| The smallest atmospheric scale of motion | microscale |
| Refreshing breeze from the ocean to land during a summer afternoon along the ocean shore | sea breeze |
| Phenomenon associated with warmer than normal ocean temperatures in the eastern tropical Pacific Ocean | El Nino |
| Rising of deeper cold ocean water to the surface | upwelling |
| Warm ocean current off the east coast of the United States | Gulf stream |
| The cold northerly ocean current off northern California | California Current |
| Line of constant pressure | isobar |
| Type of jet stream typically found around 30 degrees latitude | subtropical jet stream |

| Transition zone between two distinct air masses with different densities | front |
| Type of weather front labeled by a red line with red semicircles | warm front |
| Type of weather front labeled by a blue line with blue triangles | cold front |
| Fourth type of weather front, besides cold front, warm front, and occluded front | stationary front |
| Type of weather front in which a faster moving cold front overtakes a warm front | occluded front |
| Theory that explains the life cycle of a most extratropical cyclones | polar front theory |
| Spreading out of air, commonly found in the upper troposphere above a surface cyclone | divergence |
| First stage of the life cycle of a mid-latitude cyclone | stationary front |
| Last stage of the life cycle of a mid-latitude cyclone | cut-off |
| Life cycle stage for a mid-latitude cyclone that follows the frontal wave stage | open wave stage |

| Large atmospheric cell between 30 and 60 degrees latitude | Ferrel Cell |
| Large stable cold anticyclone over Asia in winter | Siberian high |
| The type of atmospheric circulation due to heating and cooling of air in which warm, less dense air rises and cold, denser air sinks | thermal circulation |
| Snowfall downwind of the Great Lakes triggered by cold air passing over relatively warm, moist lakes | lake-effect snow |
| Narrow channel of high-level atmospheric moisture flowing from the tropics and subtropics to the mid-latitudes | atmospheric river |
