On the first day of construction, the cold wave "tailged" the Spring Festival holiday. On the morning of February 18, the ** Meteorological Observatory raised the cold wave warning to orange, which is also the highest level of cold wave warning.
It is expected that from February 18 to 22, most parts of China will have a sharp cooling from west to east and from north to south. In some areas of Inner Mongolia, Northeast China, Hubei, Hunan and other places, the cumulative cooling range can reach more than 20. The cold wave will also be accompanied by high winds and dust, and the Meteorological Observatory has issued a blue warning for high winds and a blue warning for sandstorms at the same time.
On the 18th, three warnings of cold wave, strong wind, and sandstorm were issued at the same time!
According to the ** Meteorological Observatory, affected by the cold wave, it is expected that from February 18 to 22, most of our country will be drastically cooled from west to east and from north to south, and the average temperature will generally drop by 8 to 12, and the temperature in the southern Xinjiang Basin, most of Inner Mongolia, the eastern part of Northwest China, most of North China, Northeast China, Huanghuai, Jianghuai, Jianghan, Jiangnan, central and northern South China and Guizhou will drop by 12 to 18, of which, the cumulative cooling range in some areas of central and eastern Inner Mongolia, Northeast China and Hubei, Hunan and other places can reach 20 Above.
Around February 23, the minimum temperature 0 line will be pressed south to Jiangsu, central and southern Anhui to southern Hunan and southern Guizhou.
From 8 o'clock on February 18 to 8 o'clock on the 20th, the southern Xinjiang Basin, most of Inner Mongolia, the eastern part of Northwest China, the northern part of North China, the northeast region, Huanghuai, Jianghuai, Jianghan, northern Jiangnan and other places will be cooled by 6 to 10, of which, the western part of the Southern Xinjiang Basin, most of Inner Mongolia, most of the Northeast and other places will be cooled by 12 to 16, and the local temperature can reach more than 18.

At the same time, the cold wave weather will also be accompanied by strong winds and dust, ** The Meteorological Observatory issued a blue warning for high winds and a blue warning for sandstorms at the same time.
It is expected that from 8 o'clock on February 18 to 8 o'clock on the 19th, there will be strong winds of 5 to 6 and gusts of 7 to 8 in the eastern part of the southern Xinjiang Basin, the central and western parts of Xinjiang, the southern part of Qinghai, the western part of Gansu, the central and western parts of Inner Mongolia, and the central and western parts of Liaoning; The Bohai Sea, the Bohai Strait, the northern Yellow Sea, and the northern East China Sea will have strong winds of 7 to 8 with gusts of 9 to 10.
From 8 a.m. on February 19 to 8 a.m. on the 20th, there will be strong winds of magnitude 5 to 6 and gusts of 7 to 8 in the central and western regions, southern Qinghai, Hexi in Gansu, central and eastern Inner Mongolia, western and southern Liaoning; The Bohai Sea, the Bohai Strait, and most of the Yellow Sea will have strong winds of 7 to 8 and gusts of 9 to 10.
In addition, due to the influence of cold air and strong winds, it is expected that from 8 o'clock on February 18 to 8 o'clock on the 19th, there will be sand or floating dust weather in parts of eastern Xinjiang and southern Xinjiang Basin, western Inner Mongolia, southern Gansu, Ningxia, most of Shaanxi, western Shanxi and other places, and there will be sandstorms in the western and southern parts of Xinjiang Southern Xinjiang Basin, northern Ningxia and northern Shaanxi.
Meteorological experts reminded that the weather situation in this round of cold wave weather process is complex, the temperature rises first and then falls, the fluctuations are drastic, the influence range of wind, sand, dust and snow is very wide, and the intensity of rain and snow in the later period is not weak. At present, it is the return period of the Spring Festival, so it is necessary to pay attention to the weather changes in time and arrange the itinerary reasonably.
When a snowstorm hits, try to stay indoors and don't go out; When the temperature drops suddenly, add clothes in time to prevent frostbite; Stay away from billboards, temporary structures and old trees outdoors to avoid smashing injuries; Pedestrians should avoid walking on ice-covered roads and beware of slippery and falling; When driving, take anti-skid measures, reduce your speed, and avoid sharp turns and braking.
At the same time, it is necessary to pay attention to outdoor cold and warmth. Increase clothing according to the temperature and your own situation, and pay attention to the warmth of your head, neck and joints, such as wearing hats, scarves, gloves, etc.
Keep the room warm and ventilated. Electric heaters and other equipment can be used for heating to maintain a suitable indoor temperature, and at the same time, windows should be opened frequently for ventilation to maintain air circulation; Avoid using coal stoves, charcoal fires, etc. in closed places to prevent carbon monoxide poisoning.
In addition, according to the "Guidelines for Public Health Protection during Cold Waves" issued by the National Bureau of Disease Control and Prevention, a drop in temperature can cause the body's blood vessels to constrict and increase the respiratory rate. During the cold wave, cold weather is easy to cause superficial damage and form chilblains, aggravating the pain of patients with arthritis and rheumatoid arthritis. It is easy to induce airway spasm and abnormal immune function of the respiratory system, causing acute exacerbation of chronic obstructive pulmonary disease, acute attack of bronchial asthma, acute respiratory infection and other respiratory diseases. Sensitive groups such as infants, children, pregnant women, and the elderly, people with chronic underlying diseases, and outdoor workers should focus on protection.
