This year's typhoon season has begun, and the reporter learned that the Central Meteorological Observatory has initially built an artificial intelligence based typhoon monitoring and forecasting system, providing important technical support for improving the intelligence of China's typhoon monitoring and forecasting business and rapidly expanding global tropical cyclone business in multiple sea areas.

Typhoons often experience significant intensity changes within 24 hours, rising by 1 to 2 levels, making typhoon intensity forecasting a global challenge. In response to this, the Central Meteorological Observatory, in collaboration with research institutes, universities, and others, has carried out a series of explorations of artificial intelligence in typhoon monitoring and forecasting. They have established technologies such as typhoon vortex recognition, intelligent determination of typhoon intensity, and rapid enhancement discrimination of typhoons. They have built a typhoon monitoring and forecasting system based on artificial intelligence, which has advantages in processing nonlinear and massive data, helping forecasters add to the accuracy of forecasts.

Zhou Guanbo, Chief Forecaster of the Typhoon and Ocean Meteorological Forecasting Center of the Central Meteorological Observatory: Last year, out of 25 typhoons, 12 of them experienced a rapid strengthening process, which is also relatively rare in history. With the help of artificial intelligence, although the number of typhoons rapidly strengthening is increasing year by year, our level of typhoon intensity prediction has been maintained. In 2022, our 24-hour typhoon intensity forecast error was 3.88 meters per second, exceeding the forecast level for typhoon intensity by the United States and Japan for the first time.

The detection model based on artificial intelligence technology can also intelligently recognize typhoon vortices on infrared cloud images containing a large amount of cloud noise, and quickly locate them. This technology has a recognition rate of nearly 100% for typhoons and above. It is understood that in the next step, the Central Meteorological Observatory will further promote the deep integration of artificial intelligence technology in typhoon monitoring, forecasting, and services, providing innovative technical support for precise monitoring, forecasting, and services of global typhoons.

According to Hong Kong's Wen Wei Po, a bloody knife stabbing case occurred at Hollywood Square in Diamond Hill last Friday. The police arrested a 39 year old man on suspicion of stabbing two young women, one of whom was stabbed over 30 times. The suspect appeared in the Kwun Tong Magistrates Court this morning. The police at the Kwun Tong Magistrate's Court temporarily charged the suspect with two counts of murder last Sunday. The suspect appeared in court this morning at the Kwun Tong Magistrate's Court. Acting Chief Magistrate Zheng Jihang, after listening to the opinions of both the prosecution and defense, decided to postpone the hearing for two weeks until 9:30 am on June 19th, waiting for two psychiatric expert reports to be obtained. The defense did not object. Zheng Jihang approved the application, and the defendant needs to be temporarily detained at Xiaolan Mental Hospital. When the suspect appeared in court, he wore black framed glasses, a light gray shirt, and camouflage green shorts, and was able to answer the judge's questions normally. accordingly

Currently, the highly anticipated summer harvest work in Henan has shifted its focus to the northern region of Henan. According to the Henan Daily client, on June 4th, Lou Yangsheng, Secretary of the Henan Provincial Party Committee, presided over a special video scheduling meeting on the "Three Summers" work in the province, listened to the situation report, analyzed and judged the situation, and arranged and deployed the next steps of work. Governor Wang Kai made specific arrangements. On the evening of May 31, 2023, in Xiafutou Village, Xuliang Town, Boai County, Jiaozuo, Henan Province, villagers braved light rain in the wheat fields to harvest wheat. Visual China Map Lou Yangsheng pointed out that the current summer harvest battle in the province has entered the decisive stage. Doing a good job in summer harvest in northern Henan Province is related to the summer grain yield and seed safety. We should focus on seizing opportunities and make every effort to organize the wheat harvesting work in the northern Henan region, minimize losses, and protect the interests of farmers to the greatest extent possible. Accurate forecasting is essential

On June 4th, the return capsule of the Shenzhou-15 manned spacecraft successfully landed at the Dongfeng landing site. Astronauts Fei Junlong, Deng Qingming, and Zhang Lu all safely and smoothly exited the spacecraft, and the Shenzhou-15 manned flight mission was a complete success. What innovative technologies are there to safeguard the return journey of Shenzhou 15 in this mission? On June 4th, the return capsule of the Shenzhou-15 manned spacecraft successfully landed at the Dongfeng landing site. Xinhua News Agency reporter Lian Zhen photographed that "the sky and the ground" ensure the high-precision return of spacecraft. For the Shenzhou series spacecraft, the return and re-entry GNC technology is directly related to the life safety of astronauts. Taking the success of this return mission as a symbol, China has comprehensively upgraded its GNC system since the Shenzhou-12 manned spacecraft, which features autonomous rapid rendezvous and docking, autonomous adaptive prediction and re-entry return guidance, and has completed a comprehensive update and replacement

At noon today, a Chinese naval fleet consisting of Zhanjiang and Xuchang ships arrived at the assembly area of the "Comodo-2023" multinational maritime joint exercise. It is understood that the assembly anchorage for this exercise is 3 nautical miles long and 1.5 nautical miles wide, capable of anchoring up to 50 ships. Naval vessels from various countries participating in the exercise will also arrive at the anchorage today to complete the assembly of the "Komodo 2023" multinational maritime joint exercise, which is held every two years by the Indonesian Navy. This year is already the fourth edition of the exercise. The exercise will be held from June 5th to 8th in the city of Jakarta, South Sulawesi Province, Indonesia, including the port and sea phases. In the coming days, participating navies from various countries will participate in ship reading style search and rescue exercises, maritime interception and damage management exercises, aerial exercises, and other course objectives exercises

On the evening of June 1st, the US Senate passed a bill on the federal government's debt ceiling and budget, and the flame of the US debt bomb was temporarily extinguished at the last moment. The two parties in the United States have staged an extreme tug of war over the US debt bomb. Some experts believe that the US debt crisis is the result of the reckless politics promoted by the US dollar hegemony, and the underlying cause of this crisis is the highly polarized political system of the US. Since the end of World War II, the US Congress has adjusted the debt ceiling more than a hundred times. The recurring debt crisis will not only have a catastrophic impact on the US economy and people's livelihoods, but also continuously erode the value of US dollar assets such as government credit and US bonds, bringing significant and far-reaching impacts to the global economic landscape. 【
