how does hail form
How does Hail Form?

Strong updrafts of warm air and down-drafts of cold air are in a thunderstorm.

If a water droplet is picked up by the can be carried well above the freezing level. With temperatures below 32°F...our water droplet freezes.

As the frozen droplet begins to fall...carried by cold may thaw as it moves into warmer air toward the bottom of the thunderstorm may also get picked up again by another updraft...carrying it back into very cold air and re-freezing it. With each trip above and below the freezing level our frozen droplet adds another layer of ice.

Finally...our frozen water droplet...with many layers of ice - much like the rings in a tree...falls to the ground - as hail!


How Lightning Forms

The connection is made and the protons rush up to meet the electrons. It is at that point that we see lightning and hear thunder. A bolt of lightning heats the air along its path causing it to expand rapidly. Thunder is the sound caused by rapidly expanding air.



What is a tornado?

"a violently rotating column of air, pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud."

How Do Hurricanes Form?

3.Having lost most of its heat and energy, the air is now expelled outward away from the center of the storm in the cooler hurricane outflow at high levels.

In mature hurricanes, an eye forms in the center. Here, the air is descending and the region is generally cloud-free.

2. The warm, moist air rises in thunderstorms surrounding the eye, supplying the fuel that helps strengthen thestorm and intensify the winds.




1.As air rushes into the hurricane’s low pressure center, the air picks up heat and moisture (fuel) from the warm ocean surface.

A 1x4 board of wood was pierced through a palm tree by Hurricane Andrew’s winds in August, 1992.

A mobile home park near Miami, FL was completely destroyed by Hurricane Andrew in August, 1992.

An historic home along the Gulf Coast before and after the passage of Category 5 Hurricane Camille in August, 1969.
