Pileus Clouds

The video explains the Pileus cloud, a smooth, wispy feature atop cumulus clouds, often called Cap Cloud. These clouds form when cumulus clouds grow rapidly, causing air to rise and cool, leading to moisture condensation. Pileus clouds indicate rapid cumulus growth, signaling potential weather hazards like turbulence and wind shear, crucial for pilots. They appear globally, even over wildfires and volcanoes, and can be observed from space.
