| Isobar | A line on a weather map that joins places that have the same air pressure. |
| Isotherm | A line on a weather map that joins places that have the same temperature. |
| Cyclone | A swirling center of low air pressure. Also known as a hurricane in the Atlantic ocean The “eye” has extremely low pressure |
| Anti-cyclone | A high-pressure center of dry air. The opposite of a cyclone: this is really nice weather! |
| Prevailing westerlies | Major wind belts over the continental United States which push air masses from west to east. |
| Electromagnetic waves | Waves that can transfer electric and magnetic energy through the vacuum of space. |
| Ultraviolet Radiation | Electromagnetic waves with wavelengths that are shorter than visible light but longer than X-rays. |
| Infrared Radiation | Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves |
| Scattering | Reflection of light in all directions. (as in a cloud or snow) |
| Doppler Radar | Use of radio waves which bounce off particles in the air such as raindrops or snow flakes. Different colors indicate the size and amount of rain drops |
| Satellite | Any object that orbits around another object in space. (the moon is an example) Weather satellites allow forecasters to observe the atmosphere and land from above and over much greater distances. |
