*According to the Meteorological Observatory, since mid-December, the weather situation in China has been extremely complex, with various winter disastrous weather such as cold waves, rain and snow, low temperatures, and freezing. The temperature in the central and eastern regions is significantly low, and the precipitation process is frequent and extreme, and there is a wide range of heavy snowfall and obvious snow cover in North China and Huanghuai.
Snowfall is frequent and widespread.
Since mid-December, there has been a lot of rain and snow in our country. On the 10th-11th, moderate to heavy snow and local blizzard occurred in North China, Huanghuai, central and southern Inner Mongolia, central and northern Shaanxi, eastern Liaoning, and southeastern JilinFrom the 13th to the 16th, there was widespread snowfall, sleet or rain turning to snow in the north of the middle and lower reaches of the Yangtze River, and heavy snowfall or heavy snowfall occurred in the southeast of Shanxi, the central and southern parts of Hebei, the central and northern parts of Henan, the northwestern part of Shanxi and the peninsula.
From the 18th to the 19th, light to moderate snow or sleet, and localized heavy snow occurred in parts of Jianghuai, northern Jiangnan, Shandong Peninsula, and Liaoning. From the 20th to the 22nd, there was another blizzard or heavy snowfall in the northern part of the Shandong Peninsula, and there was a heavy snowfall in Weihai Wendeng (20 o'clock on the 20th - 20 o'clock on the 21st, the snowfall was 337 mm). In addition, freezing rain occurred in Guizhou, Hunan, northern Jiangxi, southern Anhui, eastern Hubei, central and western Henan, western Shandong, and central Fujian.
The cumulative precipitation of the above precipitation process is large and extreme. From the 10th to the 23rd, the cumulative precipitation in the central and eastern parts of Northwest China, North China, Huanghuai, Jianghuai and other places was more than 3 times higher than that of the same period in normal years. A total of 275 national meteorological observation stations across the country reported daily precipitation exceeding the historical extreme value in December.
Obvious snow cover appeared in North China, Huanghuai and other places. Affected by snowfall, the maximum new snow depth in southern Beijing, southern Tianjin, central and southern Hebei, most of Shanxi, northern Henan, northern Shandong and the peninsula is 10-20 cm, and the Shandong Peninsula is more than 50 cmAmong them, the snow depth reached 74 cm at 8 o'clock on the 22nd in Wendeng, Weihai, Shandong, breaking through the historical extreme value of snow depth in Shandong (54 cm, Wendeng, December 13, 2005).
After a period of time, the rain and snow gradually "converged". *The Meteorological Observatory predicts that precipitation will be scarce in most parts of the country in the next 10 days. The precipitation is more obvious in the northern part of Xinjiang, the northern part of Northeast China, the eastern part of Southwest China, the western part of Jiangnan and South China, with a cumulative precipitation of 5-15 mm, and more than 25 mm locally.
The average temperature in North China, Huanghuai, Northeast China and other places is the lowest since 1961.
Since mid-December, there have been three times of cold air affecting China, which occurred on the 10th-11th, 13th-16th, and 18th-21st. From the 13th to the 16th, the cold air reached the intensity of the cold wave, which was also the strongest cold wave since the beginning of winter, and the temperature in the northwest and central and eastern regions generally dropped by more than 6, and the land area of about 3.27 million square kilometers with a strong cooling of more than 10 occurred, accounting for 34% of the country's land area.
On the morning of the 17th, the temperature 0 line was located in the southern part of Shaanxi, central Hubei, northern Jiangxi, and central Zhejiang. Since the 18th, strong cold air has affected the central and eastern parts of China, and the temperature has continued to drop and maintained a significantly low trendOn the morning of the 24th, the temperature of Line 0 pressed south to the northern part of South China, the southern part of Guizhou, and the southern part of Sichuan.
In early December, the temperature in most parts of China was high, and since mid-December, under the continuous influence of cold air, it has turned from high to significantly low, of which the temperature in North China, Huanghuai, Northeast China, northern Xinjiang, Gansu, Inner Mongolia and other places is 4-6 lower than that of the same period in normal years, and the eastern part of Inner Mongolia and Heilongjiang are more than 8 lowerA total of 78 national meteorological observation stations across the country saw their minimum temperatures fall below the historical extremes in DecemberThe minimum temperature of 12 observation stations in Shanxi, Hebei, Inner Mongolia, Hunan and other places exceeded the historical extreme value since the establishment of the local stationThe regional average temperature in North China, Huanghuai, Northeast China and Inner Mongolia was the lowest since 1961.
*The Meteorological Observatory predicts that in the next 10 days, the temperature in most parts of the country will gradually rise to close to the same period of the year or higher, of which the northern part of Xinjiang, the eastern part of Inner Mongolia, and the central and northern parts of Northeast China will be 3 -5 high, and the southern part of South China and the southern part of the Qinghai-Tibet Plateau will be 1 -2 lower. The temperature in the northern region will turn higher than the average for the same period of the year from the 25th, and most of the southern areas will gradually rise to close to the same period of the year or higher than the average from the 26th.
