全球变暖导致北极附近出现极其罕见的雷暴

Giant thunderstorms so big you can see them from space have sparked fears over a warming Arctic.

从太空中都能看到巨大的雷暴，这引发了人们对北极变暖的担忧。

Nearly 50 rare strikes occurred within 300 miles of the North Pole, a spot hardly known for its lightning.

近50次罕见的袭击发生在离北极300英里的地方，一个几乎看不到闪电的地方。

They’re thought to be the result of July’s record-breaking heat, which took a particularly hard toll on Earth’s Arctic region.

这种结果普遍认为是由7月破纪录的高温造成的，这对地球北极地区造成了特别严重的影响。

Scientists at the US National Weather Service detected multiple strikes on Aug. 10 over a remote region of the Arctic Ocean.

8月10日，美国国家气象局的科学家在北冰洋的一个偏远地区，发现了多次袭击。

“This is one of the furthest north lightning strikes in Alaska forecaster memory,” the weather service, which is based in Fairbanks, Alaska, said in a statement.

位于阿拉斯加州费尔班克斯的气象局在一份声明中说：“这是阿拉斯加州气象预报员有史以来预报最远的北方雷击之一。”

While summer lightning strikes do occur in the Arctic, they are extremely rare. That’s because the air is normally too cold and dry for major storm clouds to form.

虽然夏季的闪电袭击确实发生在北极，但它们非常罕见。这是因为空气通常太冷和干燥，无法形成大的风暴云。

Yet over the weekend, the icy region saw 48 individual lightning strikes within 300 miles of the pole, with more than 1,000 hitting within 600 miles of the pole, according to National Geographic.

然而，根据国家地理杂志的报道，上周末，冰层地区在离北极300英里的范围内有48次雷击，在离北极600英里的范围内有1000多次雷击。

Thunderstorms are most common over Central Africa and other scorching tropical regions.

雷暴在中非和其他炎热的热带地区最为常见。

Climate scientist Daniel Swain dubbed the Arctic strikes “pretty wild” in a series of tweets Sunday.

气候科学家丹尼尔·斯温在周日的一系列微博中称北极雷击“相当疯狂”。

“It’s very hard to get deep convective clouds in the polar regions (especially in the vicinity of Arctic Ocean waters that used to be ice-covered, even in summer),” he tweeted.

他在推特上说：“在极地地区(特别是在过去被冰盖覆盖的北冰洋水域附近，即使是在夏天)，也很难形成深层对流云。”

A recent Arctic heat wave has wreaked havoc in the region and is thought to be responsible for the weekend’s storms.

最近，北极热浪在该地区造成了严重破坏，被视为是造成周末风暴的主要原因。

Scientists reckoned July 2019 would be Earth’s hottest month ever with record-breaking heat waves singeing the Northern Hemisphere.

科学家估计2019年7月将是地球上最热的一个月，北半球将出现创纪录的热浪。

No single event can be tied directly to climate change, but our warming planet is increasing the likelihood of Arctic storms, scientists said.

科学家们说，没有任何单一的事件可以直接与气候变化挂钩，但是我们这个变暖的星球正在增加北极风暴发生的可能性。

Arctic ice is retreating at a rapid pace, with spots in Greenland recently seeing huge ice loss and even raging wildfires.

北极冰层正在迅速消退，格陵兰岛的一些地方最近出现了大量的冰层流失，甚至是野火肆虐。

Vanishing ice makes lightning strikes more likely as it leaves more water exposed to the sun, National Weather Service weather expert Alex Young said.

美国国家气象局气象专家亚历克斯·杨说，冰的消失使更多的水暴露在阳光下，从而使闪电更有可能发生。

“The probability of this kind of event occurring would increase as the sea ice extent retreats farther and farther north in the summertime,” Young told Wired.

杨告诉《连线》记者：“这种事件发生的可能性，会随着夏季海冰范围逐渐向北退得越来越远，而越来越多。”
