2 . 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.

3 . Perhaps you know northern Americans still maintain the habit of celebrating Groundhog Day when a large groundhog (土拨鼠) checks to see its shadow on February 2 and helps to predict when winter will end. But have you ever heard about how a mountain town in North Carolina uses a caterpillar (毛毛虫) known as the Woolly Worm to make similar predictions?
According to the folklore (民间传说), the amount of black on the woolly worm in autumn predicts the severity of the upcoming winter. The longer the woolly worm’s black bands (带) are, the longer, colder, snowier, and more severe the winter will be. Similarly, a wider middle brown band is a sign of a milder upcoming winter. The position of the longest dark bands supposedly indicates which part of winter will be coldest or hardest. If the head end of the caterpillar is dark, the beginning of winter will be severe. If the tail end is dark, the end of winter will be cold. In addition, the caterpillar has 13 segments (昆虫的节/段) to its body, which traditional forecasters say correspond to the 13 weeks of winter.
Scientific studies on worm forecasting are rare. American Museum of Natural History entomologist Howard Curran conducted a small trial in 1948. Having heard about the caterpillar folklore, Curran headed to Bear Mountain State Park to collect caterpillars each fall for eight years. He found that if the worms had brown markings on more than a third of their body, winters tended to be milder.
Most scientists view the folklore of caterpillar predictions as just that, folklore. “It’s a wonderful story, but I do think it was a playful trial,” says Joe Boggs, an entomologist at Ohio State University Extension who has studied woolly worms. “Curran was a real scientist. He had tons of papers published, but he never published this one — probably because he knew it wouldn’t stand up to peer review.”
Mike Peters, an entomologist at the University of Massachusetts, doesn’t disagree, but he says there could be a link between the band of a caterpillar and the severity of winter. Peters suggests that the timing of their growth and environmental conditions, such as temperature, moisture levels, and food sources, can impact the appearance of woolly worms, including their size, coloration, and band patterns. By analyzing these characteristics, researchers can potentially infer information about the weather conditions. “The band does say something about a heavy winter,” he says. “The only thing is that it’s telling you about the previous year.”

5 . You have probably eaten a hot dog, but have you ever spotted a sundog? This isn’t your pet dog napping in the sun!
A sundog is a weather event that causes two bright bursts of rainbow colored light to appear on either side of the sun. You would see them around 3 o’clock and 9 o’clock. Sundogs can be very beautiful, with a red glow closest to the sun and a white in the center. The scientific name for sundogs is parhelia, which comes from a Greek word meaning “beside the sun”.
Conditions need to be just right for sundogs to appear. Sunlight passes through high clouds that spread out like feathers in front of the sun. These clouds contain flat, six-sided ice crystals (晶体). If the crystal drifts toward the ground, with the larger face facing the Earth, light is refracted (折射). These crystals then separate the light, forming a sundog.
Sundogs can be seen during any season but are most often seen during the winter months when the sun is lower in the sky. You are also more likely to see them early or late in the day, when the sun is near the horizon. Sundogs have been spotted around the world, across North America, Europe, and Asia, at the South Pole and in the far north. Scientists have even predicted what sundogs might look like on other planets.
Throughout history, sundogs have been used to predict weather because they indicate snow or rain on its way. Some people believed that sundogs were a sign of good luck, while others saw them as a warning from God. Shakespeare described sundogs in poems as frightening.
Ready to try out your weather detective skills? First, use your hand to block the center of the sun to protect your eyes. Search for clouds in a winter sky and a circle or burst of light around the sun. Be sure to show off your sundog smarts to your friends and family — you’ll be their top dog!
