超级银河大怪兽格斗Climate Gambit: Chinese team develops ‘super brain’ to guide flood precautions using weather, hydraulic and terrain data_我的网站
一 |  Extreme weather is increasingly a global challenge, and the key to addressing climate risks lies in earlier prediction, more precise action and smarter preparedness, with emerging technologies playing a vital role. The Global Times launches the "Climate Gambit" series, exploring how research teams are leveraging cutting-edge technologies, including artificial intelligence, high-performance computing and smart observation systems, to anticipate weather changes, enhance disaster early-warning and strengthen resilience against climate risks. Inside a state key laboratory at Xi'an University of Technology, Northwest China's Shaanxi Province, there is a miniature but complete "water world" which simulated water channels, inland lakes and main rivers to recreate real flood scenarios and test their newly developed GPU Accelerated Surface Water Flow and Transport Model (GAST). Known as a "super brain" for flood control, GAST can complete flood simulations involving more than 3 million computational units within 30 seconds, helping transform flood management from a reaction to emergency into active precautions since "flooding impacts can be predicted even before rainfall arrives." At a time when extreme rainfall and summer flooding have become increasingly frequent, questions such as when the flooding will arrive, which roads may be submerged and when residents should evacuate have become increasingly important. In an exclusive interview with the Global Times, Hou Jingming, a professor at Xi'an University of Technology and the leader of the research team, explained how the GAST model seeks to answer these questions by accurately predicting flood development and identifying vulnerable areas before disasters occur, and how the model helps authorities take preventive measures to reduce casualties and economic losses. AI empowering 'flood drill' The water tank system in the lab was designed to create a controllable, repeatable and observable environment to simulate complex hydrological processes, including river flooding, urban water level changes, lake regulation, drainage pump operations and coordinated flood-control measures. By adjusting variations such as upstream water inflow, rainfall intensity, downstream water levels and drainage conditions, scientists can recreate different flood scenarios. Meanwhile, water levels, flow speeds and other data are collected in real time and displayed on a digital twin platform. "If a rainstorm and corresponding floods are an exam, GAST is like a 'drill,'" Hou said. "It can simulate how floods develop, where water will flow, which areas may be inundated and when river levels may rise, ensuring authorities are well but not overly prepared." To answer the public's concern about "whether my neighborhood will be flooded when heavy rain arrives," the team developed new algorithms for urban surface water flow, including improvements in terrain slope and friction calculations. These breakthroughs have improved simulation accuracy in complex urban environments. Compared with extensive monitoring data, GAST can keep simulation errors of key hydrodynamic factors within 15 percent. This means the model can provide not only general flood trends, but also quantitative information such as water depth, flow speed and inundation areas. Combined with AI technologies, it can identify complex relationships between rainfall, water conditions, flood depth, flow velocity and affected areas, cutting simulations from hours in traditional methods to minutes or even seconds. The faster calculation capability means that once meteorological authorities update forecasts, the model can quickly estimate flood risks in different parts of a city. "The earlier rainfall warnings are issued, the earlier we can identify potential flooding hotspots and high-risk areas," Hou said. "This saves valuable time for evacuation, traffic management and emergency deployment." For smarter disaster response Building an accurate flood prediction model also requires integrating large amounts of urban data