Chinese cities turn to AI forecasts, smart radar networks to combat extreme weather_我的网站

From AI-powered flood forecasting and digital twins to smart reservoir management, phased-array radar networks and ground-based remote sensing systems, a new generation of high-tech equipment and systems is helping Chinese cities sharpen weather forecasts, improve flood control and make faster, more precise decisions to stay one step ahead of extreme weather.
In Ningbo, East China's Zhejiang Province, where water resources are relatively limited, the calculation of reservoir water release is tricky. If you release too much, the city could find itself short of water after the storm, however if you release too little, the reservoir may struggle to accommodate the floodwater brought by torrential rain. 
Finding that balance is now increasingly a job for AI.
"The balance point has to be continuously analyzed and calculated by the dispatching software," Jiang Yutian, a department director at the Ningbo Water Conservancy & Hydropower Planning and Design Institute Co., Ltd., said, according to CCTV News. 
At the heart of the system is an AI forecasting model that dramatically speeds up calculations.
For the Yongjiang River basin, running a complete flood-control scenario used to take five to 10 minutes. The new model can complete the calculation in just five to 10 seconds, cutting the time required to around one-sixtieth of the previous level.
Using rainfall forecasts and changing water levels, the model refreshes its recommendations every five minutes, calculating how much water should be released, how much can be stored later and how much reservoir capacity will remain when the flood peak arrives. Dispatchers can then adjust water releases in real time, per CCTV's report.
AI is not working alone. A digital-twin dispatching platform allows reservoirs to be managed together rather than individually. Across Ningbo's 16 major medium- and large-sized flood-control reservoirs, operators can see in real time which are approaching capacity and which still have room to take more water.
Hundreds of kilometers inland, another city is using a different technological set of technologies to tackle the same challenge of weather uncertainty.
Nanyang in Central China's Henan Province, which lies in a basin surrounded by mountains on three sides, has experienced widespread heavy rainfall since Monday under the influence of Typhoon Dolphin. Its geography leaves the city exposed to a combination of risks, including urban waterlogging, flooding in small and medium-sized rivers and inundation of farmland.
To track storms more precisely, the Nanyang meteorological authority has deployed a network of four newly installed X-band dual-polarization phased-array radars, together with an S-band dual-polarization radar and a ground-based vertical remote sensing system, according to the China Meteorological Administration.
The equipment allows forecasters to closely track the development and movement of convective clouds and identify areas at risk of intense rainfall earlier.
The city's meteorological authority has also integrated weather data with a citywide video monitoring network covering vulnerable locations such as underpasses, tunnels, river embankments and mountainous villages. This allows forecasters to compare what instruments are detecting with what is actually happening on the ground.
Together, the approaches in Ningbo and Nanyang offer a glimpse of how China's weather-disaster prevention efforts are becoming increasingly digital and intelligent, using faster calculations, denser observations and real-time data to bring greater certainty to decisions made in the face of uncertain weather.

。    AI摘要      厦门“文旅直通车”走进宁夏闽宁镇，开展文化志愿服务与直播推介。活动融合非遗交流与文艺展演，推广精品旅游线路，深化闽宁文旅协作，助力两地民心相通与产业富民。         8月22日至23日，由厦门文旅打造的“文旅直通车”，来到宁夏银川闽宁镇，进行为期两天的文化志愿服务和文旅协作大直播。

B | “直通车”把厦门非遗、艺术歌舞、厦门摄影图片展等带到了西北塞上，也通过直播镜头把闽宁镇的农文旅产品推介给厦门市民和世界游客。未来几天，“文旅直通车”还将走进我市对口帮扶的彭阳县、泾源县，活动将持续至26日。    本次活动是厦门市文旅局落实闽宁对口协作部署的具体举措，也是厦门文化成果走进西北、深化两地民心相通的重要载体。

C | “直通车”文旅融媒体直播采用“厦门演播厅+闽宁镇现场”“实地体验+引客带货”双模式，全景式呈现闽宁协作三十年来的发展成就与两地文化交融的生动图景。

D |     当“直通车”的直播镜头转至宁夏闽宁镇原隆村，第十四批援宁工作队闽宁镇工作组组长李臻卓向观众讲述闽宁镇的命名由来与发展变迁，并重点推介了闽宁镇“葡萄酒+文化旅游”融合发展模式，解读当地如何以葡萄种植为基础延伸出酒庄集群与文旅业态。    闽宁两地非遗、旅游项目的互动交流是“直通车”一大亮点。

E | 厦门非遗代表性传承人与宁夏本土非遗从业者现场展示技艺，交流“非遗”从保护到运用，从文化符号展示到旅游产品开发的经验。“直通车”在直播中，推广了厦旅国际、建发国旅、厦航国旅全新上架的“厦门—银川—固原”精品旅游线路产品，助推两地旅行机构联动拓展客源市场，推动产业协作走深走实。

F |     “直通车”开进闽宁镇期间，两地专业文艺工作者与群众文艺爱好者还同台献艺，开展“闽宁文化大舞台”文艺展演。展演节目既汇集专业院团的精品创作，也包含群众自发参与的文艺项目，充分展现两地群众文化的蓬勃生机与文化交融的民心温度。

G |     市文旅局相关负责人表示，本次“直通车”融合了“文化交流惠民”与“引客协作富民”，是对协作历程的文化回望。厦门将开启两地文旅深化合作的全新模式，以厦门为平台，着力推广宁夏特别是我市对口协作的银川闽宁镇、固原市彭阳县、泾源县旅游新业态和新产品，发挥厦门作为“中国入境游十大城市”的优势，全力做好厦门至宁夏国际游客联程旅游。（厦门日报记者 邬秀君）。
