Chapter 9-Global Climates and Climate Change Flashcards
What is the difference between weather and climate?
Weather is what you feel, climate is the expected average
What are the factors that influence climate?
latitude, season, air mass circulation
Why is climate classification useful?
Helps understand different climate regions
What are the 3 A-type climates?
Tropical Wet (Af), Tropical Savanna (Aw), Tropical monsoon (Am)
What are the B-type climates like? Where are they located?
Arid and in subtropics (marine desert)
What are C-type climates like? Where are they located?
Mild midlatitude and in most of the world (hot summers, mild winters)
What are D-type climates like?
4 distinct seasons, higher latitude, microthermal
What are E-type climates like?
Most extreme, tundra (ET), icecaps (EF)
What is proxy data?
indirect evidence of an event or past conditions
Example of human proxy data?
Harvest records, ship logs, letters, diaries
Example of natural proxy data?
Pollen in lakes, tree ring patterns, ice core analysis
What is Milankovitch theory?
A way to categorize time periods geologically
What is eccentricity in Milankovitch theory?
100,000 year cycle and due to interaction with gravitational fields of Jupiter and Saturn
What is tilt obliquity in Milankovitch theory?
40,000 year cycle
What is orbital precession in Milankovitch theory?
23,000 year cycle and changes axis direction
