黑龙江漠河-43.5℃现冰雾 游客大玩“泼水成冰”
Rare ice fog gripped the Chinese city of Mohe in the north of the country after temperatures suddenly dropped to a bitter -43.5℃ on December 6, according to Chinese media. The Mohe authority announced that temperatures fell to minus 41.1 degrees Celsius on Tuesday, minus 42.1 on Wednesday and minus 43.5 on Thursday.
A cold front approached the northern city on Monday, causing temperatures to drop by between 12 and 20 degrees Celsius. Authorities were forced to issue the city’s first-ever red warning for cold weather. The Heilongjiang Meteorological Bureau also issued an orange warning for cold weather.
Visibility was reduced to less than 100 meters, which made driving difficult, but the conditions did not decrease the spirits of some brave tourists, who went outside to witness the meteorological phenomenon and have fun. Videos on social media showed people throwing water into the freezing air, causing it to turn to ice immediately.
Ice fog only occurs in the world’s coldest regions, as drops of water staying in air can remain in liquid form down to temperatures as low as minus 40 degrees Celsius. It is a phenomenon regularly witnessed in the Arctic and Antarctic, but can also form at extreme northern and southern latitudes, in regions including Alaska and northern Russia.
Mohe is located in the Heilongjiang Province bordering Russia, and is the northern city in the country. The city is often referred to as “China’s Arctic town”, and is one of the few locations in China to have such climate. Winter in the city begins in early mid-October and lasts until late April, and average temperatures stay below freezing for about seven months of the year.
