Weather 11.1

2. A region near Earth's surface where the air pressure is greater than that of the surrounding area.
3. The state of the lower atmosphere in a specific place and at a specific time, including temperature, precipitation, wind, humidity, air pressure, and cloudiness.
5. The pressure at any location in the atmosphere, caused by the weight of the column of air above the location. Units for it include millimeters of mercury (mm Hg), atmospheres (atm), and millibars (mb).
8. An instrument used to measure air pressure.
9. A technology that uses reflected radio waves to detect objects.
15. Winds that form because of a large-scale convection current and blow in a belt that circles the planet. They are also called prevailing winds.
17. A front where a warm air mass replaces a colder air mass.
18. A tool for measuring temperature.
20. A front where a cold front overtakes a warm front.
21. Unable to absorb any more of a solute.

1. A fast-moving current of air that blows west to east around Earth, high above Earth's surface.
4. A ratio that describes the amount of water vapor in the air. It is reported as a percentage of the total amount of water vapor air can hold at a certain temperature.
6. A measure of how hot or cold something is. It is also a measure of the average kinetic energy of the particles in a substance.
7. The study of the atmosphere, including weather.
10. A large body of air that has a consistent temperature and humidity.
11. A boundary between two air masses.
12. A front between warm and cold air masses where neither air mass is moving forward.
13. The amount of water vapor in the air.
14. A front where a cold air mass replaces a warmer air mass.
16. A region near Earth's surface where the air pressure is lower than that of the surrounding area.
19. Rain, snow, hail, or any other form of water that forms via the condensation of water vapor in the atmosphere and then falls to Earth.
