高空的白雾带是怎样形成的? 晴空中,有时会见到一条长白带,有些人说这白带是喷气式飞机过后所形成的, 但喷气式飞机喷出的是黑烟,为什么会形成白带呢? 在晴天, 由于大气没有云层阻隔,大气的内能较容易向太空散失,故晴空的气温比阴天低.气温往往低于水汽凝结的温度.但水汽要凝结成水,必须有固体微粒作为核心,正如同尘埃是雾的核心一样. 当喷气式飞机过后,就在路程上留下大量的烟粒,这些烟粒正好成为水蒸气凝结的核心,于是就形成一道雾带.这雾带把阳光反射, 就形成光亮的白雾带了. How is the height of the white fog formed? In the clear sky, a long-term leucorrhea belt is sometimes seen. Some people say that the leucorrhea was formed after a jet plane. However, the jet plane emits black smoke. Why does it form a leucorrhea? In sunny days, because there is no cloud cover in the atmosphere, the internal energy of the atmosphere is easier to dissipate into space. Therefore, the air temperature in clear air is lower than that in cloudy days. The temperature is often lower than the temperature of vapor condensation. However, water vapor must be condensed into water and solid particles must be used as The core, just as the dust is the core of the fog. When the jets passed, they left a lot of smoke particles on the way. These smoke particles just became the core of the condensation of water vapor, so they formed a fog belt. The sun reflects, forming a bright white fog.
