Global Temperatures Flashcards
1
Q
What kind of system is Earth?
A
Open system
2
Q
Average energy output for Earth?
A
240 W/m^2
3
Q
Insolation in Tropics
A
- high angle
- constant year round
- little seasonal variation
- energy SURPLUS
4
Q
Insolation in Polar Regions
A
- low angle insolation (1/2 the year)
- light surfaces
- energy DEFICIT
5
Q
Where is there an energy balance, latitude wise?
A
40 degress
6
Q
Sensible Heat Flux-> symbol and definition
A
- H
- transfer of heat between surface and air
- conduction and convection
7
Q
Heat flux is LOW when…
A
Temperature surface > temperature of air
8
Q
Heat flux is ZERO when…
A
surface temp = air temp
9
Q
Heat Flux is HIGH when
A
Temperature surface < temperature of air
10
Q
Ground Heat Flux -> symbol definition
A
- energy which flows out/into the ground
- through conduction
11
Q
Ground Flux is LOW when…
A
Temperature surface > temperature deep soil
12
Q
Ground Flux is ZERO when…
A
temperature surface = temperature deep soil
13
Q
Ground Flux is HIGH when
A
temperature surface < temperature deep soil
14
Q
Urban Heat Islands
A
- regular 1-6 degrees Celsius > surrounding
- similar desert surface energy characteristics
- max and min temps > surroundings
15
Q
Temperature Controls: Latitude
A
- insolation
- different latitudes, different insolation angle
- polar (deficit of energy, cooler), tropics (surplus, hotter)
