Xiamen Daily News (Reporter Wu Xiaojing) Yesterday, many citizens of Xiamen found small white dots falling in the air, and scattered white dots drifted by in front of their eyes. Xiamen, which is located in the subtropical zone, usually only gets frost or ice in winter, but does not snow. The sight made citizens exclaim “it’s snowing”, but unfortunately, the Meteorological Department said they were likely ice crystals, or maybe even just heavy raindrops.

Snowfall is the direct condensation of water vapor in the atmosphere or the direct solidification of water droplets. For the water vapor moving in the sky to form snowfall, three conditions must be met: first, the atmosphere must contain colder ice crystal nuclei; the second is sufficient water vapor, and the air humidity must reach more than 90%, or even higher; the third is the cloud layer The temperature in the middle should drop below 0 °C, and the temperature at all levels in the low altitude should also be below 0 °C, otherwise the snow will melt during the falling process. If the cold air is quite strong and carries moisture, the temperature of 1°C to 10°C can also snow.

Meteorological expert Zhang Wei said that from yesterday’s meteorological conditions, as of 18:00, the temperature at the Xiamen National Basic Meteorological Station in Huwei Mountain fluctuated between 4°C and 8°C, and the temperature did not meet the conditions for snow, and the meteorological staff also No snowfall was observed.

So what did the public see? Zhang Wei said that from the video taken by the citizens, the small white spots may be ice crystals formed by the condensation of water vapor in the high-altitude encounter with the strong cold air. The ice crystals did not melt cleanly during the landing process. You will see the phenomenon of “sleet”. However, Zhang Wei said that the “snow” in the video could not be ruled out as an illusion caused by heavy raindrops.

The reporter learned that since the meteorological records in Xiamen in the 1950s, snowfall records have only appeared in high-altitude mountainous areas, and the snowfall concentrated in Junying Village, Lianhua Town, Tong’an. In January 2016, there was a weak snowfall process.

In Xiamen, sleet is often seen in winter. The temperature of sleet formation is higher than that of snow. Therefore, sleet can often be observed at meteorological observation sites in high-altitude mountainous areas in Xiamen in winter. It appeared in the military camp village on January 10 last year. The ground temperature in the military camp village is around 2°C.

“After 11 o’clock, I was drying my clothes on the balcony and found that the ‘raindrops’ were getting bigger and bigger, and finally it was a bit like foam floating in the air.” Ms. Wang, who lives near Xueling, recalled. Realizing that it might be “sleet”, she hurriedly took out her phone to record. Citizens also saw the same scene in Wenping Road, Wuyuanwan, Lvcuo on the island, and Crystal Lake County in Jimei outside the island.

At the same time, some citizens found that in the mobile phone weather application, the original rain sign became a snowflake pattern. The topic of “Snow in Xiamen” rushed to Weibo’s hot search list in one fell swoop.
