The Meteorological Bureau issued a blue warning signal for cold wave. Which urban areas have obvious cooling conditions?

The first cold wave warning will strike this winter, which will have a great impact on all localities.

According to the Central Meteorological Observatory, from1February 13, the relevant departments continued to issue a blue warning of cold wave: affected by strong cold air, most of the northeast, southeastern northwest, most of North China, most of Huanghuai, most of Jianghuai, Jianghan, Jiangnan, eastern southwest, and most of South China will be cooled by 6 ~ 8 C successively, among which, southwestern Hunan, southeastern Guizhou, and southern China will be affected by strong cold air. After cooling, the minimum temperature line of 0℃ will be pressed south to the line from southern Guizhou to northwestern Zhejiang. There are 4 ~ 6 northerly winds with gusts of 7 ~ 8 in the north, 4 ~ 5 northerly winds in the south, 6 ~ 7 gusts in rivers and lakes, and 6 ~ 8 northerly winds with gusts of 9 in the offshore.

So, how should we guard against the cold wave?

For individuals, we must do the following:

1. Close the doors and windows and fix the outdoor structure.

2. Residents should pay attention to adding clothes to keep warm, especially for the elderly and infirm patients.

3. Take measures to keep warm and prevent slipping when going out.

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

Herdsmen should drive wild animals into sheds to feed them.

6. Ships should be sheltered from the wind, and outdoor workers such as high altitude and water should stop working.

People in dangerous houses should be evacuated quickly, especially in the case of 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 employees should do the following:

First, due to the strong wind when cold air comes, scaffolding facilities should be strengthened to prevent scaffolding from collapsing or shed film from being lifted by strong wind to aggravate the freezing injury, and the temperature and humidity should be controlled well.

Secondly, rape, green manure and citrus orchards in low-lying areas should pay attention to ditch cleaning and drainage to prevent stagnant water from freezing and aggravate freezing damage; Leaf vegetables can be covered with straw to reduce freezing injury.

Third, the vegetable or flower greenhouse is covered with straw mats, double-layer films and other thermal insulation materials to increase the temperature in the greenhouse.

Fourthly, poultry and livestock farmers should do a good job of cold protection and heat preservation in poultry sheds, and increase the light time in poultry sheds to improve the egg production rate; Water is injected into the culture pond to adjust the temperature and reduce the dosage of bait appropriately.

For transportation, we must do the following:

First, we must strengthen supervision and early warning. All units should strengthen emergency duty, strengthen supervision and early warning, make full use of existing monitoring methods, strengthen the monitoring of ships in waters affected by cold waves and strong winds, and promptly remind relevant wading units and construction enterprises to make preparations for resisting Taiwan.

Secondly, maritime departments at all levels should pay special attention to "four passengers and one danger" ships, sand carriers, unpowered ships, construction ships and anchor ships, strictly control the seaworthiness, and remind fishing boats and breeding rafts at sea to enter the harbor to avoid the wind.

In short, the first cold wave warning this winter will have a certain impact on the people of the whole country, so we must pay attention to cold and warmth.
