Page "Hail" Paragraph 2

There are methods available to detect hail-producing thunderstorms using weather satellites and weather radar imagery.

Hail stones generally fall at higher speeds as they grow in size, though complicating factors such as melting, friction with air, wind, and interaction with rain and other hail stones can slow their descent through Earth's atmosphere.

Severe weather warnings are issued for hail when the stones reach a damaging size, as it can cause serious damage to human-made structures and, most commonly, farmers ' crops.
