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.
