The formation of pyroclastic clouds is based on the fact that as the sunlight passes through the clouds, there is enough moisture in the air in the evening, most of the light is blocked in the process of passing through the clouds, leaving only the red and orange light, and so the clouds seen by the naked eye are red and orange, which creates "pyroclastic clouds".

In the red, orange, yellow, green, green, blue, purple, the seven colors of sunlight, red light through the air layer of the greatest ability, orange, yellow, green light, followed by green, blue, purple light is the worst.

FIRE CLOUD IMPACT

Fire clouds are often seen in the western part of the sky during the summer months, especially around sunset after thunderstorms. The color of a fire cloud is usually red, and the appearance of a fire cloud signals that a period of warm, hot weather, abundant rainfall, and lush, vigorous biological growth is on the horizon.

When pyroclastic clouds appear, the sky is rendered red throughout by the setting sun, as if there is an erupting caldera dazzling below.
