Many places in Heilongjiang have been hit by snowstorms. What are the characteristics of this cold wave weather?

This cold wave weather has four characteristics: large influence range, fast moving speed and complex weather system.

Feature 1: wide range of influence

The central and eastern parts of China, the eastern part of Huanghuai, Jianghuai and the central and eastern parts of the south of the Yangtze River have obviously cooled down, and the cooling range can reach 12 degrees. However, many places in Heilongjiang suffered from heavy snow, and there was a snowstorm in Xiang Xue on 2 1 night. Like Changsha in the south, it not only rained for several days, but also blew a strong wind at the weekend (that is,165438+1October 2 1), and the cooling rate was obvious. The highest temperature on Friday was 23 degrees, while the highest temperature on the 22nd was only 13 degrees.

Feature 2: Cold air moves fast.

The cold wave moves faster. 2 1 In the morning, the cold front is still in the north of North China, and it will affect South China at night. In this process, the moving speed of cold air is faster than the last tidal wave, which is closely related to the strong "thrust" of the middle and lower turning flow.

Feature 3: The weather system is complex.

For example, there are blizzards, big blizzards and even local blizzards in Northeast China. There is little to moderate rain in the southern region; There may be sand blowing or floating dust in northern North China. It can be said that the weather stage presents a pattern of "letting a hundred flowers blossom".

Feature 4: There are snowstorms in many places.

165438+1From October 20th, it was snowing all over the northeast, from Shenyang to Zhongxue, from Changchun to Heavy Snow, and from Harbin to Heavy Snow. Blizzard center is located in Hegang, Jiamusi and Shuangyashan. There will be two days of heavy snowstorms and heavy snowstorms, and the total snowfall will be close to that of Tongliao last time, which may be close to or break the local record 165438+ in early October.

Generally speaking, a snow typhoon is forming, which will affect the northeast region and lead to heavy snowstorms in many places. Cold wave weather has the characteristics of large influence range, fast moving speed of cold air and complex weather system.

According to the analysis of meteorologists, compared with the last cold wave process, the heavy snowfall area is eastward, and the precipitation in parts of central and eastern Heilongjiang may exceed the historical extreme value in the same period. It is reported that northern Yichun, northeastern Harbin, Hegang, Jiamusi, western Shuangyashan, Qitaihe and western Jixi will encounter heavy snow. Because snowstorms are often accompanied by windy weather, everyone needs to take precautions against snowstorms, low visibility and snow resistance in advance.
