1. Troposphere—the lowest level of the atmosphere which extends outward from the earth’s surface, and in which generally temperature decreases rapidly with altitude, clouds form, and convection is active.
2. Air pressure—pressure exerted on the earth by gravity pulling the air toward earth’s surface.
3. Wind—convecting current in air.
4. Local winds—blow from any direction and cover a short distance.
5. Global winds—blow from a specific direction and usually travel long distances.
6. Radiant energy—visible and invisible energy from the sun that moves in waves. The process by which heat is transferred through a substance.
7. Conduction—from one substance to another by direct contact of one molecule with another.
8. Convection—transfer of heat energy in a fluid (gas or liquid). 9. Radiation—the transfer of heat energy through space.
10. Barometer—an instrument for measuring air pressure.
11. Air mass—large body of air that has the same temperature and humidity throughout.
12. Humidity—the amount of water vapor in the air.
13. Condensation—the changing of gas into a liquid.
14. Cumulus cloud—a puffy white cotton ball-like cloud with a flat base.
15. Cold front—a boundary formed when a cold air mass slides under a warm air mass and pushes the warm air along.
16. Warm front—the boundary formed when a warm air mass slides over a cold air mass and pushes the cold air along.
17. Climate—average weather in a given area over a long period of time.
18. Meteorology—the science that deals with the study of the atmosphere and the weather.
19. Microclimate—the smallest climate zone.
20. Altitude— height above sea level.
21. Latitude—distance north or south of the equator in degrees.
22. Weather—a condition of the atmosphere.
23. Anemometer—instrument used to measure wind speed.
24. Rain gauge—instrument used to measure rainfall.
25. Thermometer—instrument used to measure temperature.
26. Folklore—stories handed down from generations past.
27. Forecast—foresight of consequences and provision against them.
