霸王寒流來襲 東北亞急凍

 A cold mass from the North Pole hit Asia. South Korea, Japan and China registered record low temperatures. Seoul experienced the strongest cold spell in 35 years, with the mercury dropping to minus 18.6 degrees. The Han River began to freeze. To secure a safe route, the officials had to use an icebreaker ship.
 In Japan, unusual cold weather led to a high electricity demand. Peak electricity demand in the country was about 90% more than expected supply. To prevent a nationwide blackout, the authorities have called on the public to use less power. A power outage could further damage the economy already struggling with another wave of the coronavirus pandemic.
 China’s Central Meteorological Station released the first cold warning in 2021 to several regions. Cities such as the eastern port city of Qingdao recorded the lowest temperature in history and the capital city Beijing had its coldest day since the 1960s on Jan 7th.
 The extreme cold wave was attributed to a negative Arctic Oscillation, which is a climate pattern that influences weather in the Northern Hemisphere. A very strong ridge of high pressure allows cold Arctic air to slide south.

 來自北極的冷氣團襲擊亞洲,使南韓、日本、中國等國家的氣溫創下歷史新低紀錄。首爾經歷了三十五年來最強的寒流,溫度降至零下十八點六度,漢江也開始結冰了。政府官員因而出動破冰船,確保行車能安全通過。
 在日本,異常寒冷的天氣導致電力需求大增。全國高峰期的電力需求比預期供應量多出約百分之九十。為了防止全國性停電,當局呼籲民眾節約用電。如果全國停電,可能使日本受新一波新冠疫情衝擊的經濟更加惡化。
 中國中央氣象站針對幾個地區發布了二○二一年的首次低溫警告。青島等東部港口城市記錄到史上最低溫;一月七日成為首都北 京自一九六○年代以來最冷的一天。
 這波霸王級寒流可歸因於影響北半球天氣的氣候模式「負北極震盪」所生成的一個非常強大的高壓脊,使北極冷空氣向南滑動。
