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.
。北京时间1月14日消息,天文学家收到了许多来自遥远星系的神秘信号。当这些被称为快速射电爆发(FRB)的信号到达地球望远镜时,它们会显示持续数毫秒的明亮爆发,然后消失。

二 | 在过去的十年里,天文学家已经检测到数十个快速的无线电脉冲信号,新的信号正在出现,其中包括一个罕见的重复信号。我们不清楚这些信号是什么,它们来自哪里。目前,科学家主要有以下五种猜测。当快旋中子星爆炸并死亡时,它们的最终结果可能是快旋中子星。天文学家相信,强磁场中的中子星可能会产生异常快的无线电波爆发信号。”加拿大不列颠哥伦比亚大学的天体物理学家IngridStairs说:“像中子星这样的物体确实是很好的信号源。

三 | ”但是我们不知道这高能无线爆炸是通过什么物理过程产生的,两颗中子星合并两颗中子星相互碰撞是产生快速无线风暴的另一种可能性。加拿大麦吉尔大学的天文学家Shriharsh Tendulkar说,这是一个主流的假设,但只适用于只检测一次的宇宙信号,因为中子星在碰撞中被摧毁。_强磁场中的中子星(图像)可能会产生奇怪的快速无线电脉冲信号。

四 | ”这是一个毁灭性的事件,不适合重复的快速无线电爆发,”尖利刺耳的tendulkar说。在过去的十年里,望远镜捕捉到的大多数快速的无线电风暴在一次出现后就消失了。然而,天文学家发现了两个反复出现的神秘信号,需要用其他理论来解释。当一颗快速旋转的中子星坍缩并形成一个黑洞时,闪电被称为“闪电”。快速的无线电风暴可能起源于闪电,但就像中子星合并一样,它们也是恒星毁灭的过程,因此不可能产生重复的信号。黑洞可能是快速无线电风暴的起源。许多假设都提到了黑洞。人们认为,快速的无线风暴可能来自中子星掉入黑洞,或来自黑洞坍塌,甚至来自暗物质与黑洞的碰撞。虽然许多天文学家认为快速的无线电风暴是完全自然的产物,但一些人推测它们可能是外星生命活动的证据。根据Steels博士的说法,射电望远镜能够探测到来自宇宙的快速射电风暴的可能性非常小。”它们的出现遍布整个天空,在不同的距离,所以它一定与许多不同的星系有关,”她说。如果许多不同的外星文明决定以同样的方式发送同样的信号,那将是令人惊讶的。似乎不太可能。
