THERMAL ENERGY TRANSFER IN THE ATMOSPHERE
ATMOSPHERIC PRESSURE |
|
Definition
* The pressure exerted by the mass of air above any point on Earth's surface
* It is the force exerted on a surface by the air above it as gravity pulls it to Earth. Atmospheric pressure is commonly measured with a barometer

CONDUCTION |
|
Definition
* The transfer of thermal energy by direct contact between the particles of a substance, without moving the particles to a new location
* This is a flow of heat by direct contact. Heat travels from a warmer object toward a colder object |

CONVECTION |
|
Definition
* The transfer of thermal energy through the movement of particles from one location to another
* Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature. Warm air is less dense than cold air, and so convection currents can form in the presence of a temperature gradient |

CORIOLIS EFFECT |
|
Definition
* The deflection of any object from a straight line path by Earth's rotation
* The Coriolis effect is defined as how a moving object seems to veer toward the right in the Northern hemisphere and left in the Southern hemisphere. An example of the Coriolis effect is hurricane winds turning left in the Northern hemisphere |

CURRENT |
|
Definition
* Flow from one place to another in one direction
*Current is defined as the movement of water in a specific direction |

DENSITY |
|
Definition
* Mass per volume of a substance
* Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density |

FLUID |
|
Definition
* Any substance that has no definite shape & tens to flow
* Gasses, plasma & liquids are fluids
*A fluid is any substance that flows or deforms under applied shear stress |

JET STREAM |
|
Definition
* A band of fast moving air in the stratosphere
* Jet streams are fast flowing, relatively narrow air currents found in the atmosphere around 10 kilometers above the surface of the Earth |

RADIATION |
|
Definition
* The emission of energy as radiant energy
* Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium |

WIND |
|
Definition
* The movement of cool air from an area of high atmospheric pressure to an area of low atmospheric pressure
*Wind is moving air and is caused by differences in air pressure within our atmosphere. Air under high pressure moves toward areas of low pressure. The greater the difference in pressure, the faster the air flows |
