The first cold wave this winter is coming. What is the weather condition like everywhere?

The first cold wave warning this winter is coming, which will have a great impact on various places.

According to the Central Meteorological Observatory, starting from December 13, relevant departments will continue to issue cold wave blue warnings: Affected by strong cold air, the eastern part of Northeastern China, the southeastern part of Northwest China, most of North China, and Most of the Huanghuai, most of the Jianghuai, Jianghan, Jiangnan, the eastern part of Southwest China, and most of South China will successively cool down by 6 to 8°C. Among them, some areas in southwestern Hunan, southeastern Guizhou, and central and northern Guangxi will cool down. up to 10℃. After the cooling, the minimum temperature line of 0℃ will press southward to the line from southern Guizhou to northwest Zhejiang. There are northerly winds of magnitude 4 to 6 and gusts of magnitude 7 to 8 in the northern region, northerly winds of magnitude 4 to 5 in the south, gusts of magnitude 6 to 7 on rivers and lakes, and gusts of magnitude 6 to 8 and gusts of magnitude 9 in offshore areas. northerly wind.

So, how should we prevent the cold wave?

For individuals, we must do the following:

1. Close doors and windows and secure outdoor structures.

2. Residents should pay attention to adding clothes to keep warm, especially to protect the elderly and weak patients from cold.

3． Take measures to keep warm and prevent slipping when going out, and be careful of slippery roads and falls.

4. Drivers should take anti-skid measures, pay attention to road conditions, obey instructions, and drive slowly.

5. Herdsmen should drive wild livestock into sheds for feeding.

6. Ships should seek shelter from the wind, and outdoor workers at heights, on water, etc. should stop working.

7. People in dangerous buildings should evacuate quickly, especially during a snowstorm.

8. Beware of gas poisoning, especially for residents who use coal stoves for heating.

9． If you are trapped by a snowstorm, call for help as soon as possible.

For agriculture, relevant practitioners should do the following:

First, since the wind is strong when the cold air comes, scaffolding facilities should be reinforced to prevent them from falling. If the frame collapses or strong wind lifts the shed film, freezing damage will be aggravated, and temperature and humidity control must be done.

Second point, rapeseed, green manure and citrus orchards in low-lying areas should pay attention to clearing trenches and draining water to prevent accumulation of water from freezing and aggravating freezing damage; leafy vegetables can be covered with straw to reduce freezing damage.

The third point is to cover the vegetable or flower greenhouse with insulation materials such as straw mats and double-layer films to increase the temperature inside the greenhouse.

The fourth point is that poultry and livestock farmers should do a good job of cold-proofing and insulating the poultry and livestock sheds. The lighting time should also be increased in the poultry breeding sheds to increase the egg production rate; aquaculture ponds should be filled with water to adjust the temperature. And appropriately reduce the amount of feeding.

As for transportation, the following points must be achieved:

First, supervision and early warning must be strengthened. All units must strengthen emergency duty, strengthen supervision and early warning, make full use of existing monitoring methods, strengthen monitoring of ships in waters affected by cold wave strong winds, and promptly remind relevant water-related units and construction companies to prepare for prevention.

Second point, maritime departments at all levels must conduct key inspections on "four passengers and one danger" ships, sand transport ships, unpowered ships, construction ships and anchoring ships, and strictly control seaworthiness. At sea, fishing boats and farmed fish rafts should be reminded to take shelter from the wind.

In short, the first cold wave warning this winter is coming, which will have a certain impact on people across the country. People must pay attention to keeping warm and cold.
