Hail (
鍐伴浌
) is solid precipitate (
娌夋穩鐗?/p>
) that forms within thunderstorms. Hailstones are sometimes
found containing sand, leaves, nuts and insects. There are even reports of hail containing small turtles, baby
crocodiles and frogs! All of them have been sucked into the storm by tornadoes and subsequently enveloped
in ice through repeated updraft currents (
涓婂崌姘旀祦
).
Hailstones generally begin forming as seeds of small frozen raindrops or soft ice particles known as
graupel (
闆父
). If graupel falls through the cloud and gets into an updraft part of a thunderstorm, it mixes
with
water
drops
and
ice
particles
that
will
freeze
around
it
as
it
rises,
like
layers
of
an
onion.
These
ice-
stones are carried into the tops of the cloud, gaining mass as they rise. Somewhere up there, they become
too heavy for the updraft to carry and so fall towards the ground. As they fall, the outside layer melts to a
