Large
hail fell in many places around the southeast yesterday with some up
around tennis ball size. So how can hail get to be so large?
Above is a picture of nickel size hail from Lauderdale county, AL.
Above is some more nickel size hail from Franklin, TN
What's important to notice about these pictures are the circles that
appear to be inside some of the hailstones. Just like how tree rings
tell you how old a tree is, hail rings tell you something similar. Hail
rings show you how many times the hail stone went up and down inside the
cloud. Each time it falls to the bottom of the cloud it melts a little,
and then the winds inside the storm shoot the hail back to the top of
the cloud where the newly melted surface is now refrozen into a
different layer. It does this over and over again until the hail becomes
too heavy fow the winds in the cloud to support it, then it falls down
to the ground.
