CCTV News: According to the website of the Central Meteorological Observatory, the cold air affecting our country has been relatively active since November, and there have been two strong wind cooling processes in the central and eastern regions. Among them, the first cold wave process in the second half of the year occurred from the 4th to the 7th, and the temperature generally dropped in the north. 6-10℃, heavy rain and snow will occur in Northeast China and eastern Inner Mongolia. It is expected that a moderate-intensity cold air will affect central and eastern China from the 15th to the 17th. The intensity of the cold air will be less than that of the previous two processes (November 4th to 7th and 9th to 12th), but the strong wind and cooling weather will not will be absent, and there will be strong rain and snow weather in the Northeast.
Wind cooling forecast: From the 15th to the 17th, the daily average temperature in the northwest and most of the central and eastern regions will drop by 4 to 6°C, and the temperature in the eastern part of the Northeast will drop by more than 8°C; on the morning of the 17th, the minimum temperature line of 0°C will be located in the northern part of Huanghuai to From the southern Shaanxi front line, the minimum temperature line of 10℃ presses southward to the central South China line (southern than the current position). The above-mentioned areas are accompanied by winds of magnitude 4 to 6, with gusts of magnitude 7 to 8, and locally up to magnitude 9. Some areas of the Bohai Sea, Yellow Sea, and East China Sea have northerly winds of magnitude 6 to 8 and gusts of magnitude 9 to 11. In addition, on the 15th, there was blowing sand or floating dust in parts of eastern Xinjiang and southern Xinjiang basins, central and western Inner Mongolia, western Gansu, Ningxia, northern Qinghai, and northern Shaanxi, and there were local sandstorms.
Experts remind that the recent low temperatures in the central and eastern regions require the public to pay attention to its adverse effects on human health and energy supply. In windy weather, they need to stay away from temporary structures, billboards, etc., and pay attention to travel safety. In addition, there is sand and dust in places such as Xinjiang, Inner Mongolia and the northwest region. The public needs to take relevant protection when going out and pay attention to the impact of sand and dust on traffic.

Meteorological experts reminded that there are currently varying degrees of snow accumulation in Heilongjiang, Jilin and other places. The snow accumulation in central and eastern Heilongjiang has reached 15 to 30 centimeters. Strong snowfall will increase the risk of blizzards, low-temperature rain and snow, and the public needs to be vigilant about rain and snow. The weather may cause slippery roads, icy roads, etc., which may adversely affect traffic. Please pay attention to travel safety. At the same time, heavy snowfall can easily cause some greenhouses and livestock pens to collapse. Snow on the roofs of the sheds needs to be cleared in time, and reinforcement and cold protection and insulation work must be done.
