Recently, the temperature in the northern part of China has risen significantly, and the south will also be close to the same period of the year or high. This is a significant change since mid-December, after China has encountered a variety of winter disastrous weather such as cold waves, rain and snow, low temperatures, and freezing. However, although the temperature will rise and the south will be close to the same period of the year or high, we still need to pay close attention to future weather changes and do a good job in disaster prevention and mitigation.
According to the data of the meteorological department, since mid-December, the temperature in the central and eastern parts of China has been significantly low, and the precipitation process is frequent and extreme. Widespread heavy snowfall and obvious snow cover occurred in North China, Huanghuai and other places. From the 10th to the 11th, moderate to heavy snowfall and local blizzard occurred in North China, Huanghuai, south-central Inner Mongolia, central and northern Shaanxi, eastern Liaoning, and southeastern JilinFrom the 13th to the 16th, there was widespread snowfall, sleet or rain turning to snow in the north of the middle and lower reaches of the Yangtze River, and heavy snowfall or heavy snowfall occurred in the southeast of Shanxi, the central and southern parts of Hebei, the central and northern parts of Henan, the northwestern part of Shanxi and the peninsula.
A cold wave is a natural weather phenomenon in which cold air from high latitudes rapidly strengthens and invades into middle and low latitudes under specific weather conditions, causing widespread severe cooling, strong winds, rain and snow in areas along the way. When this kind of cold air invades southward and reaches a certain standard, it is called a cold wave. The cold wave that invaded our country was mainly in the Arctic zone, Siberia in Russia, and Mongolia in other places. These areas are covered with snow and ice for long periods of time in winter, and the air masses that stay in those areas are getting colder and drier. When this cold air mass accumulates to a certain extent, and the air pressure increases to a much higher level than that in the south, it is like a flood stored in a high mountain, and at the first opportunity, it floods and pours down to the south with lower air pressure, which forms a cold wave.
The disastrous weather brought by the cold wave has brought great inconvenience to people's travel, production and life. Widespread snowfall and low temperatures have caused icy roads and blocked traffic, posing a serious threat to people's travel safety. In addition, the cold spell has had a significant impact on agricultural production and electricity**. Persistent low temperatures have inhibited crop growth, and increased demand for electricity has put a lot of pressure on power supplies.
Although the temperature in the north will rise significantly, and the south will also be close to the same period of the year or high, it is still necessary to pay attention to weather changes and do a good job in disaster prevention and mitigation in the future. The meteorological department will continue to closely monitor weather changes and issue early warnings in a timely manner to remind the public to pay attention to safety. At the same time, all regions also need to take effective measures according to the actual situation to strengthen traffic safety management, agricultural production and power security.
In short, although the temperature will rise and the south will be close to the same period of the year or high, disaster prevention and mitigation still need attention. We must always be vigilant, pay attention to weather changes, and take preventive measures to ensure the safety of people's lives and property. At the same time, it is also hoped that relevant departments can strengthen cooperation to jointly respond to the challenges brought about by disastrous weather and create a safer and more stable living environment for the people.
