Key concepts: weather, meteorology, climate, climatology, air mass, source region, continental polar (cp, maritime polar (mp, gulf/atlantic maritime tropical (mt, pacific (mt, air mass modification, humified. Weather-short term (hours: day to day condition of the atmosphere, forecast-future conditions for a particular day, more chaotic, less predictable than climate, national weather service (nws) Synoptic conditions: the evaluation of weather data collected at a specific time, same view , numerical analysis, databases of wind, pressure, temperature, and moisture. Weather forecasting: figure 8. 17, asos-automated surface observing system, awips-advanced weather interactive processing system. Doppler radar: radar, radio detection and ranging, sends a microwave signal and listens for the reflection, how the original signal was altered, changes frequency give velocity, the doppler effect. Doppler effect: change of frequency caused by motion of the source, passing train or police car. Air masses: the earth"s surface gives the overlying air its characteristics, temperature and moisture, stability, based temperature and moisture of the source region.
