In what season does cold wave weather often appear? When did the cold wave occur?

Lead: When traveling in cold weather, drivers and friends should pay attention to anti-skid, slow down when driving, be careful and don't be impatient. So, when did the cold wave happen? In what season does cold wave weather often appear?

Time period of cold wave occurrence

Cold waves occur in late autumn, winter and early spring. Cold wave is cold air from polar regions or cold zones in winter, which invades the middle and low latitudes on a large scale like tides. When a cold wave strikes, the temperature will drop sharply, accompanied by strong winds, rain and snow. It has a serious impact on industrial and agricultural production, people's lives and human health.

Cold wave is a natural weather phenomenon. Refers to the cold air from high latitudes, which is rapidly strengthened in a specific weather situation and invades the middle and low latitudes, causing a wide range of severe cooling, strong winds and rain and snow weather along the way. When this cold air reaches a certain standard, it is called a cold wave. Cold wave is a kind of cold air, not all cold air is cold wave, it is the "king" of cold air.

What are the hazards caused by the cold wave?

1, the severe cooling caused by the cold wave will cause freezing damage to crops, thus affecting the grain output in the coming year.

2. The heavy snow and freezing rain brought by the cold wave will damage wires and telephone poles, causing traffic danger.

3. The strong wind accompanying the cold wave may destroy buildings and farms, causing casualties.

How to deal with cold weather?

1, be sure to keep warm, wear thick clothes, and try to ensure that the body heat is not easily lost.

2, doors and windows should be closed, pay attention to ensure smooth outdoor fresh air circulation.

3. In rainy and snowy weather, pay attention to the adverse effects of slippery roads and snow and ice on traffic. Keep a safe distance between motor vehicles to avoid unnecessary losses.

Cold wave main influence area

After entering China from central Siberia and Mongolia, it passes through Hetao area and south-central China. From eastern Siberia or eastern Mongolia, it enters the northeast of China and goes south through North China. When the cold wave comes, you must keep warm and wear thick clothes to ensure that the body heat will not be easily lost, so that it is not easy to get frostbite and get sick. When going out, you'd better put on a hat, scarf and gloves for yourself. Hands, neck and head are also the main parts of human heat loss, so when the cold wave strikes, we should pay attention to keeping these parts warm to avoid frostbite.

Now some areas are about to usher in a cold wave, and which areas in China will be affected by this cold wave. Are there any preventive measures for the cold wave? Many friends want to know the answer to this question. Let's have a quick look. Where does the cold wave affect China? 1, west road, entering Xinjiang, China from West Siberia, and advancing southeast via Hexi Corridor. After entering China from central Siberia and Mongolia, it passes through Hetao area and south-central China.

Main distribution areas of cold wave in China

After entering 10, the cold air in China is becoming more and more active, and with the arrival of winter, the intensity of cold air will become stronger and stronger. When the cold air reaches a certain intensity standard, it is a cold wave. Many people are curious: Where do the annual rounds of cold air and cold waves come from? Do you know where the cold wave mainly occurs in China? Where does the cold wave mainly occur in China? There are three main paths for the cold wave to invade China. West Road: Entering Xinjiang, China from West Siberia, and advancing to the southeast via Hexi Corridor.

Middle Road: After entering China from central Siberia and Mongolia, it passes through Hetao area and south-central China. East Road: Enter the northeast of China from eastern Siberia or eastern Mongolia, and go south via North China. East Road and West Road: The cold air in East Road goes south from the lower reaches of Hetao, and the cold air in West Road goes south from the southeast of Qinghai. Two cold air often meet on the east side of the Loess Plateau, between the Yellow River and the Yangtze River, causing a wide range of rain and snow, and then the two cold air meet south, causing strong winds and obvious cooling.
