This powerpoint is purposefully made for AS Level Geography using the Cambridge syllabus.

It fully covers - 2.1 Energy budgets

2.1.1 Energy budget systems
• Inputs and outputs: incoming (shortwave) solar radiation, outgoing (longwave) terrestrial radiation,
absorption, reflection (albedo), scattering, conduction, back radiation.
• Transfers: latent heat transfer and sensible heat transfer.

2.1.2 The global energy budget
• Latitudinal pattern of radiation: excesses and deficits.
• Natural greenhouse effect.

2.1.3 Global transfers of energy
• Atmospheric transfers: tri-cellular model of atmospheric transfer (Polar, Ferrel and Hadley cells,
intertropical convergence zone (ITCZ)), wind belts, jet streams.
• Oceanic transfers: vertical and horizontal transfers by ocean currents and ocean gyres.
• Relationships between atmospheric transfers and oceanic transfers.

2.1.4 Seasonal variations in temperature, pressure and wind belts
• Influence of latitude, land/sea distribution, ocean currents.

2.1.5 Diurnal energy budgets
• Differences between daytime and nighttime.
