Original title: Perfect connection! A new round of more extensive rain and snow will cover 60% of the land of my country this weekend
China Weather News reported frequent cold air activities this week, with the largest variety of rain and snow since the Year of the Ox since the 24th. Starting tomorrow (February 27), a new round of rain and snow will be released. , with a greater range than the previous round. The weekend will cover about 60% of our country. The northern part of the blizzard will refresh the greatest variety of rain and snow since the Year of the Ox. At the same time, the temperature fluctuates frequently in various places, the pace of the transition between cold and warm is rapid, and some areas will have a windy and sandy climate.
Currently there are two cold winds that affect my country. The cold air above began to bring the most rain and snow since the Year of the Ox on the 24th. Precipitation at more than 100 weather stations in Shanxi, Henan, Shaanxi, Shandong and elsewhere exceeded the February historical period. value.

A new wave of cold air began to affect Xinjiang yesterday. There were heavy snowfalls along the Tianshan Mountains and northwest, local blizzards in Changji and Urumqi, and most of northern Xinjiang decreased from 6 to 12 ° C. Gusts from Alashankou 11, the strongest wind A 32 At 3 meters per second, the force of cold air is evident.
A new round of large-scale rain and snow covers about 60% of my country’s land with blizzards in the north
As a new wave of cold air moves east, starting tomorrow, a new round of large-scale rain and snow “smoothly” will cover about 60% of my country’s land on weekends, which is larger than the previous round of rain and snow. The greatest variety of rain and snow since the beginning of the year.
According to Zhang Juan, meteorological analyst at China Weather Network, due to the replenishment of water vapor in the east, the range of rain and snow in the north will be wider this time, but the intensity of rain and snow is generally more weak than the above.
There will be snow or sleet in the eastern part of northwest China, the western and northern parts of northern China, and the northeast. Among them, some areas in eastern Gansu, northern Shaanxi, eastern-central Inner Mongolia, western and northern northern China and the northeastern regions will have moderate to heavy snowfall. There is a blizzard. The main period of snowfall is 27-28, the accumulated precipitation is 3-8mm, the local area can reach 10-15mm, the new snow depth is 2-6cm, and the mountainous area can exceed the 10 cm.
There were light to moderate rains in the southern part of northern China to Guanzhong in Shaanxi and most areas to the south, and heavy rains in the northern part of southern China. The main rainy period was from February 28 to March 1.
Zhang Juan recalled that for Shaanxi, Shanxi, Henan, Shandong and other places, the interval between two rounds of rain and snow is not long, and it is necessary to prevent the adverse effects of snowfall, snow, ice, etc. in transit. . This precipitation process in the central and eastern regions is beneficial in alleviating meteorological drought, improving soil moisture in the winter wheat zone, and reducing the level of risk of meteorological fires in forests and grasslands. However, winter wheat in parts of Henan and Shandong may enter the bonding period one after another, and the ability to resist freezing will rapidly decline The adverse effects of low-temperature rain and snow on wheat.
Cold and heat change rapidly, the local temperature drops more than 14 ℃, the wind and dust come
In terms of temperature, the period of time affected by cold air is different, the temperature in various places fluctuates frequently, and the pace of the transition between cold and warm is relatively fast. From February 26 to March 1, the temperature in most areas north of the middle and lower reaches of the Yangtze River dropped by 6 to 10 ° C. Among them, the temperature in the central and eastern parts of Inner Mongolia and the central and northern parts of northeast China could fall more than 14 ° C.
In the next three areas, temperatures in Northwest, North China, and Northeast China will first rise and then fall. Among them, the highest temperature in northern China will be close to 15 ° C today and tomorrow, from February 28 to March 2, the highest temperature dropped to around 6 or 7 ° C. The highest temperature in the central and southern parts of Northeast China it rose to more than 10 ℃ around the 27th, and the highest temperature will again fall below 0 ℃ in early March. For example, in Changchun, the maximum temperature will rise to 10 ° C on the 27th, reaching 10 ° C for the first time this year. After that, the temperature will drop back to -4 ° C on March 1.
The rise and fall of the temperature in the south lags behind that of the north. Today, the highest temperature in many places in the south of the Yangtze River is only around 10 ℃, and the temperature rises mainly tomorrow and the day after tomorrow, and the temperature starts to drop in early March. For example, in Changsha, the highest temperature today is 7 ° C, rising to 16 ° C on the 28th and only 11 ° C on March 1.
Also, affected by the strong cold air, the area north of the middle and lower reaches of the Yangtze River will have winds of force 4 to 6 and gusts of force 7 to 8, and local areas in the north may reach level 9 or higher. Today, strong winds appear mainly in eastern Xinjiang, western Gansu, central and western Inner Mongolia, and western North China; tomorrow they will appear mainly in Inner Mongolia and Northeast China; on March 1 it will mainly affect the south of northeast China, Huanghuai and the eastern seas. .
At the same time, there will be sand and dust in some areas. There will be floating sand or dust in parts of the eastern part of the southern Xinjiang basin in Xinjiang, western Inner Mongolia, western Gansu, Ningxia, and local sandstorms. . The impact of cold air this time can be called “omnipotent”. Rain, snow, strong wind, temperature drop, sand and dust are at stake. The public should be aware of weather changes over time and take precautions.
