| Term | Definition |
|---|---|
| Anemometer | an instrument used to measure wind speed |
| Conduction | the direct transfer of thermal energy from one substance to another substance that it is touching |
| Convection | the transfer of thermal energy by the movement of fluid |
| Convection current | the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another |
| Coriolis effect | the effect of Earth’s rotation on the direction of winds and currents |
| Electro-magnetic wave | waves that can transfer electric and magnetic energy through the vacuum of space |
| Global wind | winds that blow steadily from specific directions over long distances |
| Greenhouse effect | the process by which heat is trapped in the atmosphere by water vapor, carbon dioxide, methane, and other gases that form a “blanket” around Earth; the trapping of heat by a planet’s atmosphere |
| Heat | the transfer of thermal energy from one object to another because of a difference in temperature |
| Infrared radiation | electromagnetic waves with wavelength that are longer than visible light but shorter than microwaves |
| Jetstream | bands of high-speed winds about 10 km above Earth’s surface |
| Land breeze | the flow of air from land to a body of water |
| Local winds | winds that blow over short distances |
| Radiation | the direct transfer of energy through space by electromagnetic waves |
| Scattering | reflection of light in all directions |
| Sea breeze | the flow of cooler air from over an ocean or lake toward land |
| Thermal energy | the total energy of motion in the particles of a substance |
| Ultraviolet radiation | electromagnetic waves with wavelengths that are shorter than visible light but longer than x-rays |
| Wind | the horizontal movement of air from an area of high pressure to an area of lower pressure |
| Wind-chill factor | a measure of cooling combining temperature and wind speed |
