Weather.

5. :Global air circulation patterns within the atmosphere held to Earth by gravity and warmed as heat radiates from earth; influenced by convection of warm, less dense air and cool,dense air
6. :the boundary between a warm air mass and a receding cooler air mass
8. :A body of air extending over a large area that develops and retains certain characteristic of pressure, temp, and humidity
11. :a map or chart that shows the weather conditions at a specific point over a specific region
12. :the border between an advancing cold air mass and a retreating warm air mass
13. :air temperature
16. :an air mass with greater atmospheric pressure than the surrounding air masses; air moves away from the center of the high pressure, travelling in a clock-wise direction in a northern hemisphere and a counterclockwise direction in the southern hemisphere

1. :measures relative humidity
2. :an insturment that measures the amount of atmospheric pressure
3. :amount of water vapor or moisture content in air
4. :an air mass with less atmospheric pressure than the surrounding air mass, air moves toward the area of low pressure, traveling in a counterclockwise direction in the northern hemisphere and a clockwise direction in the southern hemisphere
6. :measures wind direction
7. :measures air pressure
9. :the force exerted by the atmosphere on Earth's surface by the weight of the air above the surface
10. :measures wind speed
14. :the day-to-day state of the atmosphere
15. :The day-to-day state of the atmosphere.
