Chp 8 Flashcards
What was the early classification system of the Greeks?
Torrid
Temperate
Frigid
Koppen system-How do we use Climographs?
-Uses colors and shades to classify the world into five climate zones based on criteria like temp.
-To compare climates in different places.
Upon what two criteria did Koppen base his system?
Temp and precipitation
T/F
The B climate are the less extensive in area and the only ones classed primarily in precipitation
F
It is the most extensive one
Wayne Ne is found in which one of these climate types?
Dfa
What group is Tropical Humid Climates?
Group A
What group is Dry climates?
group B
What group is mild Midlatitude climates?
Group C
What group is severe Midlatitude climates?
Group D
What group is Polar and Highland climates?
Group E ad H
Subtypes of Tropical climates and description
1) Tropical Wet Climate (Af) – Tropical rainy
2. Tropical Savanna Climate (Aw) – North or south of Tropical Wet Climates
3. Tropical Monsoon Climate (Am) – Wet and dry seasons
Subtypes and descrip of Group B
- Subtropical Desert Climate (BWh) - West coast, foggy deserts
- Subtropical Steppe Climate (BSh) – Occurs around edge of true deserts, slightly more ppt.
- Midlatitude Desert Climate (BWk) – Deserts of the continental interior
- Midlatitude Steppe Climate (BSk) – Grasslands of the continental interior
Subtypes and descrp of group C
8.Mediterranean Climate (Csa, Csb) – Dry summer subtropical
9. Humid Subtropical Climate (Cfa, Cwa, Cwb) – Southeast U.S. and Southeast China
10. Marine West Coast Climate (Cfb, Cfc) - U.S. Pacific Northwest & much of northwest Europe
Subtypes and descrip of group D
- Humid Continental Climate (Dfa, Dfb. Dwb) -Northern hemisphere only
- Subarctiic climate (Dfc, Dfd, Dwc, Dwd)- Northern hemisphere; annual temp range.
Subtypes and descrip group E and H
- Tundra Climate (ET) – Arctic fringes of northern hemisphere continents
- Ice Cap Climate (EF) – Antarctica-southern hemisphere & Greenland-northern hemisphere
- Highland Climate (Group H) – Climates on mountain slopes change too quickly over short
distances (even above higher elevations at the Equator) to be worth mapping.
Time Scales – How can we study climates of the past?
We infer past climates from evidence gathered both directly and indirectly:
Dendrochronology (tree rings), pollen analysis, fossil coral reefs, ice cores ocean sediments, etc.
What are the causes of long-term climate change?
Atmospheric aerosols
Fluctuations in solar output
Variations in Earth–Sun relations
Concentration of greenhouse gases
Feedback mechanisms
The roles of the ocean
Anthropogenic Climate Change – What is the evidence for current climate change?
Changes in air temperature, ocean temps/sea level/acidity, melting in polar regions, weather patterns
How do we use models to predict future climates?
Technology, computers and program that scientist uses
Addressing Climate Change:
Kyoto Protocol of 1987 started countries down the path of reducing greenhouse gas emissions.
