weather and climate Flashcards
the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc. (short term conditions)
Weather
the weather conditions prevailing in an area in general or over time (long term averages)
Climate
the transfer of kinetic energy from one medium or object to another, or from an energy source to a medium or object. Such energy transfer can occur in three ways: radiation, conduction, and convection.
Heat
a measure of how hot or cold something is
Temperature
energy that is transmitted in the form of electromagnetic radiation
Radiant energy
a huge body of air that has similar temperature, humidity, and air pressure at any given height
Air mass
(meteorology) the atmospheric phenomenon created at the boundary (dividing line) between two different air masses
Front
narrow belt of strong winds that blows near the top of the troposphere
Jet Stream
a gauge for recording the speed and direction of wind
Anemometer
measures relative humidity
Hygrometer
An instrument used to measure changes in air pressure
Barometer
the amount of water vapor in the air
Humidity
the percentage of water vapor in the air compared to the maximum amount the air could hold
Relative humidity
the temperature at which condensation begins
Dew Point
a number that reflects a combination of high temperatures and high humidity
Heat Index
