Weather and Climate – Air Masses Fronts and Water in the Air

Flashcard maker : Lily Taylor

Condition of earths atmosphere at a particular time and place
Water Cycle
The continuous process by which water moves from Earths surface to the atmosphere and back
The amount of water vapor in the air

Relative Humidity
The comparison of the actual amount of water vapor to the amount of water vapor that would be in the air if it saturated.
The change from a gas to a liquid
Dew Point
The temperature at which condensation begins
Any form of water that falls from clouds and reaches Earths surface. Rain, Snow, Sleet, Freezing Rain, Hail, Dew,
Air Mass
A huge body of air that has similar temperature, humidity, and air pressure throughout
Maritime Polar Air Mass
wet and cold air mass
Maritime Tropical Air Mass
warm and wet air mass
Continental Polar Air Mass
cold and dry air mass
Continental Tropical Air Mass
warm, dry air mass
Arctic Air Mass
forms over arctic regions, very cold
The leading edge of a weather system
Cold Front
A front where cold air moves in under a warm air mass.
forms when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow
Warm Front
A front where warm air moves over cold air and brings drizzly rain and then are followed by warm and clear weather
Stationary Front
A boundary between warm and cold air masses that dont move, causing rain for several days.
Occluded Front
a front where a warm air mass is caught between two colder air masses and brings cool temperatures and large amounts of rain and snow
The change of a liquid to a gas
the process by which water evaporates from a plants leaves
The movement of water through soil.
The movement of water through the openings in rock/soil
Run Off
Water that flows over the ground surface rather than soaking into the ground.
Latin for heap;
Fluffy, white clouds, usually with flat bottoms, that look like rounded piles of cotton.
Latin for stretched out;
Clouds that form in flat layers and often cover much of the sky.

Latin for curl;
Clouds that look thin, wispy, or feathery.
water falling in drops from vapor condensed in the atmosphere
precipitation falling from clouds in the form of ice crystals
Formed when rain falls through a layer of freezing air.
Ice pellets larger than 5 millimeters in diameter formed in cumulonimbus clouds by strong updrafts of wind
A large mass of tiny, condensed water drops ie: cirrus, cumulus and stratus
