Term | Definition |
---|---|
Fluid | Is anything that flows and fills its container such as a liquid or gas. |
Front | The boundary separating 2 or more different types of air masses. |
High Pressure Area/ System | An area where the atmospheric pressure is greater than the rest of the atmosphere. |
Hurricane | Is another name for a tropical cyclone that typically forms in the Atlantic Ocean. |
Lightning | Is an electrostatic discharge or the sudden and momentary flow of electric charge through the atmosphere between the clouds and the ground. |
Low Pressure Area/ System | Is an area where the atmospheric pressure is lowest compared to the surrounding area. Storms like tropical cyclones are called low-pressure cells. |
Occluded Front | Is 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 | Is a boundary between two different air masses, neither of which is strong enough to replace the other. |
Storm | Is any disturbance in the atmosphere, especially affecting its surface, and strongly implying severe weather marked by strong wind, thunder, lightning, and heavy precipitation. |
Storm Surge | Is an offshore rise of the 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 | Is a sonic shock wave (sonic boom) created from the the rapid expansion & explosion of the air molecules surrounding and within a bolt of lightning, due to increases in pressure and temperature. |
Thunderstorm | Is 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 | Is 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 | Is a storm system that develops over large bodies of warm water at specific temperatures and is characterized by a large low-pressure center surrounded by numerous rotating thunderstorms that produce strong winds and heavy rain. |
Typhoon | Is the name given to a tropical cyclone that typically forms in the western Pacific & Indian Oceans. |
Warm Front | Is defined as the leading edge of a warm air mass overtaking a cooler, slower air mass. |
Runoff | Liquid precipitation that is not absorbed into the ground. Water that flows across the surface of the Earth |
Water Cycle | The repeating processes that move water in different forms between Earth's surface and the atmosphere. |
Water Vapor | Water in the atmosphere that is in the form of a gas. |
Weather | The condition of Earth's atmosphere at a particular time and place. |
Air Mass | Is a huge body of air that forms over a region characterizing it with a similar temperature, humidity and pressure at any given height. |
Cold Front | Is defined as the leading edge of a cooler air mass, replacing or overtaking a warmer air mass. |
Precipitation | Any type of liquid or solid water that falls to Earth's surface. |
Sublimation | The process of water changing from a solid directly into a gas. |
