Talking about the current snowfall in Northeast China

The Meteorological Observatory 165438+ issued a blue warning for cold wave and a blue warning for blizzard at 6: 00 on October 30th. The temperature in the southeast of Northeast China, Huanghuai and other places will drop by 6-8℃, and there will also be a large range of rain and snow in the north, especially in the northeast, where heavy snowfall will occur, and Heilongjiang will suffer severe freezing damage. The local area needs to be alert to the adverse effects of snow on traffic and life.

The Meteorological Observatory issued a blue warning for cold wave and a blue warning for blizzard today. It is expected that cold air will continue to move eastward today and tomorrow. It brings strong winds, cooling, rain and snow to the central and eastern regions of China.

The temperature drop in Northeast China is relatively large, and there will be heavy snow or blizzard in some areas. The Meteorological Observatory issued a blue warning of cold wave and blizzard. Cold air affects the central and eastern regions, and there is a blizzard in Heijiliao.

Look at the reaction of netizens to the cold wave news.

Meteorological monitoring shows that from yesterday to today, this cold air has cooled Xinjiang, Gansu, Qinghai, Inner Mongolia and western Heilongjiang by 6 ~ 10℃, and the local cooling has exceeded 12℃.

Heavy snow appeared in northeastern Inner Mongolia and parts of Heilongjiang. In the future, cold air will continue to push eastward, bringing strong winds, cooling and rain and snow to the central and eastern regions. 、

Blizzard and cold wave warnings continue to be issued.

Snowfall in the northeast has come again, and it is so heavy that it is snowstorm. With the continuous stealth of cold air, large areas in East China will continue to cool down.

Among them, Jiangsu, Zhejiang and Shanghai are the areas with the strongest cooling, and the temperature in some areas can reach above 10 degrees. However, these areas are mainly "cold" and there is no problem of heavy rain and snow. The strongest rain and snow weather is still in the northeast.

In the next 24 hours, there will be heavy snowstorms in northeastern Liaoning, eastern Jilin and eastern Heilongjiang.

Why is the snowfall so strong in Northeast China?

The fourth wave of cold wave appeared again this winter, and the main influence area is still in the northeast. It should be obvious to all that there is a "low-pressure system" near the northeast, which provides a certain foundation for snowfall conditions, and the water vapor is very abundant.

This snowfall has obvious similarities with previous snowfall patterns. Therefore, the northeast needs to be vigilant this year. This is not the first time that a snowfall pattern has been formed.

Of course, in addition to this factor, the formation of La Nina phenomenon this year has once again provided a foundation for the development of snowfall. Under the influence of La Nina phenomenon, cold air in China is highly active and strong. Therefore, there are still many extreme snowfall climates, which is a common situation.

What are the characteristics of this cold wave process?

The influence range of this cold wave weather process is still relatively wide, but the main force of cold air is not so strong. The cooling range, wind power and rain and snow intensity in most parts of the central and eastern regions are obviously weaker than last time. It has the characteristics of wide influence range, fast system movement speed, weak cooling range, weak rain and snow intensity and strong local snowfall.

Snowfall is still mainly concentrated in the northeast. Although the water vapor condition is weaker than last time, there is still obvious snowfall in the eastern region. The low-level water vapor conditions in North China are poor, and the cold air moves faster. Precipitation is generally small, mainly rainfall.
