| a scale of wind intensity | Beaufort Scale |
| an instrument that measures atmospheric pressure | barometer |
| a 1-5 rating based on a hurricane’s present intensity | Saffir-Simpson Hurrican Scale |
| a device that emits radio waves for detecting and locating an object by the reflection of the radio waves and that may use this reflection to determine the object’s direction and speed | Radar |
| an instrument used to measure wind speed | Anemometer |
| assigns a single number (1-10) to quantify the size of an earthquake | Richter Scale |
| a small circle that shows the location of the weather station; a specified pattern for entering, on a weather map, the meteorological symbols that represent the state of the weather at a particular observation station | Station model |
| an instrument that measures and indicates temperature | Thermometer |
| used to rate the intensity of a tornado by examining the damage caused by a tornado after it has passed over a man-made structure; rating from F0-F5 | Fujita Scale |
| warm air moves over cold, denser air bringing drizzly rain followed by clear and warm weather | Warm Front |
| one who reports and forecasts the weather | Meteorologist |
| the area in which two types of air masses meet; the boundary between air masses of different densities and usually between different temperatures | Front |
| station for tracking, recording and reporting observations of the weather | Weather Station |
| a warm air mass is caught between and above two cold air masses, has cool temperatures and large amounts of rain or snow | Occluded Front |
| the height of an object above a reference level, usually above sea level or the Earth's surface | Altitude |
| cold air moves under warm air bringing thunderstorms, heavy rain or snow | Cold Front |
| a movable device attached to something high to show which way the wind is blowing | Weather Vane |
| a cold and warm air mass meet but neither is strong enough to move the warm air mass over the cold, usually brings many days of cloudy wet weather | Stationary Front |
