Weather Review

TermDefinition
hurricane A severe storm that develops over tropical oceans and whose winds of 120 km/h or faster spiral in toward that
cold front the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.
station model A pattern of metorological symbols that represents the weather at a particular observing station and that is recorded on a weather map
midlatitude cyclone the boundary of an advancing mass of cold air, in particular the trailing edge of the warm sector of a low-pressure system.
barometer an instrument that measures atmospheric pressure
air mass a large body of air throughout which the temperature and moisture content are similar
thunderstorm usually a heavy, brief storm that consists of rain, strong winds, lighting and thunder.
wind vane determines direction of wind
radar a system that uses reflected radio waves to determine the velocity and location of objects
stationary front a front of air masses that moves either very slowly or not at all
Continental polar, Maritime polar, continental tropical, and maritime tropical are all examples of what? air masses
Meteorologists use symbols and colors to make weather maps
continental air masses that affect the weather of North America come from Canada and Mexico
A destructive, rotating column of air that has very high wind speeds and that may be visible as. a funnel shaped cloud is what? tornado
Anemometer an instrument for measuring the speed of the wind, or of any current of gas.
meteorologists have Not tried to control- tornadoes
The front edge of an advancing warm air mass that replaces colder air with warmer air is warm front
Condensation Nuclei A suspended particle that provides a surface for condensation
the temp at which condensation equals evaporation dew point
any form of moisture that falls to earths surface from clouds precipitation
collection of water droplets or ice crystals suspended in the air cloud
energy that is absorbed or released during a phase change latent heat
the mass of water vapor contained in a given volume of air humidity
the process which a solid changes directly into a gas sublimation
a mass of water vapor that condenses near the surface of earth fog
the ratio of actual water vapor content in the air to the amount of water vapor needed to reach saturation relative humidity
what is a low-altitude, billowy cloud called? cumulus cloud
water vapor changes into a liquid in the process of condensation
precipitation formed in cumulonimbus clouds when convection currents repeatedly carry raindrops to high levels is hail
the process which the temperature of an air mass decreases as the air rises and expands is called adiabatic cooling
fog that results from the nightly cooling of earth is called radiation fog
the purpose of cloud seeding is to induce precipitation
advective cooling occurs when a warmer body of air from another source passes across a colder surface.
occulated front forms when a cold front meets a warm front when a cold front overtakes a warm front. When this occurs, the warm air is separated (occluded) from the cyclone center at the Earth's surface.
maritime polar air masses are cool, moist, and unstable.
anticyclone calm, fine, clear weather
continental polar cold temperatures and little moisture
continental tropical dry air mass formed over land in area close to the equator. Mexico
maritime tropical warm temperatures and rich in moisture.
large cloud formations associated with storm systems form by- lifting
what forms when the dew point falls below the freezing temperature of water and water vapor turns directly to ice frost

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
