How to Make Ice Spikes in your Freezer. How to Identify Severe Thunderstorms on Radar. Several conditions are required in the atmosphere in order for hailstorms to occur. Highly developed Cumulonimbus clouds need to be present. These are the massive anvil or mushroom shaped clouds that are seen during thunderstorms which can reach heights up to 65, feet. There must also be strong currents of air ascending through these clouds. These currents are commonly known as updrafts. The updrafts contain ice particles, as a large number of water droplets become solid ice at the low temperatures found at high altitudes within the massive clouds.
The last remaining condition is that the clouds will need to contain high concentrations of supercooled liquid water. Text on this page is printable and can be used according to our Terms of Service.

It differs from climate, which is all weather conditions for a particular location averaged over about 30 years. Weather is influenced by latitude, altitude, and local and regional geography. It impacts the way people dress each day and the types of structures built. Explore weather and its impacts with this curated collection of classroom resources.
Catastrophic weather events include hurricanes, tornadoes, blizzards, and droughts, among others. As these massively destructive and costly events become more frequent, scientific evidence points to climate change as a leading cause. While they can often be predicted, the loss of life and property take an emotional and economic toll on the community impacted.
Explore these resources to teach your students about catastrophic weather events and how they impact every part of the world. The environmental hazards you face depend on where you live. For example, if you live in northern California you are more likely to be impacted by a wildfire, landslide, or earthquake than if you live in Charleston, South Carolina, but less likely to be hit by a hurricane.
This is because the physical conditions in each place are different. The active San Andreas fault runs through California and causes regular earthquakes, while the warm waters transported by the Gulf Stream can intensify a storm heading for South Carolina. These environmental hazards shape human activity regionally. Learn more about environmental hazards with this curated resource collection.
Toss supercooled water into an updraft of air within a thundercloud and what do you get? A hailstorm! Cloud cover is an important component of understanding and predicting the weather. Not only does cloud cover impact sky conditions and inform precipitation predictions, it also helps regulate the temperature that occurs in a region.
