Why Is It Colder Up There?

Why Is It Colder Up There? Miso and his father are flying from Korea to Canada. Miso is very excited. On the back of the seat, there is a small computer screen. It shows the path the jet is taking and how fast it is travelling. It also shows the temperature outside. Miso notices something really strange. The temperature outside the jet is-55℃. That's really cold. “ When we left Seoul it was nearly +25℃, ” thinks Miso. “ How can this be?” So he asks his father a question. " In this jet, we are closer to the sun. Shouldn't it be much hotter because we are closer to the sun?Why is it colder up here?"

为什么高空更冷? 米索和他的父亲正从韩国飞往加拿大。米索非常兴奋。在座位的后面，有一个小的电脑屏幕。它显示了飞机的飞行路线和飞行速度。它还显示了外面的温度。 米索注意到一件很奇怪的事。喷射机外的温度是55度。这是非常冷。 “当我们离开首尔时，气温接近+25摄氏度，”米索想。“这怎么可能?” 所以他问了他父亲一个问题。“在这个喷射流中，我们离太阳更近。我们离太阳更近，地球不应该更热吗?为什么这里更冷呢?”

Father smiles. “ The ground is very good at taking in the heat from the sun, " he explains. " The sun heats up the ground, which then slowly lets go of the heat. But we are many miles above the ground now in this jet. The heat from the ground cannot reach us here. " Miso has learned something interesting today.

父亲的微笑。他解释说:“地面非常善于吸收太阳的热量。”“太阳加热了地面，然后慢慢释放热量。但我们现在在离地面很多英里的飞机上。地面的热量无法到达我们这里。” 米索今天学到了一些有趣的东西。
