The United States and parts of Canada have come out of winter to find a lingering ridge of high pressure inducing summer-like conditions. The map above shows surface temperature anomalies during March 13-19 compared to averages for those dates over the last 10 years. More than 1,054 locations set new daily high temperatures records and 627 saw new record lows.
美國和部分加拿大地區已走出冬天,來尋找揮之不去的高壓脊誘發夏天般的條件。上面的地圖顯示在3月13-19日期間的表面溫度異常,相對過去10年來在那些日期的平均值。超過1,054個地点創新的每日高溫紀錄,和627個地點看到新的低溫紀錄。

"Records are not only being broken across the country, they're being broken in unusual ways," reports NASA's Adam Voiland. "Chicago, for example, saw temperatures above 26.6° Celsius (80° Fahrenheit) every day between March 14-18, breaking records on all five days. For context, the National Weather Service noted that Chicago typically averages only one day in the eighties each in April. And only once in 140 years of weather observations has April produced as many 80°Fahrenheit days as this March," Volland wrote.
“紀錄不僅在全國各地被打破,而且它們以不尋常的方式被打破,”美國宇航局的亞當Voiland報告。 “例如芝加哥,在3月14-18日之間的每天看到溫度高於攝氏26.6度(華氏80度),打破所有5天的記錄。作為背景,國家氣象局指出,代表性地芝加哥在八十年代的四月只有一平均達到。及在140年的氣象觀測只有一次在4月,出現多達華氏80度的日子猶如這三月,“Volland寫道。

"Meanwhile, Climate Central reported that in Rochester, Minnesota. the overnight low temperature on March 18 was 16.6° Celsius (62° Fahrenheit), a temperature so high it beat the record high of 15.5°Celsius (60° Fahrenheit) for the same date," Volland added.
