Provinces including Zhejiang, Fujian, and Guangdong have activated emergency responses and taken preventive measures as Typhoon Dolphin, the 13th typhoon of the year, approaches, potentially bringing strong winds and heavy rain. Dolphin is about to enter the 48-hour warning zone of China and is expected to make landfall along the coastal areas between Zhejiang Province to northern Fujian Province as a typhoon or severe typhoon between Sunday afternoon and Monday Morning, China Central Television (CCTV) reported on Thursday.
Typhoon activity has intensified recently, with Typhoon Dolphin (No.13 of the year), Typhoon Kujira (No.14), and Typhoon Chan-hom (No.15) forming one after another. Kujira has weakened after making landfall in the Philippines, while Chan-hom is unlikely to affect China. Dolphin maintains strong typhoon intensity despite traveling a long journey, and is expected to approach the coast of East China, bringing strong winds and heavy rain, CCTV reported.
According to Dong Lin, chief forecaster at the National Meteorological Center (NMC), the key characteristics of Typhoon Dolphin are that it formed over distant open waters, has a long lifespan, features a large circulation system, and experiences frequent fluctuations in intensity.
According to Dong, Typhoon Dolphin formed near the International Date Line, something that has never happened since meteorological records began. Then it moved toward China, and is expected to make landfall at an intensity above the tropical storm level. This makes Typhoon Dolphin an exceptionally rare system.
Typhoon Dolphin was located 1,130 kilometers east of East China’s Zhejiang coasts as of 5 pm on Thursday. Large to very large waves are expected in Zhejiang’s coastal waters, and an orange alert for waves is maintained by the National Marine Environmental Forecasting Center, according to China’s Ministry of Natural Resources.
Affected by Typhoon Dolphin, rainfall is expected to begin this weekend. The National Meteorological Center has forecast heavy to torrential rains in parts of central and eastern China from Saturday to Wednesday, followed by further downpours in North China, Inner Mongolia, and southern Northeast China from Wednesday to Friday as the typhoon’s remnants interact with cold air.
China's National Flood Control and Drought Relief Headquarters and the Ministry of Emergency Management activated a Level IV emergency response for Zhejiang and Fujian provinces on Thursday as Typhoon Dolphin was forecast to bring strong winds and heavy rain to East China, according to CCTV.
Affected by Typhoon Dolphin, the Zhejiang Provincial flood control and typhoon prevention headquarters decided to adjust the maritime typhoon emergency response to Level IV at 2 pm on Thursday. Due to strong winds over the sea, 21 water passenger transport routes in Zhoushan, Zhejiang Province, had been suspended as of 3 pm on Thursday, CCTV reported.
Ningbo in Zhejiang had temporarily shut down all coastal attractions and high-risk marine tourism activities by 6 pm on Thursday due to Typhoon Dolphin.
Besides, Fujian activated a Level IV typhoon emergency response at 2 pm on Thursday as Typhoon Dolphin is forecast to enter Fujian’s tropical cyclone warning area on Friday and move closer to the East China coast, CCTV reported.
Fujian has ordered stronger safety management for offshore vessels, marine facilities, and ferry services as Typhoon Dolphin approaches. Coastal areas will reinforce shelter management and prevent people from returning to risky areas, while authorities prepare for heavy rain and wind on land, according to CCTV.
Guangdong Maritime Safety Administration activated a Level IV tropical cyclone response on Wednesday and imposed traffic controls from 6 pm on Thursday on vessels traveling northward through the southern entrance of the Taiwan Straits, CCTV reported.

。“现在好了。”新天科创新能源技术有限公司副总经理许宜菲说，他们积极探索AI在风电运维方面的应用，上线运行“智慧小新”AI智能体，可实现风机故障智能排查和实时预警。目前，“智慧小新”已在公司旗下58座风电场应用，为风电场降本增效、安全运维提供坚实保障。

三 | 巡检作业效率提升18%以上“我在‘云端’修风车。”地处蔚县的新蔚风电场运维人员杨斌，经常爬到百米高空的风机机舱顶部进行检查。近日，新蔚风电场30号风机发生故障。杨斌打开手机端的“智慧小新”，这款大模型提示“变桨闸流晶体管故障”，并推荐了晶体管器件、关联电路等故障排查点。杨斌和同事一起拿着工具前往风机机舱，发现确实是晶体管器件出了问题。

四 | 他们更换了器件，马上解决了问题。“风机是个庞然大物，由叶片、轮毂、齿轮箱、发电机等各种零部件组成。”杨斌说，以往出现故障，他们需要钻入风机内部，在狭窄的机舱内对相关零部件进行逐点排查，费时费力。而现在，“智慧小新”实时掌握每台风机的运行参数，实现风机故障智能分析诊断，提升了他们运维操作的针对性和效率。

五 | “风机运行环境复杂多变，传统人工巡检不仅效率较低，而且在恶劣天气下存在安全风险。”许宜菲说，2020年，面对数字化浪潮，该公司成立大数据中心，搭建风机运行状况智能监测等系统，探索对风电场进行精准运维。

六 | 风电机组厂家、风机型号众多，数据标准不统一，是风电智慧运维面临的挑战。

七 | 许宜菲带着技术团队，对运营的风机品牌进行深入研究分析，统一数据口径、统一运维规范，明确数据采集质量、图像分析算法及故障诊断精度等关键指标。这样，不同品牌的风机有了统一的数据标准。同时，他们接入多个主流大模型，整合公司业务数据、技术资料等数据资产，推动风电运维数智化转型，夯实数字底座。

八 | 2025年11月，具备智能检修、智能问数等模块的“智慧小新”正式上线。在智能检修模块，风机关联数据查询、零部件图纸查看、历史检修记录查询、诊断结果调用等功能应有尽有，助力运维人员及时定位故障点并按标准流程处理。在智能问数模块，基于风电生产运营数据库，可进行风电发电效能、设备健康、运行管理三大类业务32个指标的智能问数、快速回答，实现风机数据高效查询、可视化分析与快速响应。“AI技术带来运维变革，优化了风电场资源配置效率。

九 | ”许宜菲说，目前，“智慧小新”已入库343条高频故障、2.8万余条低频故障，关联超7万条检修记录，为智慧检修提供坚实数据支撑。“智慧小新”上线以来，该公司旗下风电场巡检作业效率较传统人工模式平均提升18%以上。从被动抢修变为主动预防风机智慧检修，已不再是“坏了再修”这么简单。“非计划停机不仅意味着直接的经济损失，还影响到绿电安全稳定供应。”许宜菲说，“智慧小新”专业化预警分析模块，可通过AI算法分析研判风机设备运行状态，在风机处于“亚健康”时及时预警进行处理，避免小故障演变成大问题。前不久，张家口市崇礼区秋林风电场二期122号风机齿轮箱温度高，触发报警。该风电场运维团队即刻响应，对齿轮箱进行检查，快速完成隐患排查与效果验证。“精准预判才能快速反应。
