From today (December 28) to 31, the cold snap will affect most of the central and eastern regions from west to east and north to south. The Central Meteorological Observatory updated this morning and issued the first orange cold wave warning this winter. This cold wave round features the characteristics of fast moving speed, intense temperature drop and long duration strong winds. The local temperature drop exceeds 16 ° C, and the wind chill effect is obvious. Most of the central and eastern regions will successively pass the coldest period this winter. Among them, the range of rain and snow is the widest today and tomorrow, with heavy snowfalls in parts of Shaanxi, Henan and Shandong.
Most of the central and eastern regions will experience the coldest period this winter, with local temperature drops of more than 16 ° C.
Yesterday, for most of the central and eastern regions, rising temperatures remained the main concern. However, the latest round of cold weather in 2020 has been “online” and started in northern Xinjiang.
Today, the areas affected by the cold snap are mainly in Xinjiang, Gansu, Ningxia, Shaanxi, and northern northern China. As the saying goes, the temperature rises and falls sharply. Tomorrow, as the main body of the cold wave rapidly expands to the south, the area of strong wind and intense cooling will cover all the central and eastern regions. , The place found a violent cooling above 16 ℃.
In response to this, the Central Meteorological Observatory improved and issued the first orange cold wave warning of this winter this morning, which is also the highest level of cold wave warning and the first to be issued in the last four years. From 28 to 31, the temperature in most of the central and eastern regions is expected to decrease by about 10, and the temperature in the eastern part of the northwest region, the southeast part of the northeast region, the western and northern parts of North China, southern Huanghuai, Jianghuai, Jiangnan and central and northern southern China will decrease by 12-16 ℃, the local temperature may reach more than 16 ℃. The aforementioned areas will have north winds of magnitude 4 to 6 and gusts of magnitude 7 to 9, and the maritime areas of eastern and southern China will have north winds of magnitude 7 to 9 and gusts of 10 to 11; After the temperature drop, the 0 ℃ line of the lowest temperature will press south to the northern part of southern China, and the lowest temperature -10 ℃ will be from the lower reaches of the Yellow River to the mountains Qinling.
The whole cooling process is very fast. After cooling, the temperature in most of the central and eastern regions will be the lowest since this winter, and the highest temperature in Jinan, Zhengzhou, Nanjing and other places will break the freezing point for the first time. The northern part will experience the coldest period of winter the day after tomorrow, and record low temperatures in Jianghuai, Jianghan and Jiangnan will be concentrated on the 30th and 31st.
Compared to the previous “Double Twelve” cold wave, the year-end cold wave surpassed the previous one in terms of the extent of the impact and sharp drop in temperature. The maximum temperature drop in the southern region was more evident. To continue through New Year’s Day, everyone needs to be geared up in the thickest winter gear and keep warm when heading out.
Today and tomorrow, the range of rain and snow is wider, and some areas like Shaanxi and Henan will have heavy snowfall.
Yesterday, the cold wave had not gone south and the rain and snow were still scattered throughout the country. Today and tomorrow, as the cold snap continues to “deliver goods”, rainfall will spread over a large area in the central and eastern regions.
The Central Meteorological Observatory predicts light to moderate snow or sleet today in parts of the mountainous areas of southern and western southern Xinjiang, western Tibet, the central and eastern regions of the northwest, most of northern China, Huanghuai, the west and north of Jianghan and other places. There were heavy to heavy blizzards in parts of the Qinling Mountains of Shaanxi, Henan, and central Shandong; Light to moderate rains occurred in parts of eastern southwest, eastern Jianghan, Jianghuai, western and northern Jiangnan, western and northern Guangxi.
Tomorrow, there will be light snow or sleet in Huanghuai, Jianghuai, North Jiangnan, Jianghan, Southeast Northwest China, Northwest Guizhou and other places, including parts of East Shandong, North Jiangsu, North Anhui, Northwest from Hubei, South Shaanxi and other places. There is moderate snow and heavy snow in the area. There were light rains over most of the southern Yangtze River, the western and northern parts of northern China, the eastern part of southwestern China, and the eastern part of the island of Taiwan.
Due to the rapid advance of the cold wave, the precipitation in various places is relatively “soft” from rain to snow, but the whole precipitation process is also very fast, and the precipitation time in the same place can be even less than one day. The day after tomorrow, this widespread rain and snow will end quickly, and most of the country will usher in good weather.
Meteorological experts recalled that although the intensity of rain and snow caused by this cold snap process is not as strong as the “Supreme Lord” cold snap in January 2016, the relevant departments and the public in the Central and eastern regions, especially Henan, Hubei, Jiangsu and Anhui, still need to pay attention to avoid the adverse effects of snow on roads and icing on traffic.
