| barometer | measures pressure |
| thermometer | measures temperature |
| wind vane | measures wind direction |
| anemometer | measures wind speed |
| nephoscope | measures direction of cloud movement |
| rain gauge | measures amount of rain fall |
| hygrometer/psychrometer | measure amount of moisture in the air |
| high pressure | air particles are close together |
| low pressure | air particles are farther apart |
| air pressure | caused by weight of atmosphere above us |
| dew point | temperature at which moisture will begin to condense out of the air |
| relative humidity | amount of water vapor in the air |
| Which holds more moisture--warm air or cold air? | warm air |
| What is relative humidity for saturated air? | 100% |
| saturated air | air is holding max amount of moisture |
| evaporation | water changes from liquid to gas by absorbing heat |
| condensation | water changes from gas to liquid by releasing heat |
| wind | air in motion |
| wet-bulb/dry-bulb | used to determine dew point and relative humidity using tables |
| precipitation | moisture falling from clouds in the form of rain, snow, sleet, or hail |
| two units for temperature | Celcius and Fahrenheit |
| cumulus clouds | fluffy, puffy |
| stratus clouds | layered sheets |
| cirrus clouds | wispy (like hair) |
| nimbus clouds | hold rain |
| alto- | prefix for mid-level clouds |
| cirro- | prefix for high-level clouds |
| fog | cloud that forms at ground level |
