A new round of large-scale rain and snow is coming online, and cold air is coming. Why is there so much rain and snow recently? Let's discuss this issue below, hoping that this content can help friends in need.
Since February, my country has been experiencing two rounds of rain and snow. According to the weather forecast of the Central Meteorological Observatory, from February 16 to 18, the third round of large-scale rain and snow weather will come "online" that month, affecting more than 25 provinces, autonomous regions and municipalities.
According to the weather forecast of the Central Meteorological Observatory, a new round of widespread rain and snow will affect our country from the 16th to the 18th. This time, the snow will cover a wide area, including Hubei, Anhui, Jiangsu, Zhejiang and other places. , there is a change in the phase state of rain and snow.
“This round of impact affects more than 25 provinces, autonomous regions and municipalities. It has the characteristics of wide coverage, complex rain and snow phases, long rainfall in some areas, and heavy snowfall will occur in some areas.” China Wang Weiyue, climate investment analyst at Weather Network, introduced in detail.
Meteorological experts said that the overall intensity of this round of large-scale rain and snow is expected to be less than that of the rain and snow from February 5 to 7, and the rainfall phase in the north will be snow. The southern region will be dominated by precipitation, and the middle and upper reaches of the Yangtze River will be mixed with rain and snow.
The Central Meteorological Observatory predicts that from the 16th to the 18th, there will be light to moderate snow or sleet in the eastern part of the northwest region, the central and western parts of the Huanghuai River, Jianghan, the central and western parts of Jiangzhun, the northern part of Jiangnan and the northern part of the Sichuan Basin. Snow may change from rain to snow. Among them, there is snowfall in some areas in southern Gansu, southern Ningxia, southeastern Shaanxi, central and western Henan, western and northern Hubei, and southwestern Jiangsu, and there are heavy snowfall events in some mountainous areas.
From the 17th to the 18th, Jiangnan and South China will usher in widespread rainfall, with moderate to heavy rains occurring in some areas of Jiangxi, Hunan, Guangxi and other places.
The Central Meteorological Observatory predicts that snow will mainly occur in Gansu, Ningxia, Shaanxi, Henan and other places from the 16th to the 17th, and in central and northern Hubei, Anhui, Jiangsu, and northwest Zhejiang from the 17th to the 17th. 18th. Among them, Anhui, Jiangsu, northwest Zhejiang and other places changed from snow or sleet to rain again on the 18th.
Meteorological experts remind that there is significant snowfall in Gansu, Ningxia, Shaanxi, Henan, Jiangsu, Zhejiang and other places. People need to prevent the adverse effects of snow, snow thawing and low visibility on urban traffic, and scientifically arrange their outing time.
The total rainfall in some areas of Jiangnan and South China is relatively heavy, and people need to prevent adverse effects on transportation and local disasters.
Among the provincial capital-level cities, both Taiyuan and Hohhot can see pure snow. Among them, Hohhot has the longest snow time, lasting for nearly 2 days; the rainfall patterns in Xi'an, Hefei, Nanjing and other places All will vary between precipitation and sleet. From the 17th to the 18th, as the cold air moves southward, Nanchang, Guangzhou and Hangzhou will experience moderate to heavy rains one after another. Since February, my country has suffered two rounds of large-scale rain and snow. Not only is the intensity of the precipitation strong, but the scope of the impact is also very large.
Why are there so many rainy and snowy weather events in our country recently? "This is also because strong cold air has appeared recently, coupled with the relatively active south branch trough, the southwest warm and humid air flow in front continues to transport water vapor to the north, providing sufficient water vapor conditions for rainfall." Wang Weiyue said.
Looking forward to the mid- to late-term future, the rain and snow in the northern region is expected to subside this Sunday, but the southern region still has frequent rainy weather and low temperatures. We need to be careful about the adverse effects of ultra-low temperature freezing weather on transportation.
From February 20th to 22nd, rain and snow will continue to occur in the eastern part of Southwest China, Jianghan, Jiangzhun and most of the southern areas, so we need to remain vigilant.
