Heating Of The Atmosphere - Chapter 2 Flashcards
Conduction (Definition)
Transfer of heat through contact
Convection (Definition)
Heat transfer via vertical air movement
Radiation (definition)
Heat transfer by the absorption of long wave radiation
Release of latent heat (definition)
Heat transfer when condensation takes place
Advection (definition)
Heat transfer via horizontal air movement
Turbulence (definition)
Heat transfer by turbulent air movements
Advection (Example)
Such as air travelling from a warm air source off of the continent
Insulation (Definition)
The amount of energy per unit area
Insulation (Example)
The sun rays at the polar regions are more spread therefore heat up a larger area so the overall temperature is lower (greater area).
Regions on the equator receive more concentrated amounts of sun energy and so have an overall greater temperature rise as there is less area.
Heat transfer in water:
- Difficult to heat
- More Evaporation (than land masses)
- Convection currents occur within the water body
Transfer of heat in ice & snow:
- More energy is used to try and change the state of the ice/snow rather than increase it’s temperature.
- A lot of the energy is reflected.
Transfer of heat in vegetation:
- Used for their growth
- Moisture is evaporated
Transfer of heat in cities:
-Absorbed by buildings and roads and then re-radiated
Therefore built-up areas are usually warm
Temperature Inversion:
As altitude increases, so does the temperature (Not the expectation)
Isothermal Temperature:
As altitude increases, temperature remains constant for part of the increase in altitude (not a usual expectation).
