This article describes the impact of the Siberian cold wave that began on December 9 on China. The cold wave entered the Heilongjiang River basin through the East Siberian cold vortex, and the cold air penetrated into Northeast China, causing extremely cold weather in Northeast China. In addition, two cold air teams moved separately, one into the North China Plain and the other into the North China Plain from the ocean, causing widespread cooling in southern Hebei, northern Henan and northern Shandong. With the arrival of warm and humid airflow from the south, it is expected that the north will usher in widespread rain and snow from the evening of December 9.
The incident has attracted widespread attention and discussion on the Internet. Many people have ** information about the incident, expressing concern and concern for this cold wave. Some netizens questioned the effectiveness of the meteorological observatory's early warning of the cold wave and were worried about the impact on social life. In addition, some netizens shared the temperature and weather conditions in their places of residence, so that more people can understand the severity of cold weather.
The southward movement of cold air from the Siberian cold wave is not new. Similar cold spell events have occurred several times in China over the past few years, each time bringing severe cold and snowfall to the northern regions. For example, the "sandstorm before the rainy season" in 2018 and the "extremely cold weather in the north" in 2019 have both aroused widespread attention and discussion.
The cold wave has had a great impact on traffic, roofs, vegetation and human health in the northern region. Due to the heavy snowfall and the complex and rapidly changing precipitation patterns, the risk of road icing and traffic accidents increases. Snow on roofs can cause damage to homes, and freezing vegetation can reduce crop yields. In addition, low temperatures and cold weather pose a certain threat to human health, so people should pay attention to keeping warm and cold.
According to the latest**, the center of the blizzard will be moved to Liaodong and Changbai Mountains on December 11, and the Dalian area may also be affected by the blizzard, but then the blizzard will end quickly. However, this cold wave is only the beginning, and the cold wave on the west road will move southward from December 15, and the country will usher in a more drastic cooling.
The cold spell caused a sharp drop in temperatures and heavy snowfall in northern China, adversely affecting transportation, crop yields and human health. Although the cold wave comes and goes quickly, with the successive cold air, the cold weather will tend to be severe across the country. People need to strengthen cold protection measures and prepare in advance to cope with the challenges brought by cold weather.
