First of all, the most direct impact of cooling is that people's lifestyles have changed significantly. Low temperature weather causes residents to strengthen warm-keeping measures, put on heavy clothes and use heating equipment to cope with cold weather. At the same time, the phenomenon of road icing has increased, which has brought some troubles to driving. Remind drivers and friends to be vigilant during driving, pay attention to slow down and ensure travel safety.
Secondly, the cold weather has also brought certain challenges to agricultural production. Cold weather hinders the growth of crops, and some vegetables in early spring may be frozen, which requires farmers to strengthen management and protection. At the same time, for aquaculture, it is very important to strengthen animal warm-keeping measures reasonably to ensure the health and production of livestock.
In addition, the cold weather has brought some pressure on energy consumption and supply. As the temperature drops, people's demand for home heating increases greatly, and the consumption of energy such as electricity and gas also increases accordingly. The operation stability of heating system is facing a test, and relevant departments need to strengthen monitoring and maintenance to ensure the normal heating of residents.
However, the cold weather has also brought business opportunities to some industries. The market of clothing, baby warmers and heating equipment is active, which intensifies the competition in related industries. At the same time, ice and snow tourism has also been promoted, and the ice and snow carnival held in various places has attracted a large number of tourists to Shandong to feel the charm of winter.
Cold air intensity
According to the intensity, cold air in China is divided into five grades: weak cold air, moderate cold air, strong cold air, strong cold air and cold wave.
1, weak: cold air that makes the daily minimum temperature in a place lower than 6℃ within 48 hours.
2. Medium: cold air that reduces the daily minimum temperature in a certain place by more than or equal to 6℃ but less than 8℃ within 48 hours.
3. Strong: cold air that makes the daily minimum temperature in a certain place drop more than or equal to 8℃ within 48 hours, but fails to make the daily minimum temperature in that place drop below 8℃.
4. Strong: cold air that makes the daily minimum temperature in a place drop more than or equal to 8℃ within 48 hours, and makes the daily minimum temperature in this place drop below 8℃.
5. Cold wave: cold air that reduces the daily minimum temperature in a place by ≥8℃ within 24 hours, or ≥ 10℃ within 48 hours, or ≥ 12℃ within 72 hours, and reduces the daily minimum temperature in the place to below 4℃.
