Weather & Climate<br />What is the difference between weather and climate? Or are they the same?<br />Climate is what we expect. <br />Weather is what we get.<br />
Coriolis Effect<br />What is the Coriolis effect? <br />The apparent curve of the winds on earth.<br />
Prevailing Winds<br /><ul><li>Air moving from a high pressure area to low pressure area = wind.
Westerlies:prevailing winds that go from west to east over the United States</li></li></ul><li>
Iceland Volcano Plume<br />What could happen if there are more large eruptions in the near future?<br />The Year Without a Summer 1816: Caused by the 1815 Eruption of Mount Tambora in Indonesia. <br />93 cubic miles of ash into the stratosphere.<br />Many parts of the world had snow in summer, heavy rainfall, crop failures, disease and starvation due to lack of sunlight.<br />
Check your understanding…<br />So why is it important to know the direction winds blow at different latitudes?<br />Sailing (exploration, trading, pirates in the Caribbean)<br />Predict weather conditions<br />
Earth’s surface features affect weather and climate<br /><ul><li>Variations in Earth’s topography affect the climate of a region
Oceans/Great Lakes</li></li></ul><li>Mountains<br />Review <br />Mountains=Rain Shadow Effect<br /><ul><li>Prevailing windscarry moist air up windward side of mountains
Air rises over mountain, cools and condenses (forms clouds). Air loses capacity to hold moisture = precipitation (rain/snow)</li></li></ul><li>Rain shadow…..<br /><ul><li>Leewardsideof mountain-- cool, dry air warms as it descends.
Deserts can form on leeward side of mountain.</li></li></ul><li>
Mixing of winds create severe thunderstorms and........</li></li></ul><li>Tornadoes!<br />Aurora, CO June 2009<br />
Aurora’s Weather and Climate<br />Use the information you have learned today and your experience with the weather in Aurora to answer the question:<br />“What factors influence the weather and climate we have in Aurora?”<br />Use at least 4 of these words/phrases in your explanation:<br />Rain shadow, plains, leeward, Westerlies, proximity to the ocean, windward, altitude.<br />
Latitude and Climate Zones<br />Latitude: The distance of a place north or south of the equator <br />(remember: latitude=ladder)<br />Equator: 0o = warmest weather all year<br />Temperatures get cooler the further north and south you go<br />
Climate Zone Maps<br />How to correctly color your maps:<br />Leave lakes and oceans UNCOLORED<br />Take time to look at the map when coloring. Can you predict the climate of a region by its terrain, distance from equator or poles, or proximity to water?<br />Use a different color for each climate zone if you can.<br />1. Begin the reading. <br />When you read POLAR ZONES: ICE CAPS, pick your first color and color the word ICE CAPS. Select a new color for TUNDRA and do the same. Read the POLAR ZONES paragraph and then color in the polar zones on the map. (ICE CAP=A and TUNDRA=B)<br />Repeat the same process for each climate zone. <br />
