| relative humidity | ratio of water vapor contained in specific volume of air compared with how much water vapor that amount of air can hold |
| humidity | amount of water vapor in the air |
| temperature inversion | increase in temperature with height in an atmospheric level, inverts the temperature-altitude relationship |
| lifted condensation level | height at which condensation occurs |
| condensation | cooling gas changes into a liquid |
| dew point | air is cooled at a constant pressure to reach saturation |
| heat | transfer of energy that occurs because of a difference in temperature between substances |
| temperature | measurement of how quickly or how slowly molecules move around |
