Guo Jinlan, chief forecaster at the Beijing Meteorological Observatory, said the main reasons for the heavy snowfall include low temperature in the lower layers, good auxiliary power conditions and abundant water vapor, which favors the transport of water vapor and deep layers. damp.
The Forbidden City once led the city in snowfall
In yesterday’s snowfall, the Forbidden City once led the way in the snowfall. Whenever it snows, many citizens take a special trip to the Forbidden City to enjoy the snow. Many netizens expressed that they envy the friends who booked tickets for the Forbidden City yesterday.

No obvious snowfall in the next week

Beijing launches early warning of snow and ice removal
The reporter learned from the Beijing Municipal Urban Management Committee that in response to this snowfall, Beijing launched an early warning for snow removal and an ice shovel to ensure road traffic in snowy weather. According to statistics from the Beijing Municipal Management Committee, as of 4:00 p.m. on November 21, the city had dispatched 32,158 operators and 1,894 vehicles in operation. There was no snow or ice on the urban roads.
In addition, the Beijing Municipal Urban Management Commission issued a notice to all districts, requiring that all heating units operate in accordance with the anticipated temperature rise to ensure that residents’ room temperature is above the standard temperature. 18 ° C. During the cooling period, each heating unit should strengthen the inspection of heating equipment and facilities, increase the number of maintenance personnel, and increase the frequency of measuring the domestic temperature.
The reporter learned from the transportation department that the Beijing-Kunming Expressway, the New Airport North Line, the Sixth South Ring Road, the Beijing-Taiwan Expressway, the Beijing-Hong Kong-Macao Expressway, the Beijing-Kaisha Expressway, Beijing-Harbin Expressway and Shouhuan Expressway and Expressways are all managed and maintained by the 1st Maintenance Company. It snows and ends up spreading deicing agent on every road. On the sixth ring of the Beijing-Taiwan Expressway, there is light to moderate snow, and snow melting agent will be sprayed on key areas of bridges.
■ Dispel doubts
Why is there no snow in the city?
Previously, the Department of Meteorology stated that the difficulty in predicting the snowfall process this time is the precipitation phase, because whether the snowflakes melt during the fall depends on the vertical distribution of the temperature in the sky. At present, it is the beginning of winter, and the medium and low temperature is at the critical point of conversion of the rain and snow phase. Therefore, there is a certain degree of uncertainty in predicting the precipitation phase in the plain area, and the phenomenon of rain and snow conversion may occur.
Snow fell in the city yesterday with rain. Also, the surface temperature during the day in urban areas is above 0 ° C, and the snow will melt quickly after falling to the ground and no obvious snow will form.
How many days does it snow every year in Beijing?
According to statistics, the annual average snowfall days in the Beijing Plain area is mainly 10-12 days, and the observatory representing the Beijing weather has an average of 10.8 days. Mountainous areas are more prone to snowfall than plain areas, and the average number of days of snowfall is more than 12 days. Yanqing in the mountainous northwestern area has more snow days per year, with an annual average of 16.4 days and 23.8 days at Foyeding at Gaoshan Station.
