Precipitating Clouds

Cloud seeding can modestly influence suitable clouds, but it cannot create rain from clear skies or end drought. Learn what evidence shows.

Learn what is graupel and how riming creates these unique snow pellets. Distinguish between hail, sleet, and frozen precipitation during winter storms.

Explore the physics of lake-effect snow and how cold air over warm water produces intense localized squalls.

Learn how does virga form when rain falls through dry air and evaporates before hitting the ground. Study the physics of disappearing precipitation.

How does sleet form when snowflakes melt and refreeze in the air? Understand the atmospheric layers that create winter precipitation and ice pellets.

Learn how do rainbows form when sunlight interacts with water droplets through refraction and reflection.

Review the March 2010 Melbourne hailstorm where golf-ball sized hail and intense rainfall caused city flash flooding.

Learn how cloud types and weather forecasting identify atmospheric stability and rain risks.

Virga rain over evaporation happens when falling rain vanishes in dry air. Learn why these streaks form under clouds and check for aviation hazards.

Learn how nimbostratus clouds bring steady rain to Australia. Identify these precipitating clouds by their dark, layered appearance and wide reach.
