Document Summary
Earth"s system"s controls on climate external forcing"s : changing radiation coming in, fluctuation in solar energy (radiation, orbital parameters, changing radiation going out, weathering and carbon cycle, ocean circulation, atmospheric circulation, atmospheric absorption and reflect, the greenhouse effect. Subtropical deserts: found at 20 to 30 n and s latitude, surface winds moving towards poles-deflected to come out of west to make westerlies, rising relatively moist at 60 n and s, low temperature, temperature rain forests. Planetary albedo=atmospheric reflection: reflectivity of sunlight, an albedo of . 3 indicate that 30% of the incident radiation is reflected, albedo of 0=perfect black body, albedo of 1=would apply to a perfectly white diffuse reflector. Albedo of earth"s surface: albedo and glaciation, more ice cover means more albedo (positive feedback to increasing glacial cover, melting causes lower surface albedo. This increases the amount of radiation absorbed by.
