Today (30th) is the first day of the New Year's holiday. The cold air reaches the central and eastern parts of China, the temperature will drop, and the air quality in most parts of North China will improve. However, the climate in some areas such as Huanghuai and Jianghan will continue, and it is estimated that it is expected to improve tomorrow. In addition, there will be more snowfall in the northeast today, and it is easy to present snow and icing on the road. The public needs to prevent it.

Qinghai Tongren, Guide, Guinan, Xinghai and Gonghe presented moderate to heavy snow. In the south, rainfall in the south of the Yangtze River and south-central China is declining, but the rains in the Sichuan Basin, Guizhou and Guangxi continue, and there is light rain in Chongqing and Guiyang.
Today, day to night, following the cold air eastward, the snowfall in the northeast and Shandong peninsula increased slightly, and the rainfall in the south was relatively large, but the intensity was very weak. The Central Meteorological Observatory estimates that there will be light snow in the northeastern part of Inner Mongolia, the north and east of the northeastern region, and the northern part of the western Sichuan Plateau from 08:00 to 31:00 on the 30th. In the meantime, the eastern part of Jilin has medium to heavy snow; the eastern part of the Yangtze River and the south of the Yangtze River, There are small to moderate rains in western China, central and eastern Yunnan, central and eastern Guizhou, eastern Hainan Island, and Taiwan; 4 to 6 winds in central Inner Mongolia, North China, Huanghuai, eastern Jianghuai, and northeastern Jiangnan; southwestern South China Sea Some of the seas have 8 winds and 9 winds.
Tomorrow, due to a new cold air, snowfall in northern Xinjiang will increase again. At the same time, snowfall in Heilongjiang and eastern Jilin will continue, and a white New Year's Day will be spent. The rain in Jiangnan is very short and will end tomorrow. Most of the regions will usher in a good year in good weather, but the air will gradually become dull.
A new cold air will be picked up on the 2nd and the temperature will rise to the new low after the New Year holidays.
Yesterday, following the cold air to continue to advance, the scale and ups and downs of cooling have been further increased. In the northwestern region, the western part of North China, and the southwestern part of the country, there are significant cooling effects, with a drop of 4-8 °C and a local temperature of 10 °C. Monitoring showed that at 14 o'clock yesterday, the cooling fluctuation of Hohhot reached 8 °C, the temperature was -2.6 °C; while the cooling fluctuation of Xining reached 13 °C, the temperature was only -5.8 °C.
Today is the first day of the New Year's holiday, and the cold air reaches the central and eastern regions. The Central Meteorological Observatory estimates that due to the influence of strong cold air, on the 30th, the central and eastern regions of China will have a temperature drop of 4-6 °C from west to east. During this period, the central and eastern Inner Mongolia, northern North China, and northeastern Jiangnan will be able to cool down. At 8 °C, some of the above areas are accompanied by 4 to 6 northerly winds.
In addition, affected by cold air, from the 30th to the 31st, the northeastern part of the Northeast and the northeastern part of Inner Mongolia will show small to medium snow. In the meantime, there is heavy snow (5-6 mm) in the eastern part of Jilin.
Affected by cold air, the temperature will rise first and then fall in the west of Huanghuai, Jianghuai, Jianghan, Jiangnan and South China. The temperature will rise by 2-6 °C yesterday, and then it will fall again this day and tomorrow. For example, Zhengzhou, Wuhan, Nanjing and other places have reached the high temperature of the recent temperature yesterday. The highest temperature is 13~14°C. At the beginning of today, the highest temperature keeps going down. At the end of the year, the maximum temperature will drop to single digits. The high level falls below the average line in late December of the year.
Now that the cold air effect is over, on January 2nd, a new cold air has arrived. Because most of the temperature during the New Year's Day has now returned to the level that should be expected throughout the year, it will cool again in 2018. Come to this winter's new low.
Meteorologists have suggested that because of the deep snow in the eastern part of Jilin, such as Changbai, Tianchi and Donggang, the impact of snow and ice on holiday travel has been added. On New Year's Day holiday, the temperature in most parts of China has declined. Traveling needs to pay close attention to climate forecasting, paying attention to adding clothes to keep warm.
Air quality in North China is improving.

This round of pollution has been the most since the winter. Heavy once.
Not only heavy pollution, but also the size of the fog is wide and wide. The central and southern Hebei, central Shandong, central and northern Susong and other places have even suffered from extremely strong fog. The visibility is less than 50 meters, which has put great pressure on the early peak. Many high-speed road sections are closed and traffic is blocked.

Beijing air quality will improve this morning, and Tianjin, Hebei and other places will improve in the afternoon, and New Year's Day. During the holidays, the atmosphere in the North China Plain is generally better, which is more conducive to travel.
However, affected by upstream transportation and local pollution discharge, some areas in the southern part of Huanghuai, Jianghuai, Jianghan and northern parts of the Yangtze River will be intensified and will be better tomorrow. In the meantime, some areas in eastern Henan, central and northern Anhui, and western Jiangsu have severe sputum.
