*Meteorology- the study of the atmosphere which is used to predict
weather conditions.
Why is predicting weather
important?
It answ
ers questio
ns like:
“What sh
ould I wear to
day?”
Create a circle map with at least 10 reasons why it is
important to predict weather!
*Weather vs. Climate
*Is there a difference???
*Climate- long-term average of weather patterns in a particular area.
*Weather- short-term variations in atmospheric conditions.
Examples in
Arizona….
YES!!!
*Have you ever wondered how weather is predicted??

*Tools of Meteorology
*Thermometer

it works!!Draw a picture of

Pages 60-63
*Tools to measure weather*Barometer - measures air pressure
*Thermometer- measures temperature
*Anemometer – measures wind speed
*Weather balloons carry electronic equipment that measure weather conditions as high as 30km
* They measure temp, air pressure, relative humidity, wind speed and direction
*Psychrometer – measures humidity
*Radar – used to find location, movement, and amount of precipitation
*Satellites track storms and measure wind speeds, humidity, and temperatures at different altitudes
*Bell Work 2/18/151. Highlight the definition of thermometer,
barometer and anemometer in your IN (HW from yesterday).
2. What is the difference between a thermometer, barometer and anemometer?
On your desk:1. PRIDE
Card2. Pencil/Pen3. I.N.
Thermometer- An instrument that measures and indicates temperature.
Barometer- An instrument that measures atmospheric pressure.
Anemometer- An instrument that measures wind speed.
*REVIEW: Convection Currents!!Energy transfer in the Atmosphere…*Solar radiation from the __________ heats the Earth’s
surface. Through _________________, the air touching the Earth’s surface is heated. Hot air is _________ dense and rises. This movement of air causes ________________ currents to form in the atmosphere.
The movement and collisions of these air
masses causes weather!!!
*Air Masses*Air Mass- A large volume of air that has the same
characteristics, like humidity, or temperature, as the area it was formed.*Air masses are
always on the move!!
…. THINK Convection Currents!
*Movement of air masses*Let’s do a little investigating in order to determine how air
moves…
*Use your text book to define and label the following terms on the globe provided.
*Polar Easterlies
*Westerlies
*Trade winds
*Doldrums
*Horse Latitudes
Weather and Climate
Chapter 1Section 3Pages 14-19
*Let’s do one together!
Polar Easterlies- • A wind belt
formed as cold, sinking air moves from the poles northward or southward. These winds produce cold weather such as snow in North America.

*Bell Work 2/19/151. What are the characteristics of the Polar Easterlies?A wind belt formed as cold, sinking air moves from the poles northward or southward. These winds produce cold weather such as snow in North America.
2. What are the characteristics of the Westerlies?
A wind belt that flows North. It caries moist air which produces rain and snow.
3. What are the characteristics of the Trade Winds?
A wind belt that flows towards the equator. It was used by traders to move goods from Europe to America.

*Why did you draw curved lines??????
The Coriolis
Effect!
*The Coriolis Effect*The curving of the path of a moving object from an
otherwise straight path due to the Earth’s rotation.*Winds and Ocean currents

side of your IN)
*If you flush a toilet in Argentina, will it rotate the same way as it does here??

*What happens when air masses collide???
Weather!!!
*Air Masses and Fronts*Cold Air Masses in North America come from the North.
*Warm Air Masses in North America come from the South.
The two air masses meet in the middle and MIX to
create a front.
*Fronts
*Cold Front
*Warm Front

*Describe what is happening..
*Warm air is replacing cold air
*Some warm air rises over the cold air
*As the warm air rises it cools, water vapor start to condense….
*Steady RAIN which covers a large area!
*Cold air is replacing warm air
*Cold air is moving under the warm air and pushing upward
*As the warm air rises it cools, water vapor start to condense….
*Hard RAIN and THUNDERSTORMS!
*Describe what is happening..
*Jet Stream
*Narrow belts of high-speed winds.
*Reach max of 400km/h
*Do not follow regular paths
*Allows meterologists to track and locate storms
*Jet Stream
*How are Breezes created???....
*Pressure Systems!!
*Sea Breeze
*Land Breeze
*Sea Breeze
*During the DAY, air over the ocean is cooler and forms an area of high pressure.
*Air over land is warmer. As warm air rises it creates an area of low pressure.
*The cool air flows to the land, producing a sea breeze.
*Land Breeze
*At NIGHT, air over the ocean is warmer. As the warm air rises, it forms an area of low pressure.
*Air over land is cooler and forms an area of high pressure. The cool air moves toward the ocean, producing a land breeze.
*Reading a Weather Map*You may work with a partner, or
independently, to fill out the crossword puzzle.
*Use the map provided and your notes to help you uncover the answers!
*Bell Work 2/20/15
1. What type of weather occurs at a warm front?
Warm fronts produce steady rain to a large area.
2. What type of weather occurs at a cold front?
Cold fronts produce hard rain and thunderstorms.

2. Use the word “Severe” in 3 sentences
Study for Target Tests when you are finished with the bell work!
*Severe Weather Project
Tornadoes
Thunderstorms
Hurricanes
Storm Safety!
*Tornadoes
*Tornadoes*Happen in 1% of all
thunderstorms
*75% happen in US
*Avg speeds of 120-180km/h
Formation:
1. Wind moving in two directions causes a layer of air in the middle to begin to spin like a roll of toilet paper
2. Spinning column of air is turned vertical by updrafts of air in the cumulonimbus cloud
3. Spinning column of air moves to the bottom of the cumulonimbus cloud and forms a funnel cloud
4. Becomes tornado when touches ground
*Tornadoes

*Bellwork 2/24/15On your desk:1. PRIDE Card2. Pencil/Pen3. I.N.4. iPad
1. What is the difference between a funnel cloud and a tornado?
A funnel cloud is formed from a vertical column of air at the bottom of a cumulonimbus cloud. Once the funnel cloud has touched the ground it becomes a tornado.
2. What percentage of all tornadoes occur in the United States?75% of all tornadoes occur in the US.
3. How many tornadoes would you expect in a year where there were 2000 thunderstorms?20 = (2000 * 1/100)
*Thunderstorms
*Small intense weather systems that produce strong winds, heavy rain, lightning and thunder.
*Warm and moist air near Earth’s surface and an unstable atmosphere is required to create thunderstorms.
*Lightning and Thunder
*Lightning – electric discharge between positively charged area and negatively charged area
*Formed same way scuffing your feet on carpet and receive a shock
*Thunder – The sound caused by rapid expansion of air along the lightning strike.http://video.nationalgeographic.com/video/101-videos/

2. Which project are you focusing on today?
Get to work!!!!
*Hurricanes
*http://www.cleanvideosearch.com/media/action/yt/watch?v=4f45jA5UxB0
*Large rotating tropical weather system
*Speeds of wind 120km/h
*In Atlantic ocean = hurricanes
*In Pacific ocean = typhoons
*In Indian ocean = cyclones
*Most occur in tropical climates.
*Hurricanes
*Hurricane formation
*Begins as a group of thunderstorms moving over tropical ocean waters
*Winds traveling in two different directions meet and cause storm to spin.
*The Hurricane gets its energy from the condensation of water vapor and is fueled by warm ocean water.
*Warm moist air rises, water vapor condenses, and releases large amounts of energy
*Continues to grow
*Dies when it moves into colder waters or over land
*Hurricanes
*Hurricanes and twisters song: http://www.cleanvideosearch.com/media/action/yt/watch?v=iOw6ONcKk4g
