The central and eastern regions were cooled by strong cold air to 12℃
Since the new year, affected by frequent strong air conditioning, the central and eastern regions have continuously encountered a wide range of low-temperature rain and snow weather, and the lowest temperature and snow thickness in many places have set records.
Now, the strong cold air is coming again. According to the forecast of the Central Meteorological Observatory, strong cold air will affect the central and eastern regions from the 9th to 11th. At 18: 00 on the 8th, the Central Meteorological Observatory issued a blue warning of cold wave.

Most of the above areas have northerly winds of 4 ~ 6, and gusts can reach 7 ~ 8; During this period, the lowest temperature line of 0℃ will be pressed south to the east of Jiangnan to the northeast of Sichuan and the north of Yunnan, and the -10℃ line will be located in the northern part of North China-the eastern part of Northwest China.

Snowfall once caused hundreds of high-speed toll stations in Shandong to be temporarily closed or restricted.
In Beijing, where the passenger flow in Spring Festival travel rush is under great pressure, although there is no obvious rain and snow weather in Beijing this winter, the impact of strong wind cooling on returning tourists can not be ignored.
On the afternoon of the 8 th, the Beijing Meteorological Observatory issued a blue warning of strong winds. Due to the influence of strong cold air, it is expected that there will be northerly winds of 4 or 5 in most parts of Beijing from 9 to 11, with gusts of about 7.

During the period of Spring Festival travel rush, the temperature was generally high, with large fluctuations in cold and warm.
From February 1st, 2018, Spring Festival travel rush has been opened. What is the national meteorological situation in the 40-day Spring Festival travel rush exam?
According to the forecast previously released by the National Climate Center, the temperature in most parts of the country was high during Spring Festival travel rush this year, but it fluctuated greatly. It is estimated that, except the temperature in the northeast, northeast Inner Mongolia, south China and southwest China is lower than normal, the temperature in other parts of the country is close to normal to high, among which the temperature in the central and western Inner Mongolia, the central part of northwest China, the northwest part of southwest China and Tibet is 1 to 2℃ higher.
According to historical statistics, during the period of Spring Festival travel rush this year, it is the transition period between winter and spring, and it is a frequent period of meteorological disasters such as low temperature, rain, snow, freezing, strong wind and smog. The national average temperature is minus 0.6℃, and the average precipitation is 26.1 mm..
According to the forecast, during the Spring Festival travel rush this year, there will be more precipitation in the eastern part of Northeast China, the southeastern part of Northwest China, the southern part of Southwest China, northern Xinjiang and western Inner Mongolia, while the precipitation in most other parts of the country will be normal to less, with 20% to 50% less in southern Zhejiang, central and southern Jiangxi, eastern Hunan, Fujian and northern Guangdong, and it is less likely that a large-scale sustained low-temperature rain, snow and ice disaster will occur in the south. In addition, the meteorological conditions of air pollution diffusion are generally poor, including the deviation of air pollution diffusion conditions in Beijing, Tianjin and Hebei and the Yangtze River Delta, and the preference of the Pearl River Delta.
According to experts, compared with the same period of the year, the overall impact of weather and climate conditions in Spring Festival travel rush this year is small, but we should pay attention to the impact of staged and local weather. For example, during the period of Spring Festival travel rush, the temperature in the eastern region fluctuated greatly, so it is necessary to guard against the adverse effects of windy and cool weather on traffic and human health.
