Hail

Hail requires strong, sustained updrafts within a convective storm, capable of carrying water droplets up through freezing layers of the atmosphere multiple times. Each pass through the freezing layer adds a layer of ice, and the stone falls once it grows too heavy for the updraft to keep aloft.

• Defoliation, which reduces the plant's photosynthetic capacity
• Bruised or punctured fruit, reducing marketable quality even when the plant survives
• Broken stems or lodging in tall or brittle crops
• Wounds that can serve as entry points for disease-causing organisms

The severity of yield or quality impact depends heavily on the crop's growth stage at the time of the hail event; damage during flowering or early fruit development can affect the whole season's output differently than damage later in the season.

Some regions and seasons see more frequent convective storm activity and are therefore more hail-prone than others, but individual storm tracks are highly localized and difficult to predict precisely in advance.

• Hail netting over high-value orchard or vineyard crops
• Crop insurance to manage financial risk from hail events
• Diversifying planting timing or field locations to reduce exposure to any single storm
• Monitoring severe-weather warnings during vulnerable growth stages

Regions with frequent strong convective storm activity, such as parts of continental interiors, tend to see more frequent hail events than others, though any region prone to thunderstorms can experience hail.
