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.

。    Actor Sidharth Malhotra recently opened up about his journey into parenthood with wife Kiara Advani, praising her strength and courage as a new mother. The couple welcomed their daughter in July this year, and Sidharth expressed deep admiration for Kiara while speaking about the beautiful yet challenging experience.     Sidharth Malhotra spoke lovingly about his wife Kiara Advani and how proud he feels watching her step into motherhood. The couple, who tied the knot in February 2023 in an intimate ceremony at Suryagarh Palace in Jaisalmer, welcomed their first child, a daughter, on July 15, 2025. They recently revealed that they have named her Saraayah Malhotra.     Sidharth shared that the name carries a special meaning. He explained that Saraayah is not a Hindi name but a Hebrew one, meaning “Princess of God.” The actor said the name felt personal and unique, just like the experience of becoming parents for the first time.                Speaking about Kiara, Sidharth shared how inspiring it has been to watch her handle pregnancy and motherhood. He said, “Her, my daughter being the superstar, my wife being the superhero, you know, the process of just seeing her through pregnancy and birth is an eye-opening experience for me that, you know, men always talk about courage and grit and, you know, strength, but women actually demonstrate it when they become mothers. I've seen her during pregnancy go through hormonal changes, physical changes, and now she's being a true superhero, taking care of Sarayah, and I'm contributing a little bit with changing diapers and clicking pictures or just trying to keep a happy environment.”     His heartfelt words show his admiration not just for his wife, but for all mothers who go through this journey with strength and patience. Fans praised Sidharth online for speaking openly and warmly about fatherhood.          On the work front, Sidharth was last seen in the romantic comedy Param Sundari, where he played the lead role opposite Janhvi Kapoor. Kiara Advani recently appeared in War 2, starring alongside Hrithik Roshan and Jr. NTR. Next, she will be seen in Toxic: A Fairy Tale for Grown-Ups, which also features Yash, Nayanthara, Tara Sutaria, Huma Qureshi and Rukmini Vasanth.Also Read: Vicky Kaushal & More Salute Soldiers on Kargil Vijay Diwas With Emotional Tributes。
