Chapter 1 - Hazardous Earth - Global Atmospheric Circulation Flashcards
1
Q
What do winds transfer?
A
Heat from the equator to the poles
2
Q
How can heat also be transferred?
A
Ocean Currents
3
Q
What are the main three convection currents?
A
Hadley, Polar, Ferrel
4
Q
Pressure belts caused by atmospheric circulation cause variation in climate: What are these?
A
Dry, Tropical, Polar
5
Q
How is arid (dry) climate caused?
A
Slinking air from the Hadley and Ferrel cells meeting, causing high pressure - prevents rainfall.
6
Q
How is tropical climate caused?
A
Rising air from the two Hadley cells meeting, causing low pressure - lots of rainfall.
7
Q
How is polar climate caused?
A
Slinking air from the Polar cells - high pressure. Temperature and rainfall are low (all year).
