Weather
| Term | Definition |
|---|---|
| Map | A flat, 2-dimensional drawing of land and water. |
| Globe | A spherical scale model of the Earth. |
| Latitude | Geographic coordinate that specifies the north or south of the Equator. |
| Longitude | Distance measured in degrees east or west from an imaginary line (called the prime meridian) that goes from the North Pole to the South Pole and that passes through Greenwich, England. |
| Hemisphere | A circle drawn around the Earth that divides it into two equal halves. |
| Weather | The state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, and precipitation. |
| Climate | The average weather conditions in an area over a long period. |
| Atmosphere | The envelope of gasses surrounding the earth. |
| Cirrus | White wispy clouds that form at high altitudes and are always made of ice crystals. |
| Cumulus | Fair weather clouds with white puffy tops and dark flat bottoms. |
| Stratus | Lowest clouds that cover the sky like a thick gray blanket. |
| Nimbus | Precipitating cloud, such as Nimbostratus or Cumulonimbus cloud. |
| Cumulonimbus | A huge vertical cloud that can produce a thunderstorm. |
| Land Breeze | A breeze blowing toward the sea from the land, especially at night, because the sea is warmer than the land. |
| Sea Breeze | A breeze blowing toward the land from the sea , especially during the day, because land is cooler than the sea. |
| Precipitation | Water that falls to the Earth’s surface as rain, snow, sleet, or hail. |
| Evaporation | The process of changing from a liquid to a gas. |
| Condensation | The process of changing from a gas to a liquid. |
| Jet Stream | a steady worldwide wind that blows from west to east high above Earth |
| Gulf Stream | A warm current that starts near the equator and moves from Florida all the way to Iceland. |
| Air Mass | A large “bubble” of air that has about the same temperature and humidity throughout it. |
| La Niña | During La Niña winters, the South sees warmer and drier conditions than usual. The North and Canada tend to be wetter and colder |
| El Niño | A warming of the ocean surface, or above-average sea surface temperatures, in the central and eastern tropical Pacific Ocean. |
| Temperature | The average speed of the particles in a substance. |
| Air Pressure | The weight of the air pushing on everything around it. |
| Humidity | Water vapor in the air. |
| Thermometer | A tool that measures temperature. |
| Barometer | A weather instrument that measures air pressure. |
| Anemometer | An instrument for measuring the speed of the wind, or of any current of gas. |
| Wind Vane | Is an instrument that measures the direction from which the wind is blowing. |
| Rain Gauge | A device for collecting and measuring the amount of rain which falls. |
| Front | Is a boundary between two air masses of different densities |
| Hurricane | A storm with a violent wind, in particular a tropical cyclone in the Caribbean. |
| Rain | Moisture condensed from the atmosphere that falls visibly in separate drops. |
| Freezing Rain | Rain that freezes on impact with the ground or solid objects. |
| Sleet | A form of precipitation consisting of ice pellets, often mixed with rain or snow. |
| Snow | Atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer. |
| Hail | Pellets of frozen rain which fall in showers from Cumulonimbus clouds. |
| Clouds | A visible mass of condensed water vapor floating in the atmosphere, typically high above the ground. |
| Wind | The perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction. |
| Trade Winds | The wind that flows towards the equator from the North-East in the Northern Hemisphere or from the South-East in the Southern Hemisphere. |
| Prevailing Westerlies | Prevailing winds from the West toward the East in the middle latitudes between 30 and 60 degrees latitude. |
| Polar Westerlies | Prevailing winds from the West toward the East in the middle latitudes between 30 and 60 degrees latitude. |
| Low Pressure | A condition of the atmosphere in which the pressure is below average |
| High pressure | A condition of the atmosphere in which the pressure is above average |
| Coriolis Effect | The result of Earth's rotation on weather patterns and ocean currents |
| 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. |
| Warm Front | The boundary of an advancing mass of warm air, in particular the leading edge of the warm sector of a low-pressure system. |
| Occluded Front | Forms when a warm air mass gets caught between two cold air masses. |
| Stationary Front | A front between warm and cold air masses that is moving very slowly or not at all. |
