Presentation Transcript

  1. Climate Lesson What factors contribute to a region’s climate?

  2. Weather vs Climate? • Weather: Atmospheric conditions (temperature, rainfall, etc…) at a specific point in time • Climate: Atmospheric conditions (temperature, rainfall, etc…) of a region over a long period of time

  3. Houston, Texas • Weather - Climate

  4. Notes Template • Use this template to create your own notes from the Power point. Zones of Latitude Factors that affect climate

  5. Zones of Latitude • A region’s latitude (distance from the equator) can impact its climate. • Sketch the diagram below. Polar Temperate Tropical Tropical Temperate Polar

  6. High Latitude = ______________ zone, _____ ° N _____ ° S, where is it? • Middle Latitude = _______________ zone, _____ ° N _____ ° S, where is it? • Low Latitude = _________________ zone, _____ ° N _____ ° S, where is it?

  7. Zones of Latitude • Tropical Zones:Warm weather year round. Area between the Tropic of Cancer (23 ½ º N) and the Tropic of Capricorn (23 ½ º S). • Temperate Zones:Warm summers and cold winters (four seasons). Areas between Tropic of Cancer (23 ½ º N) and Arctic Circle (66 ½ º N) and Tropic of Capricorn (23 ½ º S) and the Antarctic Circle (66 ½ º S). • Polar Zones: Cold year round. Areas north of the Arctic Circle and south of the Antarctic Circle.

  9. 1. Which cities will have a temperate climate? 3. Which cities are in the polar zone? 2. Which cities are warm year-round? What is this zone of latitude called?

  10. Notes Template • Use this template to create your own notes from the Power point. Rain Shadows Zones of Latitude Topography Factors that affect climate

  11. Topography - Elevation • Elevation is the height above sea level • The higher the elevation of a region the cooler the temperature becomes. Cooler Temperatures Warmer Temperatures

  12. Topography – Rain Shadows • Mountains can create uneven rainfall. • The windward side of the mountain is rainy while the leeward side is very dry. • Rain Shadows are desert regions created on the leeward side of the mountain Which side is the leeward side, the right or the left? Windward Which side is the windward side, the right or the left?

  13. Asia Precipitation Map • Which gets more more rain point A or point B. • What causes the difference in rainfall amounts between point A and point B? B A Hint: Rain comes from here

  14. Asia Precipitation Map • Which gets more more rain point A or point B. • What causes the difference in rainfall amounts between point A and point B? B A Hint: Rain comes from here

  15. If you said Point A gets more rain because the Himalayas act as a rain shadow you are correct. Desert – arid region with very little rainfall Humid Subtropical – warm temperatures, lots of rainfall

  16. Notes Template • Use this template to create your own notes from the Power point. Elevation Rain Shadows Zones of Latitude Topography Cities Factors that affect climate

  17. Cities • Buildings, parking lots, streets and other city structures made of metal or asphalt absorb a lot of heat. • This heat is transferred to the air. • Increased smog and air pollution further trap this heat – creating the: heat island effect.

  18. Notes Template • Use this template to create your own notes from the Power point. Elevation Rain Shadows Zones of Latitude Topography Cities Factors that affect climate Warm Currents Ocean Currents Cold Currents

  19. Ocean Currents • Ocean current move in large circular systems • Ocean currents affect temperature and precipitation of an area. • Warm ocean currents make surrounding areas warmer and rainy. • Cool ocean currents make surrounding areas cooler and drier Warmer and Rainy Warm Ocean Current Cooler and Drier Cool Ocean Current

  20. Ocean Currents

  21. Map Questions • Use the map on p. 153 of your textbook to answer the questions below. • What is the climate of Madagascar? What is the climate of Japan? • Which types of climate are present in the tropical zone of latitude? • http://www.mcwdn.org/MAPS&GLOBES/Climate.html

  22. Notes Template • Use this template to create your own notes from the Power point. Elevation Rain Shadows Zones of Latitude Topography Cities Factors that affect climate Warm Currents Climate Changes El Niño Ocean Currents Global Warming Cold Currents

  23. Global Warming • Global Warming is the build up of carbon dioxide (greenhouse gases) in the atmosphere trapping heat and causing increase temperature and shifting weather patterns. • Global Warming is being caused by both the human release of greenhouse gases from the burning of fossil fuels (oil, coal) and a natural warming cycle the Earth is going through • As the global temperature begins to rise many changes will occur to climates around the world • Complete the global warming simulation on the class webpage. • What are the effects of global warming?

  24. El Niño • The natural warming of waters off the west coast of South America about every 2 – 7 years due to a reversal of wind direction. • El Nino causes floods and mudslides in the Americas. • El Nino causes droughts in Australia and Asia.

  25. Climographs • Climographs are a combination of a line graph, measuring average temperature, and a bar graph, measuring average rainfall, for each month. Temperature Rainfall

  27. Major Climate Regions • Tropical Wet: Always hot and rain falls almost daily (Amazon Rainforest) • Desert: Receives less than 10 inches of rain per year (Phoenix, AZ) • Semiarid: Receives between 10 and 16 inches of rain per year (West Texas) • Mediterranean: Dry and hot summers, cool and rainy winters (Los Angeles, CA) • Humid Subtropical: Hot and humid summers, mild to cool winters (Houston, Tx) • Marine West Coast: Located close to warm ocean currents. Moderate temperatures and constant rainfall (Seattle, WA). • Humid Continental: Hot summers and Cold winters. Located in the interior, far away from oceans. Have four distinct seasons (St. Louis, MO). • Tundra: Always cold. Flat, treeless lands around the Arctic Ocean. Very little rain. Land has permafrost. (Greenland)
