Weather and Climate

This comprehensive overview delves into the Earth's atmosphere, exploring the composition of air, including nitrogen and oxygen, and the role of microorganisms in gas production. It discusses atmospheric layers like the troposphere and stratosphere, the dynamics of wind caused by air pressure differences, and humidity's influence on weather patterns. Key climate determiners such as temperature, precipitation, latitude, and ocean currents are examined, along with phenomena like El Niño and climate change. Insights into energy conservation strategies and U.S. climate policy are also included.

Presentation Transcript

  1. Weather and Climate Glenco Chapter 17 Pearson Chapter 24

  2. Earth’s Atmosphere • The air is a mixture of gases, Nitrogen, Oxygen and trace gases. • Microorganisms produce the gases. • The theory is that over time the atmosphere developed into the air we now breath.

  4. Atmospheric structure • Weather takes place in the Troposphere. • Ozone is in the Stratosphere. As altitude increases, Air pressure and density Decrease.

  5. Latitudes and Longitudes

  6. Latitude and Longitude • These affect the climate based on the angle of the Sun’s rays.

  7. Heating (energy in) the Atmosphere

  8. Wind • Winds are caused by differences in air pressure • Local Winds: are caused by unequal heating of the earth’s surface in a small area.

  9. Global Winds • Winds that blow over long distances from a specific direction. • Move in huge bands called convection cells • Warm air at the equator rises and replaced by cooler air. • Called, Trade winds,Westerlies, and polar easterlies

  11. Water in the Atmosphere

  12. Humidity • The amount of water vapor in the air • This can condenses as dew, frost or fog if the air temperature drops.

  14. Classifying clouds

  15. Using your book add details to the types of clouds. Pg 762-763

  16. Weather Patterns • Pg 765- 771 in Pearson book • Answer 24.5 assessment questions 1-6 pg 771

  17. Climates • Two things determine a regions climate: • Temperature and Precipitation

  18. Temperature • Latitude • Distance from large bodies of water • Ocean currents • altitude

  19. Precipitation • Latitude • Distribution of air pressure systems • Global winds • Mountain barriers http://mycozynook.com/102RGCh34OH.htm

  20. El Nino • Warming of water in central and eastern Pacific Ocean • A current of water moves west • Causes a different weather pattern

  21. Global Warming now called Climate Change • One possible theory is the increase of Co2 and other gases in the atmosphere is causing climate change. • The green house effect.

  22. Possible cures • Energy Conservation • Alternative non carbon producing power sources: Please list them for yourselves. • Reduce the amount of gases produced.

  23. Research • Using your laptops please research and write a one paragraph summation of current US policy addressing Climate Change. • Google: “current US policy on climate change” • EPA.gov/ climate change
