  1. World History/ GeoNovember 4th 2015 Warm Up: What is the difference between weather and climate?

  2. Weather Vs Climate • Weather is defined as the state of the atmosphere at some place and time, usually expressed in terms of temperature, air pressure, humidity, wind speed and direction, precipitation, and cloudiness. • Meteorologists study weather. • Climate is defined in terms of the average (mean) of weather elements (such as temperature and precipitation) over a specified period of time (30 years according to the World Meteorological Organization).

  3. The Köppen Climate Classification System • In the early 20th century, a German scientist named WladimirKöppen developed one of the most widely used classification systems. The Köppen system categorizes climate into five main types, which can be further divided into subcategories.

  4. Little variation in temperature over the year. It is always hot with a daily average temperature of 80 degrees Fahrenheit. Rains on a daily basis and yearly average rainfall is usually more than 80 inches. Found in Central and South America, as well as Africa ,South Asia (India), Southeast Asia and Indonesia . Associated with Rainforests and Jungles. Found along the Equator or areas close to the Equator. Tropical Climate

  5. This sub region has a rainy season in the summer and a dry season in winter. Temperatures are cooler in the dry season. Yearly rainfall is less than a Tropical Humid Climate. Tropical Wet & Dry climates are found next to tropical humid climates in Africa, South & Central America, and parts of Asia. The Savannah of Africa is a prime example. Tropical Wet & Dry

  6. Who would benefit from living in a tropical climate?

  7. Deserts are categorized by the amount annual rainfall received. Deserts receive less than 10 inches of rainfall per year. Hot deserts (Sahara) have low humidity and high temperatures during the day. At night the temperature falls because the dry air cannot hold heat well. ARID(DESERT)

  8. Who would benefit from living in a arid climate?

  9. This sub-region does not receive much precipitation at all – Usually about 16 inches per year. Summers are hot and winters are mild to cold. This climate is located in the interior of continents, or in a zone around deserts. Much of the American west falls into this climate type. Semiarid

  10. Who would benefit from living in a semiarid climate?

  11. Primarily found surrounding the Mediterranean Sea. Summers are dry and hot while winters are cool and rainy. Supports a dense human population and rich agricultural activity. Many of the first great human civilizations thrived in this climate. Mediterranean

  12. Who would benefit from living in a Mediterranean climate?

  13. Long periods of heat and humidity characterize this climate region. These areas are found on the east coast of continents and are often subject to hurricanes in late summer and autumn. Winters are mild to cool, depending on latitude. Very suitable for raising crops, (rice). Philadelphia, PA & South Jersey Humid Subtropical

  14. Who would benefit from living in a Humid Subtrpoical climate?

  15. Located close to the oceans and is frequently cloudy, foggy, and damp. Warm ocean waters off the coast moderates and keeps temperatures relatively constant throughout the year. Precipitation is evenly distributed throughout the year. Rains a lot throughout the year. Seattle, WA (Pacific Northwest) London, England Marine West Coast

  16. Who would benefit from living in a Marine west coast climate?

  17. This climate region experiences a variety in temperature and precipitation. Mostly found in mid-latitude (40’s to 50 degrees) interiors of northern hemisphere continents. These regions also experience four distinct seasons. NEPA is located in this climate region. Deciduous Forests thrive in this climate. HumidContinental

  18. Who would benefit from living in a humid continental climate?

  19. Evergreen forests cover the lands in this climate region. Huge temperature variations occur between summer and winter. Summers are short and cool while the winters are long & extremely cold. Temperatures at freezing or below last five to eight months of the year. SUBARCTIC

  20. Who would benefit from living in a subarctic climate?

  21. Tundra is the flat, treeless lands forming a ring around the Arctic Ocean. Almost exclusively located in the northern hemisphere Very little rainfall – less than 15 inches/year. Permanently frozen subsoil called “Permafrost” Summer only lasts a few weeks with temperatures around 40 degrees Fahrenheit. TUNDRA

  22. Who would benefit from living in a tundra climate?

  23. Snow, ice, and permanently freezing temperatures characterize this region. So cold it rarely snows. This region is sometimes referred to as a Polar Desert because it receives less than 10 inches of precipitation per year. Coldest temperature = -128.6o F (Vostok, Antarctica) Ice Cap

  24. Highland climates vary depending upon four factors: 1. Latitude 2. Elevation (Altitude) 3. Topography 4. Continental Location HIGHLANDS(Alpine)

  25. Who would benefit from living in these climates?
