What is a cloud like a fish scale called a cloud?
Fish scale cloud, scientific name "Altocumulus translucent cloud", is a kind of medium cloud and a relatively common cloud. In translucent cumulus clouds, the thickness and shape of clouds vary greatly, and they are often oval, tile-shaped, fish-scale-shaped, or dense water-like clouds arranged in groups, rows and waves.
Semi-transparent cumulus clouds consist of tiny or supercooled water droplets and ice crystals. When the sun and the moon pass through the thin translucent cumulus clouds, they often observe the sunrise with blue inside and red outside due to the diffraction of light.
Usually, if the translucent cumulus clouds don't change much, it means the weather is fine. If the thickness of the cumulus clouds continues to thicken and gradually merge into layers, it means that the weather will change and even precipitation will occur.
cause
Fish scale cloud refers to a large-scale cloud with regular large gaps between clouds. The appearance of such clouds is a sign that the weather will clear up, and there will be clear skies in Wan Li and Wan Li for two or three days. The reason is that the cold air at high altitude sinks, breaking through the continuous clouds and forming fish scale clouds.
Cold air sinks to the ground and is heated, so the water in the air evaporates, the relative humidity decreases, the air pressure rises, and the clouds also rise, resulting in continuous sunny days. This kind of cloud usually appears in autumn. There are also signs of crisp autumn.
Clouds floating in the sky are composed of many tiny water droplets or ice crystals, some of which are mixed together. Sometimes it also contains some big raindrops and ice particles. The bottom of the cloud does not touch the ground and has a certain thickness.
More than ten kilometers from the ground, the closer to the ground, the higher the temperature and the denser the air; The higher the altitude, the lower the temperature and the thinner the air.
