Document Summary
Physical geography: holistic environmental science, environmental as resource and hazard. Atmosphere: it is in the ocean, it impacts our lives. What we need: e-text, practice exams, flash cards. Processes: atmospheric physics, energy and material states and flows, moisture conditions and dynamics. Patterns: result from processes, spatial manifestations of weather and climate, weather maps, satellite images, climate classification. Stomach cancer from water: 8,000-45,000 deaths/year. 21,000 deaths/year best estimate: settles and concentrates in low areas like basements with little circulation, fixed through ventilation. 3 mains things we looks for: air temp, barometric pressure, precipitation. Basic instrumentation: thermometers, rain gauges, barometer, anemometers and wind vanes, hygrographs, solar radiometer. Infrared thermometer: measures intensity of infrared radiation. Barometer: mercury barometer (1644, aneroid barometer (1843, units of measure. The minimum temp found from the wet bulb is the dew point. Dew point temp temp: the temp at which condensation would occur if you cool the air off that much. Mainly h2 and he: second atmosphere.
