CCTV Beijing, December 10 (Reporter Huang Yuling) According to the data of the ** Meteorological Observatory, from the 10th to the 11th, the central and eastern regions will usher in a large range of rain and snow weather, and North China and the Huanghuai region will usher in the first large-scale snowfall this winter. This news has attracted widespread attention. In order to provide early warning information to the public in a timely manner, the Meteorological Observatory has issued a Blue Alert for Heavy Snow and a Blue Alert for Cold Wave. **Xu Jun, chief forecaster of the Meteorological Observatory, explained the reasons for the sharp drop and reminded the public to pay attention to relevant matters.
According to Xu Jun's introduction, this cold air will affect almost most of the central and eastern parts of China, and the cooling range will reach 6 8, and some areas will even exceed 12. The reason for this sharp cooling is that before the arrival of cold air, under the action of warm advection of southerly winds and clear sky radiation, there was a significant warming phenomenon in Huanghuai, Jianghan, Jianghuai, central and eastern Jiangnan and parts of South China, with the maximum temperature reaching more than 20. The arrival of stronger cold air this time led to a large increase in the range of cooling.
With the arrival of cold air, significant rain and snow will follow. It is expected that rain and snow will begin to appear in the northern region on the night of the 9th and gradually spread to the east. The time of impact in the Beijing area is expected to end on the morning of the 11th, while the cold air will continue to move southward, affecting the Huanghuai region.
In response to such weather conditions, Xu Jun reminded the public to pay attention to traffic safety and health protection while enjoying the snow scene. Snowfall can cause slippery and icy roads, so you need to be especially cautious when driving. In addition, energy demand is likely to increase due to the larger cooling range, and energy** may be under some pressure.
For areas with heavy snowfall, such as Shaanxi, Shanxi, Hebei, Henan, Shandong and other places, it is necessary to strengthen preventive measures. At the same time, temperatures will drop significantly in most parts of the central and eastern regions, and the public will need to pay close attention to how temperatures change. **The Meteorological Observatory continues to issue a Blue Alert for Heavy Snowfall and a Blue Alert for Cold Wave this morning to remind the public to prepare accordingly.
This large-scale rain and snow is of great significance to the central and eastern regions of China. It not only brings beautiful snow to people, but also increases the moisture of the soil and provides favorable conditions for the overwintering of winter wheat. But at the same time, it is necessary to be careful to deal with the possible adverse effects.
First of all, snowfall can be inconvenient for transportation. Slippery and icy roads on snowy days increase the risk of driving, especially for those who are not familiar with driving in snow. Before traveling, members of the public should check the vehicle's braking system, tire condition, and wipers working properly. At the same time, slow down, keep a safe distance, avoid sudden braking and sharp turns, and ensure driving safety.
Second, a larger cooling may increase energy demand. In cold weather, people often use more heating and gas appliances, which can put some pressure on energy**. In order to cope with possible energy shortages, the public can adjust the indoor temperature appropriately and use heating equipment wisely to save energy and stay comfortable.
In addition, snowfall may also have an impact on agriculture and farmers' livelihoods. Timely snowfall can provide heat preservation and moisture for the overwintering of winter wheat, which is conducive to the growth and development of crops. However, if there is too much snowfall or too cold, it can cause frost damage and disasters to crops. Farmers should pay close attention to the weather forecast and the advice of agricultural experts, and take corresponding protective measures to protect the safety of crops.
Finally, the public should also pay attention to health protection while enjoying the snow scene. Cold weather can increase the risk of colds and respiratory illnesses, especially for older adults and children. When outdoors, keep warm, wear appropriate clothing, wear a mask, and avoid prolonged exposure to the cold.
In general, this large-scale rain and snow weather is of great significance to the central and eastern regions of China, which not only brings beautiful snow scenes, but also provides favorable conditions for agricultural production. However, while enjoying the fun brought by snow, the public should also pay attention to the issues of traffic safety, energy use and health protection, and prepare accordingly to ensure their own safety and normal life.
