Why have abnormal weather increased in recent years?

According to the notification from the National Defense General Administration and the Ministry of Water Resources, the Yellow River Defense General Administration organized the 20 17 ~ 20 18 yellow river ice Chamber of Commerce in Zhengzhou, Henan Province, to review and summarize the ice prevention work in the previous year, analyze and judge the ice prevention situation, and arrange and deploy the ice prevention work this year. The National Defense General sent personnel to attend the meeting and put forward clear requirements for anti-icing work.

The meeting held that in recent years, abnormal weather in China has increased significantly, meteorological instability factors and disaster risks have increased, and there are still weak links in engineering and non-engineering measures to prevent ice flood. The basic characteristics of the Yellow River ice flood, such as sudden, unpredictable, difficult to defend and difficult to rescue, have not changed, and more and more bridges across the river still exist. The ice situation of the Yellow River is grim.

The meeting emphasized that in 20 17 ~ 20 18, yellow river ice should take the prevention of the worst ice flood in the history of the Yellow River as the main line, ensure the safety of people's lives, ensure that important dikes are not breached, and minimize the loss of ice flood disasters.

The meeting pointed out that, first, we should strengthen leadership and compact the responsibilities of preventing ice. It is necessary to improve and perfect various responsibility systems, further strengthen the responsibility for preventing ice-breaking, take the chief executive responsibility system as the core, refine and implement the responsibilities step by step, and conduct pressure at different levels to ensure that people are caught in ice-breaking, problems are managed and responsibilities are borne.

Second, we must improve the plan and implement various flood control measures. It is necessary to revise and improve the pre-plan system for ice prevention and rescue, emergency flood diversion, relocation and rescue, material support and emergency response to sudden ice conditions, carry out targeted anti-ice rescue drills, and further test the pertinence and operability of the pre-plan.

Third, we should strengthen monitoring and scientifically dispatch water conservancy projects. It is necessary to closely monitor major weather processes and changes in ice conditions and make timely forecasts and early warnings. It is necessary to scientifically dispatch key reservoirs such as Longyangxia, Liujiaxia, Haibowan, Wanjiazhai and Xiaolangdi to accurately control the flow.

Fourth, we should strengthen supervision and eliminate hidden dangers of flood control. It is necessary to do a good job in river clearing, list the responsibilities and tasks of clearing obstacles in the jurisdiction, actively carry out supervision and inspection, and thoroughly remove traffic obstacles. It is necessary to urge the construction unit of the river-crossing bridge under construction to complete the flood control construction plan during the flood season and implement various flood control measures.

Fifth, we must strengthen defense and eliminate all kinds of dangers in time. During the flood season, we should adhere to the 24-hour emergency duty and strengthen the inspection and defense of dikes, sluice stations and other projects. For major dangers such as ice jam and ice dam, comprehensive measures such as bombing, grabbing and sorting should be taken to timely and effectively grab and protect them to ensure the safety of ice prevention.

Sixth, we must coordinate and form a strong anti-icing force. All levels of defense should give full play to the functions of unified command, organization and coordination. All relevant departments shall, in accordance with the division of responsibilities, do a good job in anti-icing and disaster relief. It is necessary to strengthen ties with the People's Liberation Army and the Armed Police Force, and strengthen coordination and linkage between the military and the land.
