1. Rainbow clouds As one of the 20 most peculiar natural phenomena in the world, rainbow clouds are a very rare and beautiful cloud, formed by small ice crystals in the clouds just refracting the sunlight and then appearing as a rainbow, and in 2011 Russian mountaineer Baltunov had seen such clouds on Mount Everest.
2. Yuhata Cave Cloud This cloud is like a cloud cave in a blockbuster movie, with an overall cave hundreds of meters in diameter, which looks very shocking, mainly because it is left behind after the airplane passes through the atmosphere, and sometimes produces rain or snow.
3. Pink Flying Saucer Cloud This saucer-shaped cloud once appeared in the Apujara Mountains in Spain, when it was at sunset, so the whole of it was red with the evening sun, thus this rare phenomenon, which is actually a kind of pod cloud.
4. Jellyfish clouds These clouds appear as independent cones hanging high in the sky, and the conical clouds below look like a jellyfish swinging its tentacles, but in fact they are actually just the incarnation of rain and snow.
5. Breast cloud storms These rare cloud storms often occur after storms, and the clouds look like breast-like bulges, one after the other, often stretching for tens of kilometers, mainly due to cold air condensation.
6. Horseshoe clouds Horseshoe clouds often only appear for one minute, because of its small size, so it will soon be evaporated, in the area of more horizontal cyclones may appear more, mainly is the rising airflow met with the impact of the horizontal airflow and formed, showing a U-shaped horseshoe shape.
7. Wave clouds Wave clouds tend to form a single piece, looking like a large wave lapping at the shore, but this phenomenon will only last less than 2 minutes, and only when the wind speed is just right to form, so it is also very strange and rare.
8. Cap clouds Mountain cap clouds are shaped like a hat by name, and they mainly appear on top of mountains, which are due to the air moving too fast after thunderstorms, making the clouds appear in the shape of mountain peaks when they cross the mountains.
9. Pod-shaped clouds Pod-shaped clouds look like flaky pods and are a type of high cumulus clouds, which have appeared 2-3 times in the UK, Russia and in our country, when many people mistook them for flying saucers.
10. Rolling clouds Most of these clouds appear as a straight tube, mostly in the vicinity of storms, when the air currents expand violently downward, causing them to rotate and curl, thus creating a tubular cloud formation.