other than weather forecasts, including urban terrain, drainage networks and infrastructure information. For example, a model developed for Xi'an incorporates geographic data and drainage system information collected from relevant authorities and field surveys. After receiving rainfall forecasts, the system can quickly calculate possible flooding scenarios, showing when and where waterlogging may occur and highlighting vulnerable roads and areas through visual maps. To demonstrate how the super brain works in case of possible flooding, the laboratory has set a virtual reality area where visitors can experience a simulated urban flooding evacuation in the Xiaozhai area of Xi'an. Wearing VR headsets, participants can see water levels gradually rising and follow emergency instructions to move toward higher ground. The entire technological package has already been applied in real-world flood prevention.  During Typhoon Muifa in 2022, Haishu district in Ningbo, East China's Zhejiang Province, recorded a regional rainfall of 367 millimeters. Using GAST as its core technology, the local flood forecasting platform integrated weather forecasts, AI algorithms and real-time monitoring data to provide rolling three-hour flood risk predictions. Post-event assessments showed that predicted risks at most locations matched actual flooding conditions. The average relative error between predicted and observed maximum water depths was 13 percent. The GAST model was also integrated into a smart rain and flood management platform in Qinhan new city area in Xianyang of Shaanxi, and during a rainstorm warning in July 2022, the platform provided continuous monitoring and forecasts. Based on the results, local authorities shifted from routine inspections to targeted monitoring of flood-prone areas and optimized emergency drainage operations. The model is also being applied to mountain torrent prevention, as it can simulate rapidly changing flows in complex terrain and, combined with machine learning, complete forecasts within seconds. For reservoirs and rivers, it supports sudden and gradual dam-break simulations. In June 2026, the model was presented at a national symposium on flood risk mapping achievements. The technology has since been applied by water resources, emergency management and urban development authorities, expanding from Shaanxi to multiple provinces and regions across China. Looking ahead, the research team is developing a framework that further keeps up with the pace focusing on AI technologies. "Currently, the system operates based on weather forecast, therefore, AI will increase efficiency by using historical cases and real-time monitoring data to correct errors and update forecasts dynamically," Hou said. 。 在勒布朗·詹姆斯辉煌的职业生涯中，转会决定往往牵动整个联盟的格局，而每一次重大抉择背后，都有一位关键人物的身影——他的妻子萨瓦娜·詹姆斯。 近日，萨瓦娜在《Question Everything》播客中罕见地敞开心扉，讲述了与这位篮球巨星相伴二十余年的心路历程。她半开玩笑地透露，如果没有自己的支持与理解，詹姆斯或许根本不会在生涯暮年选择加盟费城76人。这番话揭开了体育史上最受瞩目转会决策背后，一段关于家庭、信任与共同成长的隐秘故事。 面对“爱上一个在全世界面前光芒万丈、回家却判若两人的名人有多难”这一问题时，萨瓦娜坦言这确实不容易，但詹姆斯身上一种罕见的品质让一切变得简单：惊人的一致性。
二 | “勒布朗在这一点上做得非常好，他始终如一，”萨瓦娜说，“这让我们之间的相处变得轻松。”她进一步解释，詹姆斯在球场上展现出的本色、力量感和鼓舞人心的能力，回到家后并非消失，而是转化为丈夫和父亲角色中的另一种能量——方向变了，但内核始终相同。这种表里如一，让萨瓦娜无需在公众形象与私人生活之间反复调适，也让她在镁光灯照不到的角落里，依然能够触摸到那个真实的人。 萨瓦娜今年39岁，与詹姆斯相遇时才16岁，这意味着她认识他的时间已经超过了人生的一半。他们从俄亥俄州阿克伦的高中恋情起步，2013年9月步入婚姻殿堂，至今已携手走过十一年婚姻生活。在当今体育圈和娱乐圈夫妻分道扬镳屡见不鲜的背景下，他们的持久关系本身就是一种稀缺的证明。
三 | 萨瓦娜将这一切归功于两人始终没有忘记自己是谁——“我们彻头彻尾都是阿克伦人，这是我们的全部。
四 | ”这种来自根脉的朴素认知，让他们在名利场中守住了最普通也最珍贵的东西。 当被问及对其他运动员伴侣的建议时，萨瓦娜给出了一个看似简单却极具分量的忠告：“像关注你的伴侣一样关注你自己。”她坦承这正是自己年轻时没能做到、如今十分后悔的一点。在詹姆斯征战NBA的漫长岁月里，她一度在各种琐事、孩子和光鲜表象中迷失了自我。如今她明白，唯有保持对自己的关注，保持对最初那份关系的真诚，才能真正支持伴侣走向更远的地方。“在你们共同成长的过程中互相扶持，但永远不要丢掉自己。”这或许是萨瓦娜用二十年时光换来的人生智慧。 维持一段长达二十余年的亲密关系，特别是在体育巨星常年征战、聚少离多的现实下，从来不是一件容易的事。萨瓦娜承认，这比外界想象的要艰难得多。“它被呈现成某种梦幻的样子，那是人们渴望看到的。但回到现实生活，面对真实的情感、真正的成长和种种干扰时，事情就变得棘手了。
五 | ”她说，需要全身心投入你所爱的那个人，并拥有极深的理解力和耐心——理解他来自哪里，理解当下的处境，也理解未来可能发生的一切。 詹姆斯本人从不避讳表达对妻子的感激。
六 | 他曾公开表示，没有萨瓦娜，他不可能取得今天的成就。正是萨瓦娜守住了家庭的大本营，才让他能够心无旁骛地继续追逐历史最佳的地位，甚至推迟了退役时间。从某种意义上说，萨瓦娜是唯一能“防住”詹姆斯的人——她的支持像一道稳固的防线，让他可以放心向前冲；她的意见也往往成为他人生重大决策的最终参照。正如坊间流传的那句话：得贤妻者，得天下。詹姆斯与萨瓦娜的故事，用二十余年的相守印证了这古老箴言的现代版本。 Current article:http://ddl41te.cheshenzhuaduanza.buzz/list_a4fagx0/ilo.html Published on:05:31:39 |
