Typhoon Dolphin made landfall in Taizhou, East China's Zhejiang Province, on Sunday afternoon, bringing strong winds up to 42 meters per second and heavy torrential rain to the coastal regions amid a red alert - the highest level in the country's typhoon warning system - issued for it earlier that day.
Authorities in East China's Fujian have relocated nearly 100,000 residents, while coastal provinces are suspending railway services and canceled flights, making an all-out effort to mitigate possible risks.
The NMC maintained orange rainstorm and blue severe convective weather alerts at 6 am on Sunday, forecasting exceptionally heavy rainfall of 250 to 440 millimeters in some areas along the eastern coast of Zhejiang, with heavy to torrential rains expected across Jiangsu, Zhejiang, Shanghai, and Anhui between Sunday morning and Monday morning, China Central Television (CCTV) reported.
In response to the typhoon, China's meteorological authority on Sunday upgraded its emergency response for severe meteorological disasters from Level III to Level II.
Fujian raised the emergency response level for typhoon prevention to Level II at 9 am on Sunday.
As Typhoon Dolphin gathers strength and approaches the coastal areas, Fujian's flood control authority, as of 6 pm on Saturday, deployed a total of 17,800 officials to and relocated 98,900 people from high-risk areas, Xinhua News Agency reported on Saturday.
Fujian has suspended all 115 marine engineering projects and moved 290 construction vessels to safe waters, while 55 passenger ferry routes in affected waters have been halted, chinanews.com reported.
Meanwhile, railway services in the affected regions including Fujian, Zhejiang, Shanghai have also been suspended from Sunday to Monday, according to chinanews.com.
Fujian authorities have urged stronger safety measures for returning vessels, offshore platforms and coastal and island tourism, as well as reinforcement of aquaculture facilities. They also called for timely evacuations from flood- and landslide-prone areas to guard against secondary disasters from the typhoon and heavy rain, chinanews.com reported.
In Zhejiang, Wenzhou city has closed all 85 A-level national tourist attractions, turned away more than 7,400 visitors and evacuated over 1,600, with the relocation effort ongoing, according to CCTV. Next, Wenzhou will next implement a "five suspensions" policy, halting outdoor group activities, classes, work, business operations and transportation.
All fishing vessels at Shitang Fishing Port in Wenling, Zhejiang, have returned to port, with all personnel evacuated ashore and maritime rescue teams on standby. Authorities urged vessels to stay off the sea during the typhoon.
In Shanghai, Pudong and Hongqiao airports operated at reduced capacity on Sunday, with nearly 60 percent of flights canceled. A total of 1,384 flights are scheduled to be canceled including 871 at Pudong and 513 at Hongqiao. Passengers are advised to check with their airlines for the latest updates and adjust travel plans accordingly, according to CCTV.
According to Hu Xiao, meteorological analyst at the NMC, the typhoon has several notable features, including its strong intensity and expansive circulation. The typhoon also has several unusual features. Forming unusually far east, near 180°E, it has traveled more than 7,200 kilometers, making its potential landfall in China a rare event and possibly the easternmost such landfall since 1951. Its 12-day lifespan is also well above the typical seven-to-10-day average, CCTV reported.
According to Ma Jun, director of the Institute of Public and Environmental Affairs, Typhoon Dolphin traveled a long distance and remained at typhoon or severe typhoon strength of its lifespan so far. Despite passing through some areas that were unfavorable to its development, its powerful inner core remained intact, while its extensive cloud system continued to absorb moisture and energy, fueling the potential for torrential rainfall.
The typhoon has remained at sea for more than 260 hours and experienced a rare "three rises and three falls" in intensity. Its unusually long lifespan has allowed it to absorb more moisture and energy, while repeated intensity fluctuations have complicated forecasts of its future track and intensity of wind and rainfall, according to CCTV.
After landfall, Typhoon Dolphin may move slowly, prolonging heavy rainfall and raising the risk of extreme precipitation and related disasters. Its track later in the week remains uncertain as it could interact with the southwest monsoon and cold air from the northwest, potentially broadening and intensifying its impacts, Ma told the Global Times on Sunday.
。 中新网北京8月24日电 (记者 孙自法)宇宙中的小红点究竟是怎样的存在?北京时间8月24日夜间,施普林格·自然旗下专业学术期刊《自然-天文学》在线发表中国学者领衔完成的一篇研究论文认为,小红点可能位于总质量约为太阳10亿倍的小型致密宿主星系中。 这一重要天文发现,为宇宙大爆炸后最初十亿年间小红点等神秘天体的形成提供了新见解。 本项研究关于早期宇宙中小红点的艺术概念图(图片来自研究团队)。施普林格·自然 供图 该论文介绍,宇宙小红点是近年来天文学界关注到的遥远的微小红色天体,其中心可能存在超大质量黑洞。不过,这些小红点的本质和它们光的来源尚不明确。过去的研究在紫外波段发现部分小红点周围存在微弱的延展成分,可能表明存在宿主星系的特征。不过,在光学波段(人眼可见光波段)还鲜有证据可以探测到这些结构成分,而光学波段能更明确地揭示恒星质量。 在本项研究中,论文共同通讯作者、武汉大学教授丁旭恒和湖南师范大学特聘教授杨里岚与同事及国际合作者一起,结合詹姆斯·韦布空间望远镜217个小红点的图像,揭示出在单张影像中无法明确检测到的微弱光学发射(延伸至中心天体之外的光)。 研究团队通过数据建模表明,这些光学发射可能来自正在形成恒星的宿主星系,这些星系平均半径仅210秒差距(约685光年),其紧凑程度约为宇宙历史中相近时期其他相似质量恒星形成星系的2.5倍。 研究团队认为,这些天文学研究发现表明,宇宙小红点并不是孤立的点光源,其周围很可能还存在一个紧凑的宿主星系,这为揭示小红点究竟是什么、又是如何形成的提供了重要线索。 他们也提醒说,本项研究揭示的是小红点这一群体的平均特征。由于其宿主星系发出的光十分微弱,目前在大多数单个小红点中还难以直接探测到。因此,后续研究需要利用更多波段、更深的观测以及更大的样本进一步验证这一发现,并结合光谱信息了解这些宿主星系的性质,进而探索早期宇宙中星系与中心黑洞的共同演化关系。(完) 【编辑:万纪玮】。
