Unit 8 Vocabulary
| Term | Definitioner |
|---|---|
| Wind | The moving of air caused by differences in air pressure is called wind. |
| Global winds | These wind systems occur at or near earths surface and are called global winds. |
| Jet Stream | Jet streams are narrow belts of high-speed winds that blow from west to east, between 7 km and 16 km above earths surface. |
| Local Winds | Unlike global winds, local winds are the movement of air over short distances. |
| Ocean Currents | The oceans contain stream-like movements of water called ocean currents. |
| Surface Currents | Ocean currents that occur at or near the surface of the ocean, caused by wind, are called surface currents. |
| Coriolis Effect | The deflection of moving objects from a straight path due to earths rotation is called the Coriolis effect. |
| Deep Currents | Movement of ocean water far below the surface are called Deep Currents. |
| Convection Currents | In the ocean, a convection current is a movement of water that results from density differences. |
| Upwelling | The warm surface water is then replaced my cold, nutrient-rich water from the deep ocean in a process called Upwelling |
| Weather | Weather is the short term state of the atmosphere at a given time or place. |
| El Nino | El Nino is a periodic change characterized by above-average ocean temperatures across the Pacific Ocean, |
| La Nina | La Nina is a periodic change during which below-average ocean temperatures occur in the eastern Pacific Ocean |
| Weathering Forecast | Weathering forecasting is the analysis of scientific data to predict the future weather conditions. |
| Meteorology | The study of weather and earths atmosphere is called meteorology. |
| Station Model | A station model is a set of meteorological symbols that represent the weather at a particular observing station. |
| Barometer | Measures atmospheric pressure, used for forecasting the weather and determining altitude. |
| Hygrometer | Measures the humidity of the air or gas. |
| Pyschrometer | Thermometer readings being used to determine atmospheric humidity. |
| The Gulf Stream | A warm ocean current of the northern Atlantic ocean off the eastern North America. |
| Climate | The weather conditions prevailing in an area in general or over a long period. |
| Anemometer | Measures the speed of wind, or of any current gas. |
| Warm Front | The boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure |
| Cold Front | The boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system. |
| Stationary Front | A pair of air masses, neither of which is strong enough to replace the other. |
| Occluded Front | A composite front produced by occlusion. |
| mP | The representative of the voters to a parliament. |
| mT | A natural elevation of the earth's surface rising more or less abruptly to a summit, and attaining an altitude greater than that of a hill, usually greater than 2000 feet (610 meters) |
| cP | Cerebral palsy Cerebral palsy: An abnormality of motor function (the ability to move and control movements) that is acquired at an early age, usually less than 1 year, and is due to a brain lesion that is nonprogressive. Abbreviated CP. |
| cT | The CT scan can reveal anatomic details of internal organs that cannot be seen in conventional X-rays. |
| cA | Circa, means "approximately" in several European languages (and as a loanword in English), usually in reference to a date. |
