冷空气通过管道输送进来而暖空气则被输送出去。

Cool air is piped in and warm air is piped out.

暖空气意味着冰面会形成更多水塘，从而改变冰面的折光系数。

Warmer temperatures mean more ponds of meltwater on the ice's surface.

这种极端天气的形成是由墨西哥湾暖流活动速度减缓，从而输往欧洲的暖空气减少所致。

The coming cold is connected to the lower flow speed of the Gulf Stream, which causes it to send less warm air to Europe.

如果没有这些大量冷却的海冰，被带到北极的暖空气可以比以前更深入地渗透到内陆。

Without those masses of cooling sea ice, warm air brought to the Arctic can penetrate further inland than it ever did before.
