Aerosols: small solid or liquid particles suspended in the atmosphere (creates smog, reduces visibility) History of meteorology: (see slide 8 of pp01) Weather: atmospheric conditions at a particular time and place: temp, pressure, humidity, cloud cover, precip, visibility, wind speed & direction. Climate: the average weather over a long (10yr) period of time: includes weather records, climate changes over long periods of time, is changing now, cannot use individual weather events to prove or disprove changes in climate! Radar: views precipitation from the ground: doppler radar: can sense motion of precipitation particles toward/away from radar. Winds generally from west, move weather from west to east. 8/29/16 pressure and vertical structure of the atmosphere.
