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