Starting from the night of the 15th, the Northeast region ushered in the third rainy and snowy weather event this month. The Central Meteorological Observatory issued an orange blizzard warning on the 16th.

It is expected that from 8:00 on the 16th to 8:00 on the 18th, there will be heavy snow in some areas of central and eastern Heilongjiang and central and eastern Jilin. There will be heavy snow in some areas of eastern Heilongjiang and central Jilin. There will be local heavy snow or extremely heavy snow. There will be new snow accumulation in some of the above areas. Depth 10 to 18 cm, locally more than 20 cm. The main period of this round of snowfall is from the daytime of the 16th to the 17th.

“Since the snow depth in some areas of central and eastern Heilongjiang and central Jilin has reached 20 to 30 centimeters in the early stage, and locally reached 40 centimeters, although this round of snowfall is dominated by wet snow, it is expected that the snow depth will still increase significantly. There is a significant superposition effect between the falling area and the previous period.” Fang Chong, chief forecaster of the Central Meteorological Observatory, said that before the arrival of rain and snow, the surface temperature in some areas of northeastern Heilongjiang showed a sharp rise, so the rain and snow phase in the later period of this snowfall will be more complex. Multiple rain and snow transitions are possible.

Since November, there have been two rain and snow weather events in the Northeast. Among them, heavy rain and snow occurred in the Northeast and southeastern Inner Mongolia from the 5th to 6th. The daily precipitation at 41 national weather stations in Jiamusi and Wuchang in Heilongjiang, Hunchun and Yanji in Jilin, and Shenyang in Liaoning exceeded the local historical extreme value in November.

Meteorological experts reminded that the snowfall intensity in Heilongjiang, Jilin and other places during this round has been heavy, and there have been varying degrees of snow accumulation in the early stage, increasing the risk of disasters. The public needs to pay attention to the adverse effects of snowy, icy and slippery roads on traffic, and also needs to do a good job in reinforcing temporary structures and dilapidated houses. In addition, the temperature is low after snow, so the public needs to add clothes in time and do a good job of keeping warm.

The mid-term weather forecast of the Central Meteorological Observatory shows that from the 21st, strong cold air will affect most areas of China from west to east. The temperature will generally drop by 6°C to 10°C. The local temperature drop in North China and Northeast China will exceed 12°C, and some areas will also There will be rain and snow.

Experts say that although the precipitation brought by the cooling will help improve moisture conditions in the central and eastern regions, snow and cooling in the Northeast and other places will have a negative impact on agricultural production. Experts suggest that animal husbandry and facility agriculture should pay attention to the impact of strong winds and cooling, reserve feed in advance, reinforce sheds, cover them with insulation materials at night, and remove snow on shed roofs in a timely manner; northern winter wheat areas should strengthen winter wheat seedling management, and moisture-deficient areas should strengthen winter wheat seedling management and timely irrigation of late sowing areas.
