Tropical Humid

• 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 Wet Dry

• 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.

5
ARID(DESERT)

• 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.

6
Semiarid

• 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.

7
Mediterranean

• 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.

8
Marine West Coast

• 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

9
Humid Subtropical

• 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

10
Humid Continental

• This climate region experiences
  a variety in temperature and
  precipitation.
• Mostly found in mid-latitude (40s 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.

11
SUBARCTIC

• Evergreen forests called TAIGA
• 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.
• Boreal Forest
• http//www.blueplanetbiomes.org/taiga.htm

12
TUNDRA

• 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.
• http//www.blueplanetbiomes.org/tundra.htm

13
Ice Cap

• 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)
• Found only on the continent of Antarctica

14
HIGHLANDS(Alpine)

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