6 . Several security guards of residential compounds in Beijing and workers were seen shoveling snow and some parked vehicles were covered by thick overnight snow. The first snowfall of winter arrived in Beijing early Monday, covering the Chinese capital with a mantle (披风) of white overnight and plunging (使……下降) the city into freezing temperatures, with even colder weather coming this week in northern China.
Snowfall reached 5.8 mm on average by early Monday, with the highest snowfall of 10.2 mm recorded in Fangshan district, Beijing Meteorological (气象的) Service data showed. Beijing typically sees its first snow of the season between late November and February, or even none at all. More snowfall is expected this week, with temperatures seen further sliding to as low as -20°Celsius. The Chinese capital last saw such similarly extremely cold weather on Jan. 7, 2021, when the temperature dropped to -19.6℃.
The cold snap (寒潮) in Beijing this week, compared with the autumn-like conditions a week ago, mirrored the sharp swings in temperatures recently. In October, Beijing experienced one of its warmest Octobers in decades in a year of weather extremes.
On Monday, the government warned of road icing in large parts of the city of nearly 22 million, with authorities shutting some expressways or partially closing sections. By 10 a. m. local time, 62 out of a few hundred flights had been cancelled at the Beijing Capital Airport. Railway authorities enforced speed limits on lines connecting Beijing and Guangzhou in southern China, causing delays in some passenger trains. By 7 a. m. Monday, more than 180 bus routes in Beijing had been suspended.
The official Beijing Daily reported that vegetable stocks were enough, hitting this year’s highest daily market volume of 23,800 tons, as merchants stocked up (备货) ahead of time. Huang, a Beijing resident working in the internet sector, said the snow in Beijing came early. “Normally, it doesn’t snow until the Spring Festival,” Huang said, referring to the start of the Lunar New Year, which typically falls in January or February.
