Cards Term climate Definition long-term weather patterns Term aerosals Definition minute particles and liquid droplets Term convection currents Definition redistribute heat and moisture Term stratosphere Definition more dilute than troposphere, but contains almost no water and 1,000 times ozone (O3) Term thermosphere Definition ionized gases and high temperatures (ionosphere...) Term greenhouse effect Definition trapping of heat bu tje earth's atmosphere, which is transparent to incoming visible light rays but absorbs outgoing longwave infrared radiation Term latent heat Definition stored energy Term why does it rain? Definition water condenses as air cools and air cools as it rises Term coriolis effect Definition apparent curvature of the winds Term coriolis effect Definition apparent curvature of the winds Term jet streams Definition found at top of troposphere, hurricane force wind Term monsoons Definition regular, seasonal wind and rain Term Milankovitch cycles Definition explanation of climate shifts at different time scales: one explanation is periodic changes in sunlight intensity resulting from these cycles: 1) shape of earth's orbit around the sun elongates and shortens in a 100,000 year cycle, 2) the axis of rotation changes it's angle of tilt in a 40,000 year schedule, 3) over a 26,000 year time period, tje axis wobbles like an out-of balance spinning top Term el nino Definition major ocean current/climate connection that effects weather throughout the pacific Term Intergovernmental Panel on Climate Change Definition inter-nation approach to asses current knowledge of the state of climate change Term photochemical oxidants Definition compunds formed wiht solar energy Term fugitive emmisions Definition do not go through smoke stack Term converntional/criteria pollutants Definition sulfur dioxide, carbon monoxide, particulates,volatile organic compounds, nitrogen oxides, ozone, lead - most serious threat to humans Term unconventional pollutants Definition less volume but especially hazardous/toxic to humans Term sulfur dioxide Definition colorless, corrosive gas - major component of acid rain Term nitrogen oxides Definition highly reactive gases - initial products oxidizes (can be many different ways) Term carbon monoxide Definition less common than carbon dioxide but more dangerous - incomplete combustion of fuel Term Clean Air Act Definition acid rain, urban smog, toxic air pollutants, ozone protection, marketing pollution rights, VOC's, ambient ozone, soot, dust, NOx emissions
