Understanding the process behind hail formation reveals the raw power and dynamics of these atmospheric phenomena. First, it should be noted that not all thunderstorms are capable of producing ...

Wind shear — a change in wind speed and direction at varying altitudes — can help to encourage large hail formation. But research suggests climate change is causing wind shear to diminish ...

There are two methods of hail stone formation and growth that give hail stones their "layered" look. A tiny ice crystal will be the nucleus of the hail stone. In wet growth, supercooled water ...

NARRATION: It takes very special conditions to create a hailstone. You need summer thermals, and you need a violent thunderstorm. Because of the height of thunderclouds some of the water droplets ...

The impact of hailstorms on different parts of Australia varies year to year, but a Bureau of Meteorology research scientist says there's a southward trend with the warming climate.

Urban landscapes and man-made aerosols have the potential to accelerate the formation of hail storms, according to a recent study by the U.S. Department of Energy’s Pacific Northwest National ...
