Good morning, dear friends, today is December 21st, eight o'clock in the morning. I have a big doubt, didn't the experts say that this year is a warm winter? Why look at the latest weather forecast, tomorrow we will usher in a new round of cold wave and cold air, which is expected to bring rain and snow on December 22 and 23. Will this be a warm or cold winter?
A cold wave refers to the strong cold air transported to the middle and high latitudes during the activity of polar or cold cyclones. The formation of cold waves is often associated with atmospheric circulation patterns such as the Arctic Oscillation (AO) and the North Atlantic Oscillation (NAO). When these oscillations are in negative phase, the cold air from the polar regions tends to spread southward, affecting the middle and high latitudes.
The characteristics of the cold air during this cold wave are as follows. Intensity: According to the forecast of the meteorological department, the intensity of the cold air in this cold wave is relatively large, which will bring significant cooling, strong winds, rain and snow to many places in China. Wide range of impact: The cold air will affect most of northern China, as well as parts of the south. The affected areas include Inner Mongolia, Heilongjiang, Qinghai, Gansu, Ningxia, Shaanxi, Shanxi, Hubei and Sichuan. Longer duration: The impact of this cold wave is expected to last for many days, which will have a great impact on agricultural production, transportation and people's lives across China.
According to the forecast of the meteorological department, light snow or sleet will occur in the following areas of China on December 22 and 23:
Western Inner Mongolia: This region is located in northern China, and the cold air will have a certain impact on its agricultural production and transportation.
Central Heilongjiang: As an important agricultural production base in Northeast China, this rain and snow will adversely affect local agricultural production.
Northern and eastern Qinghai: Located in the plateau area, this cold wave and cold air may cause icy roads and transportation disruptions.
Hexi, Gansu: The region is located in northwest China, and the cold air will have a great impact on local agricultural production and residents' lives.
Ningxia Central and North: Located in northwest China, this cold wave will have a certain impact on its agricultural production and transportation.
Northern Shaanxi: As an important agricultural production base in northern China, the rain and snow will adversely affect local agricultural production.
Northern Shanxi: This region is located in northern China, and the cold air will have a great impact on local agricultural production and residents' lives.
Southwest Hubei: Located in southern China, the cold air will have a certain impact on agricultural production and transportation.
Western Sichuan Plateau: As an important agricultural production base in southwest China, this rain and snow will adversely affect local agricultural production.
In the face of rain and snow brought by a new round of cold wave and cold air, local governments and relevant departments should take the following measures:
Strengthen monitoring and early warning: Meteorological departments should strengthen the monitoring and early warning of cold waves and cold air, issue weather forecasts in a timely manner, and remind residents and relevant departments to take precautions.
Safeguard agricultural production: Local governments should take measures to strengthen guidance and support for agricultural production and reduce the impact of cold waves and cold air on agricultural production.
Ensure traffic safety: The transportation department should strengthen road inspection and maintenance to ensure that roads are smooth and prevent traffic accidents.
Raise residents' awareness of cold protection: Local governments should strengthen publicity and education for residents, and remind residents to do a good job of cold protection and warmth, especially the elderly and children.
Strengthen energy supply security: Local governments should ensure a stable energy supply to meet the needs of residents and industrial production.
A new round of cold wave and cold air is coming, and many places in China are ushering in rain and snow. In the face of this cold wave, local governments and relevant departments should take effective measures to ensure the safety and stability of agricultural production, transportation and residents' lives. At the same time, residents should also pay attention to the weather forecast, do a good job of cold protection and warmth, and ensure their own safety.
