Document Summary
Relative humidity y amount of moisture present in atmosphere in relation to amount the atmosphere can hold given the present temperature y deserts have very low relative humidity while tropical regions have very high. Ocean conveyer belt (thermohaline gradient) y deep water circulation of oceans from surface to sea floor y. Important in transport of heat from equator to higher latitudes and therefore influences global atmospheric circulation y driven by density gradients in salt and temperature. Greenhouse gases y gases in the troposphere intercept and absorb infrared radiation as it travels to outer space from the surface of the planet. Include water vapor, co2, methane, nitrous oxide and ozone y. Enhanced greenhouse effect y additional warming that results from increased levels of co2 and other gases that absorb infrared radiation y co2 is the gas of most concern in causing enhanced warming.
