As the New Year approaches, with the arrival of a strong cold air in the north, it has already affected the Zhejiang region. Most areas of Zhejiang have experienced severe cooling, strong winds, rain, snow, and freezing weather. It is expected that the cold air will reach the "cold wave" level in the next few days, with an average cooling range of 12 ℃ to 14 ℃, with a minimum of -11 ℃ and moderate to heavy snow.
The Zhejiang Meteorological Observatory has initiated a Level IV emergency response to the low-temperature rain, snow, and freezing disaster.
The Central Meteorological Observatory has issued an emergency notice that a cold wave is approaching at the end of the year, and the coldest weather in Zhejiang Province has entered winter. The temperature is also decreasing faster and faster. Let's take a look at the weather forecast for the next few days.
The intensity of this cold wave process is strong, with a fast southward movement speed. The warm and humid air flow is quickly compressed into the South China Sea area, and China's land is basically controlled by cold air. Therefore, from the 28th to the 29th, there will be brief rainy and snowy weather in the eastern part of Northwest China, southern part of North China, Huanghuai, Jianghuai, Jianghan, and other areas. As the cold air descends southward, the precipitation will soon end.
The condition for the formation of freezing rain is that the temperature near the ground is low, and the temperature in the middle and upper layers is relatively high due to the control of warm and humid air flow. During this weather process, cold air controlled everything from lower to middle to upper levels, making it less likely to form freezing rain.
According to the degree of strength, China divides cold air into four levels: weak cold air, strong cold air, strong cold air, and cold waves.
Only when cold air passes through the area and the temperature drops by more than 8 ℃ within 24 hours, and the minimum temperature drops below 4 ℃, or when the temperature drops by more than 10 ℃ within 48 hours and the minimum temperature drops below 4 ℃, such cold air is eligible to be called a "cold wave".
How to prevent coldness among citizens during the cold wave period
1： Close the window to prevent cold
When the weather is cold, especially at night, all windows facing north, such as balconies, kitchens, bathrooms, and corridors, should be tightly closed to ensure that the temperature inside and in the corridors is above zero degrees Celsius.
2： Dripping into a line
In severe cold weather, if the temperature is below -3 ° C, the tap can be slightly turned on at night to make the water drip into a line, ensuring that the tap water inside the pipe flows to prevent freezing at night.
3、 Evacuation facilities
Long term uninhabited: Close doors and windows, close water meter valves, turn on household faucets, and vent water pipes.
Solar water heater: If the solar water heater is installed outdoors, the water pipe should be equipped with an anti freezing drainage device. When the temperature is continuously below -3 ° C, it should be drained to prevent freezing.
4： Pay attention to preventing cold and keeping warm
When going out, wear more clothes, hats and scarves, and add more warm clothes to prevent colds and fever, ensuring one's physical health.
5： Slow travel
It is necessary not to go out in adverse weather such as rain, snow, and low temperatures, and plan your time reasonably before traveling. Whether driving or walking, pay attention to walking slowly to prevent slipping.
