Since the night of March 14, my country has experienced the strongest sand and dust weather process in the last 10 years. At present, the time of sand and dust is not over, but tomorrow (March 19) a new “integral” cold air will appear again, or it will be offered again with strong wind, cooling, rain and snow, sand and dust. “.package”, northwest There will be a “protracted war” of sand and dust, and southern China will also be able to experience the extraordinary cooling power of cold air.
Today, the 5 provinces, autonomous regions and municipalities of my country still have floating sand or dust in many places in the north, or “mud rain”.
Since March 14, my country has experienced the strongest sand and dust weather process in the last 10 years. Sandstorms or strong sandstorms have occurred in parts of southern Xinjiang, Inner Mongolia, western Gansu, central and northern Ningxia, northern Shaanxi, northwestern Shanxi, northern Hebei, and Beijing., The sand and dust area exceeds 3.8 million square kilometers. Yesterday, there was still a large-scale sand and dust climate in North China, and some areas of Northwest China, North China, North Huanghuai, and North Hubei showed flying sand or floating dust.
△ Yesterday, there was still sand in Lanzhou and the visibility was bad.Today, some areas of eastern Xinjiang and southern Xinjiang Basin, most of Gansu, western Inner Mongolia, northeast Qinghai, Ningxia and other places still have floating sand or dust. Among them, there are local sandstorms in eastern Xinjiang.
In addition, today, the range of precipitation in the central and eastern regions of my country will expand to the north, and there will be rain or sleet in Xining, Lanzhou, Yinchuan and other places, which will have a certain positive effect on deposition. of sand and dust. However, due to the small amount of rain, I am afraid that the sand and dust cannot be completely removed, and the sand and dust fall from the sky with the rain, which will probably form a “mud shower”.
The cold air “Almighty” returns! Northwest will star in a “prolonged war” of sand and dust
According to Shi Yan, a meteorological analyst at China Weather Network, the impact of this cold air is not over yet. From tomorrow until this weekend, a new “comprehensive” cold air will appear on the scene to affect our country, and the scope of influence will be even wider, or once again We offer a “set menu” of strong wind, cooling , rain and snow, and sand. However, this time the land cyclone was not strong, and the sand emission mechanism was based mainly on the strong cold air winds that passed through the border. The dynamic conditions were significantly weaker than the previous process, and the main area of emission sand was located on the border of China and Mongolia, and the sand would not fly as high. The impact in northern China is relatively small. At the same time, rainfall and strong winds brought by cold air have an obvious cleaning effect in the current floating dust climate in North China, Huanghuai and elsewhere.
As for the northwestern region, the sand and dust process is not over yet, and a new round of sand and dust weather will follow one after another. There will be a sandy and dusty climate in southern Xinjiang Basin, western Inner Mongolia and elsewhere in the next three days. Eastern Xinjiang Strong gusts of wind can cause local sandstorms.
Rain and snow increase in Northwest China, Southwest China and South China join the ranks of cooling
In addition to the sandy and dusty climate, this cold air will also bring a wide range of rain and snow to the central and eastern regions of my country. Tomorrow, rainfall will expand rapidly to northern China and northeast China, including central and eastern Inner Mongolia. , Southeastern Jilin and eastern Tibet., Middle East Northwest China, North China North, North Sichuan Plateau and other places have mild to moderate snow or sleet. and eastern Inner Mongolia. There were light to moderate rains in parts of southern northeast China, most of northern China, most of Huanghuai, Jianghuai, Jianghan, most of Jiangnan, eastern southwest, and northern southern China .
In addition, in the next three days, the temperature in most central and eastern regions will generally drop by 4 to 8 ° C. Among them, central and western Inner Mongolia, Guizhou, Northwest Guangxi, North Guangdong, South Hunan, South Region Jiangxi and western Fujian will drop from 4 to 8 ° C. Up to 10 ℃; winds of magnitude 4-6 north of the Yangtze River, west of the Yangtze River and west of southern China, and gusts of magnitude 7-9 in northwestern China, north China and Huanghuai. The north will take the lead in cooling, especially in the eastern part of the northwest. The highest temperature in Yinchuan, Xining and other places today is still around 12 ℃, and it will drop to single digits tomorrow. With the rains, the feeling of coldness is obvious.
As the cold air deepens to the south, areas of southwest and southern China, which were continuously warm in the previous period, will also experience significant cooling this weekend. Among the provincial capitals, Fuzhou will experience a “50% reduction in temperature.” , and the highest temperature on the 20th can reach 31 ° C. The highest temperature on the 21st dropped directly to around 16 ℃.
Meteorology experts recalled that starting tomorrow, a new strong cold air will debut, and the central and eastern regions of my country will again experience significant cooling, especially in southwest and southern China, small partners can also feel the Cooling power of cold air, and everyone should pay attention to the Foresight approach, prepare the thick package in advance. In addition, the climate of floating sand and dust in northern China and the Huanghuai area will obviously improve, but in the northwest region, especially the southern Xinjiang Basin and western Inner Mongolia, it will experience a “protracted war” of sand and dust. It won’t fully improve until the 22nd. Public travel should do a good job of protecting it.
