 In the mid-latitudes, hail forms near the interiors of continents, while in the tropics, it tends to be confined to high elevations.There are methods available to detect hail-producing thunderstorms using weather satellites and weather radar imagery.Hailstones 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 hailstones can slow their descent through Earth's atmosphere.
