Atmosphere
Layers of air surrounding Earth.
Atmosphere
Process in which matter changes from a gaseous state to a liquid state; also, matter that has condensed on a cold surface, such as water on the outside of a cold glass.
Condensation
The general weather of an area over a long period of time, and includes seasonal changes in weather.
Climate
Conditions in the atmosphere, including humidity, cloud cover, temperature, wind, and precipitation.
Weather
Cool, moist air mass that forms over an ocean near a polar area.
Maritime Polar
Form of oxygen that has three atoms in one molecule.
Ozone
Water falling from clouds in any form, such as snow, ice, raindrops, or drizzle.
Precipitation
The distance of a place north or south of the equator, affects the temperatures that commonly occur in an area.
Latitude
The use of reflected radio waves to determine the distance of an object and the direction it is moving.
Radar
Hot, dry air mass that forms over Mexico and moves north.
Continental Tropical
Cycle in which water moves through the environment, through the process of evaporation, condensation, and precipitation.
Water Cycle
A wind that blows steadily in the same direction across thousands of kilometers.
Global Winds
The distance of a place above sea level, affects an area's temperature.
Elevation
A shorthand way of recording weather at a particular weather situation.
Station Model
Cold, dry air mass that forms over Canada and moves south.
Continental Polar
The continuous movement of water between the surface of Earth and the troposphere.
Hydrologic Cycle
Effect that Earth’s rotation has on the path of air and water moving at or above its surface, causing the fluid’s path to curve.
Coriolis Effect
The shape of the land, can affect the amount of precipitation an area receives.
Topography
Large body of air that has about the same temperature and humidity throughout it.
Group of tiny liquid water droplets hanging in the air.
Clouds
Change of matter from a liquid state to a gaseous state.
Evaporation
Narrow stream of high-speed wind high in the atmosphere, generally moving west to east in the Northern Hemisphere.
Jet Stream
Global Winds
Warm, humid air mass that forms over an ocean near tropical and subtropical areas.
Maritime Tropical
A measure of the weight of the atmosphere per unit of area on Earth’s surface; also called barometric pressure.
