介绍:
This is how it happens. The fires are so hot and so large that they send air extremely high in the sky, where it forms what's considered the titan of all cloud species - a Pyrocumulonimbus Cloud. This colossal fire cloud shoots up to 10 miles in the air at a hundred miles per hour and it's strong enough to produce a rainless thunderstorm. Then the clouds develop so high that they can break through the stratosphere and send particles soaring around the globe. All these elements have made the fires move even faster. The Pyrocumulonimbus Clouds are so powerful and so high that local weather no longer influences them. Even when it's raining, the smoke will continue to linger and fuel rapid fire growth. Scientists say Australia isn't likely to be an exception for long. We could see more fire clouds as climate change makes wildfires more intense and fire seasons longer. 事情就是这样发生的。火如此之烈,面积如此之大,以至于它们把空气输送到了极高的空中,在那里形成了一种积雨云,它被认为是所有云的种类中的巨人。 这种巨大的火云以每小时100英里的速度在空中上升到10英里,其强度足以产生一场无雨雷暴。之后,云层变得如此之高,以至于它们可以突破平流层,把粒子在全球范围内散播开来。 所有这些元素都使大火移动得更快。高温积雨云是如此强大,如此之高,以至于当地的天气不再能够影响它们。即使在下雨的时候,烟雾也会继续弥漫,火势也会迅速增长。 科学家说,澳大利亚的火灾长远来看会变得非常普遍。我们可以看到更多的火云,因为气候变化使野火更加强烈,火灾季节更长。
