It is expected that from the night of the 16th to the 18th, there will be light to moderate snow or sleet in Beijing-Tianjin-Hebei and other places, and heavy snow in northern Beijing and other places.
Beijing News Express (Reporter Wang Jingxi) According to the Beijing Meteorological Bureau, affected by high-altitude troughs and cold air, there were obvious rain and snow weather processes in Beijing from March 17 to 18. According to the Central Meteorological Observatory, the snowfall in northern Beijing and other places has reached the magnitude of “heavy snow”. Meteorological expert Zhang Mingying said that the overall temperature is high now, and even if the forecast shows more precipitation, there will not be “thick snow” like the cold winter season.
Lei Lei, chief forecaster of the Beijing Meteorological Observatory, said that the precipitation (including rainfall and snowfall) was mainly divided into two stages: sleet or light snow began in the mountainous areas in the middle of the night on the 16th, and snowfall in the urban areas occurred from noon to the evening on the 17th. The snowfall amounted to about 1 mm in most areas, and 2 to 4 mm in the northern areas; after a short interval, there was still snowfall across the city from the morning to the first half of the night on the 18th. Snowfall in most areas is 2 to 4 mm; in western and northern areas, it is 4 to 8 mm.
Lei Lei introduced that the cumulative snowfall in most areas during this snowfall was 3-5 mm, and the western and northern areas were relatively obvious, with a cumulative snowfall of 5-10 mm, and the northern mountainous area could reach 10-15 mm.
With rain and snow, the temperature dropped sharply from March 17th to 18th. The highest temperature during the day is expected to drop to 3℃~2℃, and the minimum temperature at night will drop to -1℃~-2℃. The temperature has risen since the 19th.
Looking at the forecast alone, it makes people think that the snow is coming. According to the Central Meteorological Observatory, it is expected that from the night of the 16th to the 18th, there will be light to moderate snow or sleet in Beijing-Tianjin-Hebei and other places, and heavy snow in northern Beijing and other places. Since the snowfall in some parts of Beijing has reached the level of heavy snow, will there be a thick snow accumulation like in the cold winter?
Zhang Mingying said that the precipitation in this process is relatively large in the forecast, “If these few millimeters of precipitation describe the snowfall in the cold winter season, it must be regarded as heavy snow, and the amount of snow will be very large. But now the temperature is It is relatively high, even if it snows, it is usually sleet, or mainly rain. In this way, it is difficult to form snow on the road, so there will not be a thick layer of snow on the ground.” Zhang Mingying said , Now that spring is coming, the average temperature is high, and the surface temperature is also high. Snowflakes will melt quickly when they fall. There is snow, but it is difficult to have thick snow.
In other words, Zhang Mingying believes that this weather process is dominated by the nature of sleet, and the “precipitation” in the precipitation is not all snow, but rain to a greater extent.
Meteorological experts reminded that there will be obvious snowfall from the 17th to the 18th, and there will be snow accumulation and road icing. It is necessary to prevent the adverse impact on transportation, power transmission and communication. Traffic will have an adverse impact. The public should pay attention to driving safety and road condition information when traveling. The temperature will drop sharply from the 17th to the 18th, which will bring certain pressure on the city’s heating, power supply, and gas supply. Supply guarantee work; body feels cold, please pay attention to keeping warm to prevent colds. Residents who burn coal for heating should pay attention to preventing carbon monoxide poisoning.
