CNN News：炸彈氣旋暴擊美國 美東海岸地凍天寒

For millions of people on the U.S. East Coast, it’s like they’ve been hit by a category one hurricane, but this storm lashed them with cold and snow. Tens of thousands from Virginia, on down to Florida lost electricity. And in Connecticut, where the forecast called for at least six inches of snow, and winds as strong as 50 miles per hour, the state’s governor said utility crews wouldn’t be able to get power lines repaired if they fail.

對于美國東海岸數(shù)百萬人而言，他們仿佛遭遇了一級颶風，但是這場颶風所帶來的是嚴寒和暴雪。由于斷電，上萬人從弗吉尼亞轉移到佛羅里達?？的腋裰萏鞖忸A報表示，積雪深度至少達到六英寸，風力達到50英里/小時。該州州長表示，如果電力出現(xiàn)問題，電力公司工作人員無法修復線路。

Dozens of eastern U.S. cities were set to shiver under record-breaking cold. In Boston, Massachusetts, that could mean weekend temperatures dropping to seven below zero. New York City was expecting as much as 10 inches of snow, with temperatures dropping to about three degrees, strong winds and whiteout conditions forced JFK Airport to stop its flights. By yesterday afternoon, LaGuardia Airport had shut down too. In Newark Liberty Airport in neighboring New Jersey was also struggling to maintain flights.

數(shù)十個美國東部城市在破紀錄的嚴寒下開始瑟瑟顫抖。馬薩諸塞州的波士頓，這可能意味著周末氣溫將降至零下7攝氏度。紐約市預計降雪達10英寸，氣溫降至約3度，強風和暴雪天氣迫使肯尼迪國際機場停飛。到昨天下午，拉瓜迪亞機場也已關閉。在新澤西州的紐瓦克自由機場仍在努力維持航班正常飛行。

Passengers were stranded, residents were told to stay indoors and schools all over the Northeast were closed because of something called a bomb cyclone.

乘客被滯留，居民被告知在室內活動，同時東北部的所學校“炸彈旋風”也已經(jīng)停課。

JENNIFER GRAY, CNN METEOROLOGIST: Bombogenesis definitely sounds like a scary term. Now, bomb cyclone is a low pressure system that has undergone bombogenesis. In fact, storms that undergo this weather phenomenon can be rather destructive, causing a lot of damage.

珍妮弗·格雷，CNN 氣象學家：“炸彈生成”聽起來絕對是個可怕的詞。現(xiàn)在，炸彈旋風是一種迅速而劇烈發(fā)展的低氣壓。事實上，這種天氣現(xiàn)象的風暴破壞性非常大，會造成很大的破壞。

But in the meteorological sense, bombogenesis simply means a storm that drops 24 millibars within 24 hours. So, you basically have a storm that is rapidly intensifying.

但是，從氣象方面來看，“炸彈風暴”僅僅是意味著在24小時內，氣壓下降24毫巴。所以，事實上，你會經(jīng)歷一場迅速升級加速的風暴。

In this part of the world, we see these storms rapidly intensifying because you have the cold air from the North combining with warmer air coming in from the gulfstream. We see these in mid-latitudes and in the winter time, many times, we refer to these storms as northeasters. They can bring a lot of wind, rain and snow to the Northeast.

在這里，我們看到這些風暴迅速加劇，因為來自北方的冷空氣和來自灣流的暖空氣相結合。這種現(xiàn)象在中緯度以及冬天非常常見，我們將這種風暴稱為“東北暴風”。因為這種天氣會給東北部帶來很多風、雨水以及降雪。
