University Summer Games (hereinafter referred to as the Chengdu Universiade) is about to 7 month 28 The day will kick off, and all preparations have entered the final sprint stage. A meteorological service team from Zhuhai, Guangdong, under the leadership of the Chengdu Universiade Meteorological Observatory, is fighting on the front line of meteorological guarantee services for the "Chengdu Universiade" with refined technology and services, making every effort to ensure the successful holding of the event.

2023 year 7 month 24 afternoon 17 From 18 o'clock to 33.3mm o'clock, on the eve of the opening ceremony of the Universiade, a local heavy rainfall weather process occurred in the western part of Chengdu. The center of the heavy rainfall was mainly in Dayi County, with the maximum hourly cumulative rainfall recorded by the automatic station X The data results detected by the band dual-polarization active phased array weather radar deployed in this area are consistent, without any discrepancy. This high-precision detection result has given the Naruida radar team stationed on the front line of meteorological guarantee services for the Chengdu Universiade great confidence. After several months of careful debugging and preparation, they are more looking forward to the arrival of the Chengdu Universiade than ever before!

Naruida radar was invited to provide meteorological guarantee services for the Chengdu Universiade

Weather is an unstable factor for the Universiade. Chengdu is located in Southwest China, with complex topography and landforms. It is not only the first area affected by important strong weather systems such as the eastward movement of the Tibetan Plateau vortex, but also an important area for the generation, development, and demise of the Southwest vortex. It is also a high-incidence area for highly disastrous small- and medium-scale weather systems such as hail, thunderstorms, strong winds, and local short-duration heavy rainfall.

In order to ensure the smooth holding of the Universiade, the meteorological department has set up a comprehensive network, keeping a close watch on the changes in the weather in Chengdu. Among them, the independently developed X band dual-polarization phased array weather radar is an important "tool" for meteorological guarantee of the Universiade.

It is understood that X band dual-polarization phased array weather radar adopts a radar technology system that combines polarization and phased array technology, with ultra-high spatiotemporal resolution detection capabilities. It can complete 60 seconds 60km detection distance and 68 layers of elevation angle volume scan detection, and the time resolution is improved by 6 times compared to traditional radar; the spatial resolution reaches 30 meters, which is improved by 64 times compared to traditional radar. At the same time, X band dual-polarization phased array weather radar can also realize hydrometeor phase detection, accurate quantitative rainfall estimation, three-dimensional structure detection, and three-dimensional wind field detection, which can provide richer and more accurate products for major event meteorological guarantee than traditional weather radar, greatly improving the ability of meteorological departments to respond to meteorological guarantee for major events.

Naruida radar's X band dual-polarization phased array weather radar has successfully completed meteorological guarantees for many major events, including the opening ceremony of the Hong Kong-Zhuhai-Macau Bridge in Zhuhai, the 14th National Games in Xi'an, and the Guangzhou crossing the Pearl River event, and has received high praise from users. At the Chengdu Universiade, Naruida radar continues to forge ahead with its original aspiration, continuing to be a weather watchman and providing escort services for national events.

In order to ensure the smooth holding of the Universiade, 2021 year, Chengdu Meteorological Bureau and Naruida Radar gradually promoted the construction of Chengdu X band dual-polarization phased array weather radar network. So far, it has completed the construction of 8 radars in Pengzhou, Chongzhou, Dayi, Xindu, Tianfu, Jianyang, Shuangliu, and Qionglai, covering the entire Chengdu area. 8 radars have been built, and the radar network covers the entire Chengdu area.

In addition to radar production and R&D, Naruida Radar actively promotes innovation in radar application software, and has developed software applications such as a severe convective weather monitoring and warning system, a multi-band radar data fusion system, and a refined short-term weather forecasting and warning system, which can provide Yonggu with refined and intelligent services for the entire process of meteorological monitoring, meteorological warning, meteorological forecasting, and meteorological services.

Naruida Radar's integrated phased array radar application platform can provide customers with a variety of radar meteorological application services.

Naruida Radar's severe convective weather monitoring and warning system can realize three-dimensional visualization and analysis of phased array radar products, and can also realize intelligent early warning of severe convective weather.

The multi-band radar data fusion and warning system can support the fusion and display of data from different band radars, giving full play to the advantages of different band radars, and has the ability to monitor and warn on a large scale and monitor locally in detail.

The refined short-term meteorological forecasting and warning system can realize 0-6 hours of minute-level refined grid forecasting, providing accurate quantitative forecasting products for event meteorological services.

" X band dual-polarization weather radar is an active atmospheric remote sensing detection device, which has advantages over other monitoring devices in dealing with sudden and real-time weather systems, especially its fast scanning speed, high detection accuracy, real-time observation unaffected by complex terrain and harsh environments, and all-weather 24 Its features, such as continuous real-time monitoring around the clock, make it an indispensable part of the Chengdu Universiade meteorological service support system." said a staff member of the Chengdu Universiade Meteorological Station.

For the Chengdu Universiade meteorological support service, Naruida radar has made thorough deployments in product compliance and technical support.

6 Month, the Naruida radar meteorological support team held a X training session on dual-polarization phased array radar products and applications, ensuring that the Universiade meteorological support personnel can skillfully operate the radar application software and understand the theory and ideas of using phased array radar for weather analysis.

On the eve of the Universiade, the Naruida radar meteorological support service team conducted inspections and maintenance of the radar to ensure the stable operation of the radar during the Universiade.

During the Chengdu Universiade, the Naruida radar dispatched a technical team to Chengdu to provide on-site support and technical guidance, responding to user needs at any time and promptly handling emergencies.

According to the latest weather forecast, there will be frequent rainfall during the Universiade, with strong convective weather such as local strong winds and thunderstorms, posing significant challenges to the Universiade meteorological support.

Faced with the challenges, the Naruida radar team does not dare to slack off, but we are not afraid either. We are confident in completing this support task. We wish the Universiade a successful holding, and we hope that people around the world will share this grand event together. The task of observing the sky and measuring the rain is entrusted to us, and we will do our best to support the Chengdu Universiade "Meteorological Guardians".
