Rare ice fog gripped the Chinese city of Mohe in the north of the country after temperatures plunged to a bitter -43.5C 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 Thursday, the South China Morning Post reported.
A cold front approached the northern city on Monday, causing temperatures to drop by between 12 and 20 degrees Celsius.
Authorities were subsequently 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 for the whole state.
Visibility was reduced to less than 100 meters, but the hostile conditions did not dampen the spirits of some brave tourists, who ventured outside to witness the meteorological phenomenon.
