EXTREME WEATHER EVENTS
A change in the long-term weather patterns that characterize the regions of the world.
What is Global climate change?
What is a Jet Stream?
A very strong wind that blows high in the Earth's atmosphere and has an important influence on the weather.
A weather forecaster?
What is a meteorologist?
Most of the ocean is liquid water, but if it gets cold enough, it turns to solid ice, or if it gets hot enough, it can pass into the atmosphere as water vapor.
The temperature of the ocean determines what form the water takes.
What is Ocean temperature?
A violently rotating column of air extending from the base of a thunderstorm down to the ground.
What is a Tornado?
includes unexpected, unusual, unpredictable, severe or unseasonal weather; weather at the extremes of the historical distribution.
What is an Extreme Weather Event?
Why are Jet Streams important to local weather?
Because they contribute to worldwide weather patterns and as such, they help meteorologists forecast weather based on their position.
Special balloons that have a weather pack on them that measures temperature, air pressure, wind speed, and wind direction in all the layers of the troposphere.
What is a Weather Balloon?
Generated largely by wind. Patterns are determined by wind direction, Coriolis forces from the Earth's rotation, and the position of landforms that interact with the currents.
What is ocean surface currents?
Are formed over the Northwest Pacific Ocean.
What is a Typhoons?
Examples of extreme weather events.
(NAME AT LEAST 3)
High winds, hail, excessive precipitation, and wildfires are forms and effects of severe weather, as are thunderstorms, down bursts, tornadoes, waterspouts, tropical cyclones, and extra tropical cyclones.
What do jet Streams follow?
Jet streams follow the boundaries between hot and cold air.
An instrument measuring atmospheric pressure, used especially in forecasting the weather and determining altitude.
What is a barometer?
When they reach populated areas, they usually bring very strong winds and rain which can cause a lot of damage.

What is:
Tornadoes, Typhoons, Monsoons, cyclones, hurricanes
Are tropical storms that form over the North Atlantic Ocean and Northeast Pacific.
What is Hurricanes?
Fav science teacher???
Hey...be honest now...
Mrs. Kloke or Mrs. Logeman, or Mr. Coolon, Mr. Kenny
Which two hemispheres are the strongest for Jet Streams?
Jet streams are the strongest for both the northern and southern hemisphere winters.
How often are meteorologists correct?
Weather forecasts are correct about 80 percent of the time overall.
A warm ocean current of variable intensity that develops after late December along the coast of Ecuadorand Peru and sometimes causes catastrophic weather conditions.
What is El Nino?
The atmosphere cools in response to the cold ocean surface, and less water evaporates. The cooler, dry air is dense. It doesn't rise or form storms, they reflect the two end points of an oscillation in the Pacific Ocean.
What is El Nino and La Nina?
Connect extreme weather events with global climate change.
(in your own words)
[IMPORTANT]
A changing climate leads to changes in the frequency, intensity, spatial extent, duration and timing of extreme weather and climate events, and can result in unprecedented extreme weather and climate events.
Where is the polar jet located?
The 50°-60° N/S region is where the polar jet located.
What are the different tools that meteorologists use to predict weather?
(NAME AT LEAST 3)
(NAME 5 OR MORE FOR BONUS 500 POINTS)
Barometer, Weather Balloons, Thermometer, anemometer, Weather Satellites, Computer Models, etc...
A cool ocean current that develops off the coast of Ecuador and Peru.
Hint: Sometimes following an El Niño but causing nearly the opposite extreme weather conditions.
What is La Nina?
Are formed over the South Pacific and Indian Ocean.
What is a Cyclone?
