China News Service, Changchun, November 7th (Reporter Guo Jia) From the evening of the 6th to the morning of the 7th, the roofs, trees, fences, cars, and even the hats of elderly people in the park were covered in the "white heads" in Changchun City, Jilin Province. Snowflake.
Liu Haifeng, director of the Jilin Provincial Meteorological Observatory, introduced that this is the earliest and the largest range of rain and snow cooling in the history of Jilin Province in the past 10 years.
As of the morning of the 7th, cold waves, light to moderate snow and strong winds have occurred in most of Jilin Province.
The temperature dropped sharply from west to east, and the maximum temperature generally dropped by 8°C to 16°C, with a drop of 18°C in some places.
Under the action of strong wind, the wind chill effect is obvious, and the body temperature is lower.
According to Liu Haifeng’s analysis, it is expected that today and tomorrow will usher in the strongest period of this process. There will be blizzards to heavy blizzards and local extreme blizzards in the west. This weather process has a long impact time, wide range, complex rain and snow phases, and many types of disasters. Attention should be paid to prevent the adverse effects caused by heavy snowfall, freezing rain, cold wave, strong wind, and heavy fog.
In fact, people in Jilin were prepared for this cold wave, and there was no serious traffic congestion in Changchun, the provincial capital.
A few days before the arrival of the cold wave, the Jilin Provincial Meteorological Observatory had already given it a "trend". Many people adjusted their travel plans in time, and the traffic control department also sent additional police to strengthen its guidance.
In recent days, there has been an upsurge in replacing snow tires for cars in the local area, which is necessary for car skid prevention in winter.
In response to this cold wave, the Meteorological Department of Jilin Province has strengthened relevant services, instructing local farmers to strengthen the greenhouses, adjust the indoor temperature, and clear the snow on the roofs in time to prevent the adverse effects of extreme weather on facility agriculture.
Liu Haifeng introduced that the phase transition of rain and snow in eastern Songyuan, Changchun, Siping, Liaoyuan, and western Jilin will be complicated. There will be sleet-rain-sleet-snow successively, and freezing rain of 8 mm to 10 mm, but the intensity of freezing rain will occur. , Scope and duration are not as good as last winter.
Because of freezing rain, it is easy to cause snow or icing of power supply or communication lines.
To this end, the State Grid Changchun Power Supply Company installed anti-galloping spacers on key lines, compiled an emergency repair plan for power transmission ice coating, and formed a team of anti-icing flexible experts to ensure that the faulty lines were restored in the first time.
The Jilin Provincial Meteorological Observatory predicts that most of the province will have moderate snow and some heavy snow from the 9th to the 10th, and light snow in the central and eastern part of the 11th.
Liu Haifeng specially reminded that there will be rare blizzards in the western part of Jilin Province during this weather, which may cause snow obstruction, which will have a greater impact on traffic. Airports, railways, highways, etc. need to strengthen traffic safety management, and timely emergency control measures should be taken to reduce rain and snow. The adverse effects.
