Defining a Storm
Defining a Storm
• Severe Weather Event
• What instruments did
Anthony Guillory and
other researches used to
predict and study severe
weather events?
• Draw an example of what
you think is a severe
weather event.
• Include a caption
describing the drawing
• We will be adding to our
drawing so use about half
a page.
• UAV – uninhabited aerial
vehicle

OBJECTIVE: Define a storm and other extreme weather events.
INTRO
•Check and Hand-in Missing Assignments
•Write Q&A in notebook:
• How would you define a storm, hurricane and tornado?
Defining a Storm
• “Trouble Brewing in the Earth’s Atmosphere”
• Questions:
– Describe Aerosonde.
– Why would scientists use Aerosonde to collect
weather data when they could use other
technology, such as an aircraft with crew, and
satellites?

• How does energy get to
Earth from the Sun?
• How does air pressure
affect weather?
• How does heat move and
keep Earth warm?
• Why is it important to
gather weather
intelligence?
• Electromagnetic radiation
travels through space to
Earth
• Air moves from high to
low pressure creating
wind
• Energy transfer – energy
from Sun heats the
ground and air /
greenhouse keeps Earth
warm
• Anticipate the threat of
“monster” storms.
Defining a Storm
• Storm
• Atmosphere
• Hurricane
• Storm surge
• Violent weather event
• Mixture of gases that
surround a planet or
moon
• Large, severe storm that
develops over tropical
oceans and have strong
winds over 75mph
(120kph)
• Flood of seawater that a
hurricane drives ashore
Defining a Storm
• Thunderstorm
• Supercell
• Tornado
• Brief, heavy storm that
has rain, strong winds,
lightning and thunder
• A large powerful
thunderstorm that can
create tornadoes
• Destructive, rotating
column of air with very
high wind speeds and a
funnel-shaped cloud
that touches the ground
Defining a Storm
• Lightning
• Electrical discharge from
a thunderstorm cloud
• Hail
• Large chunk of ice created
in powerful
thunderstorms
• Blizzard
• Severe snowstorm with
strong winds and heavy
snow for over a period of
days
Defining a Storm
• Drought
• Floods
• Runoff
• Long period of belownormal rainfall
• Forms when it rains a lot
and the ground cannot
absorb anymore water
• Water that cannot be
absorbed by the ground
and collects in low,
shallow areas
Defining a Storm
• Heat wave
• A period of aboveaverage temperatures
Discussion
• What factors distinguish a storm from
ordinary weather?
• What does extreme mean when describing
weather conditions?
• Have you ever experienced extreme weather?
What were its effects?
• Review: What is a hurricane?
• Review: What is a storm surge?
Critical Thinking
• With your group, list 5
characteristics that all
“monster” storms have
in common?
