是什么在云层中创造了这个巨大的X ？那是飞机尾迹的影子。当飞机飞行时，潮湿的发动机废气可能会形成水滴，这些水滴可能会在地球寒冷的上层大气中结冰。这些持续的水和冰流散射了来自上方太阳的光线，因此看起来很明亮。这些尾迹投下长长的影子。本月早些时候，土耳其伊斯坦布尔上空的情况就是如此。尾迹在地球上随处可见，通常，尾迹在捕捉红外光时使地球变暖，但在有效反射阳光时使地球变冷。这张照片是一位摄影师在早上上班的路上拍下的。

What created this giant X in the clouds? It was the shadow of contrails. When airplanes fly, humid engine exhaust may form water droplets that might freeze in Earth's cold upper atmosphere. These persistent streams of water and ice scatter light from the Sun above and so appear bright. These contrails cast long shadows. That was just the case over Istanbul, Türkiye, earlier this month. Contrails occur all over planet Earth and, generally, warm the Earth when the trap infrared light but cool the Earth when they efficiently reflect sunlight. The image was taken by a surprised photographer in the morning on the way to work.
