Hail appears only with certain types of
that involve warm moist air rising rapidly into
cold upper air which wants to sink to the ground.
The rising air cools and the moisture in the air
becomes liquid and then freezes into ice crystals.
If the air rises quickly enough,the ice crystals
in the air go higher while collecting more and
more material, turning into bigger ice balls. At
some point, the ice balls get so big that the wind
cannot hold it up any more and it falls back to
the surface. If the ice ball is big enough, it is
still frozen when it reaches the ground and this
is what we know as hail. If hailstone size is
related to the force of the rising winds, what
conditions would you expect to make bigger
Although we don't have very good conditions for
hail on the coast of California, it is an
important type of weather for many people and can
often be associated with major thunderstorms, or
even tornadoes. What do you think are some of
the problems that are associated with hail in
terms of people and their property? Have fun
studying this. Interesting topic!
