Components of the Climate System Discuss each component in terms of: Response time- how quickly it responds to inputs Heat capacity- amount of energy that must be put into the component to cause a change Albedo - reflectivity of incoming short wave radiation Atmosphere Geosphere - land Cryosphere -ice Hydrosphere -ocean Biosphere - Vegetation - Anthrosphere
Background image of page 8
Atmosphere Response time Strong diurnal cycle Fastest response to perturbation- days to months Mixes globally in months to years Heat Capacity Low heat capacity Easily heated and set into motion Strong vertical and horizontal gradients
