Every area across the globe has its own share of storms that bring dangerous weather hazards. One of the most destructive weather-related phenomena is hail. If you live in an area with heavy thunderstorms, you have probably experienced a hailstorm at some point. It's a pretty common occurrence in areas that experience severe weather year-round, like the Midwest and the Great Plains regions of the United States.
Just like snow or rain, hail is also a form of precipitation - however, hail is solid ice that forms inside thunderstorm updrafts. In severe cases, hail can damage property and homes, leading to millions of hail-related insurance claims every year. It's helpful to understand how this dangerous weather hazard comes about, so you know what to do when hail begins to fall. Keep reading to learn more about how hail forms.
What conditions does hail form?
It is a common misconception that hail forms on the ground, but it actually begins to form up in the air inside thunderstorm clouds. A hailstone begins life as a small drop of water in a thundercloud. A thunderstorm is a cloud that makes lightning, right? Well, when you see lightning shooting up into the clouds, believe it or not, there is actually water inside that cloud.
More than 98 percent of hailstones observed have been from cumulonimbus clouds. They are dense, towering vertical clouds that typically form from water vapor condensing in the lower troposphere that builds upward carried by powerful buoyant air currents - also known as thunderclouds.
Hail is formed by updrafts inside these large cumulonimbus clouds, which carry droplets upwards to 13km - 20km above sea level. The updrafts are present at the base of these clouds and rising quickly, almost horizontally through the cloud. In the right conditions, this updraft can develop into a "supercell", which drastically increases its potential for creating large hail. These supercells form when the environmental winds change direction and speed - usually due to the formation of mountain ranges nearby or different air masses combining. The temperature difference between these two different air masses is what gives the storm its ability to create hail.
As the cloud continues to grow, water droplets freeze. And, as updrafts from the storm push up, these frozen water droplets are swept up with it. Additional layers of ice form each time the frozen water droplet is swept upwards. The frozen droplet forms into a hailstone, which continues to grow larger and heavier as more water freezes onto it each time it is swept upwards. These pellets then continue to rise through the cloud. A hailstone will pick up speed as it moves higher within the thunderstorm, and it gains enough momentum to be carried upward towards the top of a severe thunderstorm (where the air is coldest). Eventually, the weight exceeds the force of the updrafts and the hailstone falls to earth.
As they get closer to the ground, warmer air surrounding the freezing cold ice particles evaporates some of the water surrounding them. This causes a steep drop in temperature which results in the freezing cold ice particles colliding with each other, resulting in a hailstone.
A lot of times, these hailstones are rather small, measuring roughly an inch or two – but they can definitely be much larger. The longer hail is up in the air, the bigger it grows and the more damage it can potentially cause. Some hail stones can reach the size of a softball before dropping to Earth.
