Bell Work- Good morning Shinning Students!

• Determine if each answer is correct or incorrect
  and explain why.
• 1. The following is a process that takes place in
  the atmosphere
• solar energy?warm air rises?air cools in upper
  atmosphere and sinks?air currents
• This process can best be identified as
• F wind formation.
• G cloud formation.
• H precipitation runoff.
• J static electricity.

2
Standards

• SPI 0607.8.4
• Interpret meteorological data to make predictions
  about the weather
• SPI 0607.8.2
• Recognize the connection between the suns energy
  and the wind

Study Island

• Due December 2, 2010.
• Remember class with the highest overall average
  and the most amount of questions attempted will
  win a prize.
• Currently, 1st period is winning!
• If you have not tried to get on at home yet, you
  need to attempt this weekend and let me know
  Monday if it isnt working.

4

• What type of cloud forms when warm air rises and
  generally indicates good weather?
• What type of clouds form in layers?
• What does the word nimbo tell us is about to
  happen?

• This presentation is intended to introduce or
  review material. The student will identify each
  type of front on a weather map using their
  symbols, determine which way the front is moving,
  and predict relative temperature using a weather
  map.

Weather Fronts

• Have you ever wondered how the weather can change
  so quickly? For example, the weather may be warm
  and sunny in the morning and cold and rainy by
  the afternoon.
• Discuss with your neighbor, what causes these
  changes in weather?

8
Air Mass

• A large body of air with similar temperature and
  moisture.
• Air masses form over large land or water masses.

9
Frontal Boundaries

• Where air masses interact also know as a front.
• 4 kinds of fronts
• Cold front
• Warm front
• Occluded front
• Stationary front

10
Cold Air Masses

• Most of the cold winter weather in the U.S. is
  influenced by three polar air masses.
• Continental Polar- (cP)- is an air mass that
  forms over northern Canada and brings extremely
  cold weather to the U.S. in the winter and cool
  dry weather in the summer.

11
Cold Air Masses continued

• Maritime Polar (mP)- are air masses that form
  over the North Pacific Ocean and are cool and
  very wet.
• Brings rain and snow to the Pacific Coast in
  winter and cool, foggy weather in the summer.

12
Cold Front
Back to activity

• A cold air mass is replacing a warmer air mass.
• Shown on a weather map by a blue line with
  triangles pointing the direction the cool air is
  moving.

13
Warm Masses

• Warm Masses- there are four warm air masses that
  effect the weather in the U.S.
• Maritime Tropical (mT)- an air mass that develops
  over warm areas in the Pacific Ocean and are
  milder than mP.
• Other mT develop over the Guld of Mexico and the
  Atlantic Ocean and bring hot and humid weather in
  the summer, hurricanes, and thunderstorms.
• Maritime Polar (mP)- an air mass that forms over
  the Pacific ocean and brings cooler air

14
Warm masses continued

• Continental Tropical- (cT)- an air mass that
  forms over the deserts of northeren Mexico and
  southwestern United States.
• This mass moves northward and brings clear, dry
  and hot weather in the summer.
• Continental Polar- (cP)- form over northern
  Canada and bring cool weather

15
Warm Front
Back to activity

• Warm air mass replacing a cooler air mass.
• Shown on a weather map by a red line with half
  circles pointing the direction the warm air is
  moving.

16
Comparing Warm and Cold Fronts

• Cold fronts move faster than warm fronts.
• The weather activity in a cold front is often
  violent and happens directly at the front.
• Cold fronts have sudden gusty winds high in the
  air creating turbulence.
• The weather activity in a warm front generally
  happens before the front passes.
• In a warm front the cloud formation is very low
  often creating situations of poor visibility.

17
Occluded Fronts

• When a warm front is trapped by 2 cold fronts.
• Shown on a weather map by a purple line with
  alternating triangles and semicircles pointing
  the direction the front is moving.

Back to activity
18
Stationary Fronts
Back to activity

• A front that stops moving or is moving very
  slowly.
• Shown on a weather map with alternating red
  semicircles pointing away from the warm air and
  blue triangles pointing away from the cold air.

Be a Weather Forecaster
You are planning to travel to Alabama in 2 days.
The high temperature there for today is 68º F.
Use the map to help you predict whether the
temperature in Alabama will increase, decrease,
or stay the same. Explain why you think so.
26
Be a Weather Forecaster
There is a cold front approaching. The
temperatures will probably be cooler behind the
front.
27
Be a Weather Forecaster

• Of course, meteorologists (weather forecasters)
  use much more data than fronts and air masses to
  help them forecast the weather more accurately.
  But any forecast is just a prediction of what
  might happen. Even with the best data, weather
  forecasts can be wrong.
