Air Mass
Body of air with same temp and moisture throughout
Air Pressure
Weight of air
Anemometer
Measure speed of wind
Atmosphere
Gases that surround Earth
Barometer
Detect and measure changes in air pressure
Barometric Pressure (Atmospheric Pressure)
Pressure exerted by atmosphere
Biofuel
fuel made from living materials
Biome
Area that contains specific plants and animals based on climate
Biosphere
Portion of Earth occupied by living things
Carbon Dioxide
Potent greenhouse gas that can be produced by burning fossil fuels
Chlorofluorocarbons (CFCs)
Chemical compounds that are harmful to the ozone layer
Climate
Weather conditions that are characteristic of a region or of a place over a long period of time
Climate Model
Predictive representation of a climate; mathematical equation
Climatologist
Scientist that studies science
Climatology
Study of climate
Cloud
Billions of tiny droplets of water or ice and dust particles visible from the ground
Cold Front
Leading edge of a cold air mass; occurs when a cold air mass pushes a warm air mass ahead of it
Condensation
Water vapor changing from a gas to liquid
Conduction
Heat transferring from one material to another material
Convection
Heat transferring through the movement of a gas or liquid
Convection Current (Convection Cell)
Circulating flow of air or water resulting from temp differences
Coriolis Effect
Force from rotation of Earth and affects the path of object in motion
Current
Movement of gas or liquid in a definite direction
Cyclone
Massive, rotating storm that forms in the Indian Ocean and off coast of Australia
Deposition
Water vapor changing from gas to solid
Dew Point (Point of Saturation)
Atmospheric temp at which water droplets condense, forming dew
Dixie Alley
Southeastern part of U.S. prone to violent tornadoes
Doppler Radar
Use Doppler effect to determine position and velocity of weather such as clouds or storms
Easterlies
Global Winds that flow from the east to the west
El Nino
An unusually warm flow of surface water that occurs in the equatorial Pacific Ocean about every 2-7 years
Enhanced Fujita Scale
Measures strength of tornados
Equinox (Spring-Vernal; Fall-Autumnal)
Time of year in which day and night are equal lengths
Evaporation
Water changes from a liquid to an invisible gas called water vapor
Exosphere
Outer region of the atmosphere
Geosphere
Solid position of Earth
Geothermal Energy
Energy from the heat of the Earth
Global Ocean Conveyor Belt (Thermohaline Circulation)
Slow moving, density-driven circulation of ocean water that runs nearly pole to pole and throughout the world’s oceans. The current runs in a loop, both along the ocean surface and thousands of meters below it
