2. Meteorologist –
a person who studies weather

3. What is weather?
Weather is the study of conditions of the atmosphere are over a short period of time
Atmosphere conditions

4. Elements of weather:
Temperature
Precipitation (rainfall, snowfall)
Wind speed
Humidity
Cloud cover

5. Understanding surface chart symbols and the systems they show
 Low pressure area
                                    
 High pressure area
 Warm front
 Cold front
 Occluded front
 Stationary front
 Trough
Common weather symbols

6. Weather Fronts

7. Front
When two air masses meet they don’t like to mix so they form a border called a front.

8. What is a warm front?
A warm front is the transition zone where a warm air mass is replacing a cold air mass.

9. What is a cold front?
A cold front is the transition zone where a cold air mass is replacing a warmer air mass.

10. Weather: Under PressureL H

11. High and Low Pressure Systems
A blue "H" means a center of high pressure (usually calm, sunny weather).
A red "L" means low pressure (which can mean storminess). Most fronts extend from low-pressure centers.
                                                                                                                                 

12. Pressure: High and Low Pressure
Air has weight (yes it is true)
**All the air molecules in the atmosphere put pressure on our bodies.
**The higher you go the less pressure

13. Types of weather maps used everyday by Meteorologists

14. Front Map

15. Wind Map

16. Temperature Map

17. Precipitation Map

18. Radar Map

19. Satellite Map

20. Questions Why is it helpful to use different types of weather maps?
Where does weather happen?

21. Climate

22. Climate
climate is the pattern of seasonal weather that happens year after year

23. Climate Around the World… polar, tropical, temperate, cool, dry

24. Compare these two types of climate- make predictions and conclusions about the water cycle in these areas.
Tennessee
Arizona

25. Information on hurricanes

27. A storm goes through a series of stages before being classified as a hurricane.
Tropical Disturbance
Thunderstorms with light cyclonic circulation
Tropical Depression
Wind speeds between 20 and 34 knots (23-39 mi/hr)
Tropical Storm
Wind speeds between 35 and 64 knots (40-73 mi/hr)
Hurricane
Wind speed greater than 64 knots (74 mi/hr)

28. Hurricane Katrina Photographs
Things to look for:
Types of clouds
New dangerous conditions forming besides the hurricane
3. Look at the colors, shapes and height of the storm
