thunderstorms
an upward flow of air
lightning, thunder, rain, and dense clouds;
may include heavy rain, hail, and strong winds
leading edge of a mass of heavy, colder air
that is advancing
giant clouds piled on top of each other; top
spreads out in the shape of an anvil
a downward flow of air
heat released when water vapor condenses; is
the main driving energy of thunderstorms
short-lived storms with light winds; usually do
not produce violent weather on the ground
sudden and short-lived heavy rainfall that
usually occurs in a small area
any moisture that falls from clouds and
reaches the ground
balls of ice about .2 inch (5 mm) to 6 inches
(15 cm) that sometimes accompany storms

Dry thunderstorm
Thunder
Lightning
Bead lightning
Ball lightning
Microburst
Multiple-cell storms
sound heard when lightning heats the air so
strongly and quickly it produces shock waves
a storm where all raindrops evaporate while
falling and none reach the ground
infrequent; looks like a string of bright spots;
also called chain lightning
rare; looks like a bright ball and occurs near
the ground; also called globe lightning
discharge of electricity after electric charges
on particles in clouds grow large enough
winds that hit the ground, fan out, and cause
a sudden change in wind direction or speed
storms where one cell grows stronger, then
weakens while another takes over; repeats
a large, dangerous, and powerful
thunderstorm that contains a mesocyclone
an air mass in a supercell that rotates rapidly
a violent windstorm where destructive winds
swirl, often in a funnel shape, over land
