Formation of hat clouds

When the steady airflow rises and crosses the mountains, the clouds will cool down and form a strange shape like a hat. There is a hat cloud on the top of the mountain, just like putting a white hat on it. The cap cloud is caused by rapid upward movement, including rapidly expanding Lei Yun anvil, volcanic eruption and even nuclear explosion. In each case, some substances will push the warm and humid gas up quickly. Brid said: "Hat clouds above thunderstorms are very common, because the air moves so fast that the airflow above them is in a state of chaos. Once the temperature drops enough to form clouds, you can see these cloud caps. "
