Chpt. 20 Patterns & Severe Storms
| Question | Answer |
|---|---|
| a scientist who studies the Earth's atmosphere, especially in relation to weather and climate | meteorologist |
| the ratio of the amount of water vapor in the air compared to the amount needed to reach saturation at a specific temperature | relative humidity |
| the abnormal rise of the sea along a shore as a result of strong winds | storm surge |
| a large body of air with similar temperatures and amounts of moisture at any given altitude | air mass |
| the behavior of the atmosphere - wind, temperature, pressure and precipitation - at a particular place and time | weather |
| any form of water that falls from a cloud to Earth's surface (rain, snow, sleet, hail) | precipitation |
| the condition when air contains the maximum amount of water vapor it can hold at a given temperature | saturated |
| the boundary between two adjacent air masses that have different or contrasting characteristics | front |
| the amount of water vapor in the air | humidity |
| the temperature to which air must be cooled to reach saturation | dew point |
| an instrument used to measure relative humidity | sling psychrometer |
| a line connecting points of equal atmospheric pressure on a weather map | isobar |
| a stratus cloud that forms at or near the ground when air is cooled to its dew point and condenses | fog |
| a pattern of meteorological symbols describing the weather at a particular location | station model |
| a front formed when a cold front overtakes a warm front and forces the warm air mass upward, producing heavy rain followed by light rain | occluded front |
| a front along which a warm air mass overrides a retreating mass of cooler air | warm front |
| a front along which a cold air mass thrusts beneath a warmer air mass | cold front |
| a situation in which the surface position of a front does not move | stationary front |
| a storm produced by a cumulonimbus cloud and accompanied by lightning and thunder, usually accompanied by strong wind gusts, heavy rain and sometimes hail | thunderstorm |
| a small, very intense cyclonic storm with exceedingly high winds, most often produced along cold fronts in conjunction with severe thunderstorms | tornado |
| a tropical cyclonic storm having winds in excess of 119 km per hour (recall cyclonic = L Pressure) | hurricane |
| the doughnut-shaped area of intense cumulonimbus development and very strong winds that surrounds the eye of a hurricane | eye wall |
| a zone of scattered clouds and calm averaging about 20 km in diameter at the center of a hurricane | eye |
