1. Weather Review Atmosphere in Motion

2. Winds blow from _____ pressure to _______ pressure.

3. Winds blow from High pressure to Low pressure. They also blow from COLD to WARM air

4. How would you describe the winds in the NE section of the US?

5. How would you describe the winds in the NE section of the US? HIGH WHY?

6. How would you describe the winds in the NE section of the US? HIGH WHY? Isobars are very close together indicating large change in pressure

7. Remembering that winds are named by the direction from which they come, which one of these is a land breeze? A B

8. Remembering that winds are named by the direction from which they come, which one of these is a land breeze? B is a land breeze. Explain why. A B

9. Remembering that winds are named by the direction from which they come, which one of these is a land breeze? B is a land breeze. Because the land cools off very quickly at night, while the ocean temperature stays basically the same. Since Winds blow from cool to warm, the breeze at night comes from the land. A B

10. Remembering that winds are named by the direction from which they come, which one of these is a land breeze? A is a sea breeze. During the day, the land heats up much more quickly than the water, and therefore, since wind blows from cool to warm, the breeze comes from the water. A B

11. Air movement Put: conduction, convection and radiation in order of how air masses are formed. (Describe a convection current)

12. Radiation – heats up the land Conduction – heats up the air Convection – moves the warm air around

13. Draw a cold front and describe the associated weather

14. Cooler temps, rain, storms Cold dry air collides with warm moist air

15. Draw a warm front

16. Warm air rises up and over the cooler more dense air

17. List the four terms associated with describing air masses

18. Maritime – moist Continental – dry Polar – cool/cold Tropical – warm/hot

19. Name the air mass that would form over the Gulf of Mexico

20. Maritime Tropical = warm and moist

21. Explain why coastal climates are cooler in the summer and warmer in the winter

22. Water does not heat up or cool down as fast as land, so the sea breezes near the coastal areas keep those temperatures more moderate (average)

23. What causes hurricanes to form?

24. Hurricanes start as tropical storms near the tip of Africa. They travel across the Atlantic Ocean picking up LOTS of warm moist air – which causes EXTREMELY LOW PRESSURE on the surface.

25. EQUIPMENT USED FOR FORECASTING thermometer barometer Anemometer (wind speed) Psychrometer (humidity)

26. Describe the formation and results of Low pressure

27. Low pressure is formed as warm air rises, leaving less air molecules at the surface. As the warm air rises, it cools, condenses and forms clouds. Resulting weather is usually warmer and cloudy

28. Describe the formation and results of High pressure

29. Cool, dense air aloft sinks, pushing air molecules toward The surface. With the added pressure, clouds are unable to form, so clear skies prevail.
