　　　　In addition, six ships in Yantai sea area were in danger, and all 68 people in distress escaped from danger, including 20 crew members from Pakistan, Malaysia and other countries.

　　　　■ Interpretation of causes

　　　　Frequent extreme weather and global warming are the main reasons.

　　　　Experts from the Central Meteorological Observatory said that the strong warm and humid airflow encountered active cold air and extreme weather occurred; Some experts also said that it has nothing to do with warm winter.

　　　　After the second warmest winter in more than 50 years, most parts of northern China have experienced a large-scale snowfall that is rare all the year round, and the coastal waters have also encountered a storm surge that comes once in decades.

　　　　Meteorologists said that in recent years, affected by global warming, some extreme weather and climate events are appearing frequently.

　　　　Xu Liangyan, a senior engineer at the National Climate Center of China Meteorological Bureau, said that warm winters mainly appeared in the context of global warming. In this case, some extreme weather and climate events are prone to occur. According to meteorologists, the intensity of this snowfall is rare in the same period of several decades. This is mainly because the warm and humid airflow is relatively strong after the warm winter, and the cold air is relatively active recently. The combined effect of cold and warm airflow has led to a large-scale snowfall in the northern region.

　　　　In addition, the biggest storm surge since 1969 began in the coastal waters of China on the 3rd night. Huang Bin, a marine forecaster of China Meteorological Bureau, said that such a large-scale storm surge rarely appeared in the spring. The storm surge was caused by the temperate cyclone, that is, the cold current, and it coincided with the astronomical tide, so the sea level rose abnormally.

　　　　However, some meteorologists said that the frequent foggy weather in February and the drought in some areas could not be regarded as extreme weather and climate events. Han Jiangwen, chief forecaster of Shenyang Central Meteorological Observatory, said that the snowstorm in Liaoning is an extreme weather, which is not directly related to the warm winter weather, but is formed by the superposition of various meteorological factors.

　　　　■ countermeasures

　　　　Some primary and secondary schools in the three northeastern provinces are closed, and social vehicles in Shenyang are restricted to single and even numbers.

　　　　Large-scale snowfall since March 4 has affected the normal teaching of some primary and secondary schools in Jilin Province. At present, the school buildings in some areas have been damaged in the snowstorm, and the education departments in some cities have issued urgent notices to suspend classes in primary and secondary schools to prevent students from accidents.

　　　　The reporter learned from the Education Bureau of Mudanjiang City, Heilongjiang Province that since the snowstorm, the Meteorological Observatory of Heilongjiang Province and the Meteorological Department of Mudanjiang City have successively issued the red warning signal of snowstorm in Mudanjiang area, in order to avoid the impact of snowstorm on school teaching and student safety, all primary and secondary schools in this city will have a holiday from the afternoon of the 5th.

　　　　Primary and secondary school students in Shenyang and Dalian, Liaoning Province continued to suspend classes. With the consent of the Shenyang Municipal People’s Government, all primary and secondary school students in Shenyang continued to suspend classes due to the snowstorm on the 6th. Due to the strong wind in Dalian, 550,000 junior high school and primary school students in Dalian continued to suspend classes on the 6th, and 230,000 senior high school and vocational school students resumed classes.
