| Fluid | Anything that flows and fills its container such as a liquid or a gas |

| High Pressure Area/ System | An area where the atmospheric pressure is greater than the rest of the atmosphere |
| Hurricane | Another name for a tropical cyclone that typically forms in the Atlantic ocean |
| Lightning | An electrostatic discharge or sudden and momentary flow of electric charge through the atmosphere between the clouds and the ground |
| Low Pressure Area/ System | An area where the atmospheric pressure is lowest compared to the surrounding area |
| Occluded Front | Formed when a cold front overtakes a warm front and in the process "cuts off" the warm front from contact with the ground |
| Stationary Front | A boundary between two different air masses, neither of which is strong enough to replace the other |
| Storm | Any disturbance in the atmosphere, especially affecting it's surface, and strongly implying serve weather marked by strong wind,thunder,lightning, and heavy precipitation |
| Storm Surge | An offshore rise of water caused primarily by high winds pushing on the ocean's surface which force the water to pile up higher than the ordinary sea level |
| Thunder | A sonic shock wave (sonic boom) created from the rapid expansion and explosion of the air molecules surrounding and within a bolt of lightning, due to increases in pressure and temperature |
| Thuderstorm | A weather phenomena that results from the rapid upward movement of warm, moist air inside air masses or at fronts and are characterized by the presence of cumulonimbus clouds, lightning, thunder, and different types of precipitation |
| Tornado | A violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or,in rare cases,the base of a cumulus cloud |
| Tropical Cyclone | A storm system that develops over large bodies of warm water at specific temperatures and is categorized by a large low-pressure center surrounded by numerous rotating thunderstorms that produce strong winds and heavy rain |
| Typhoon | The name given to a tropical cyclone that typically forms in the western pacific and Indian oceans |
| Warm Fronts | Defined as the leading edge of a warm air mass overtaking a cooler, slower air mass |
