Weather Quiz Study Flashcards

A set of vocabulary flashcards covering air masses, pressure systems, weather fronts, gas laws, and classroom demonstrations based on the lecture transcript.

Polar Air Mass

A cold air mass.

Tropical Air Mass

A warm air mass.

Maritime Air Mass

A humid air mass.

Continental Air Mass

A dry air mass.

Cold Front

A front where the temperature drops fast, pressure rises, precipitation is steadily-heavy rain, and the duration is short.

Warm Front

A front where the temperature rises slowly, pressure rises slightly then falls, precipitation is long and steady rain, and the duration is long.

Occluded Front

A front where temperature increases (warm or cold-warm) or decreases (cold), pressure drops or increases, and precipitation is steady and light for a long duration.

Stationary Front

A front where temperature is not very affected, characterized by low pressure, and precipitation can be humid and long or dry and none for a long duration.

High Pressure System

Characterized by clear sunny weather and cold air that cools and falls; wind moves in a $(w$ direction.

Low Pressure System

Characterized by stormy and rainy weather and warm air that warms up and rises; wind moves in a $ccw$ direction.

Boyle's Law

A gas law where tempuratus is constant; an example is a pump into a bottle.

Charles' Law

A gas law where pressure is constant; an example is boiling water in an open container.

Gay-Lussac's Law

A gas law where volume is constant; an example is a pressure cooker.

Unit Demonstrations

Includes split tank, thermometer with pump and vacuum, marshmallows, balloon over flask, can crush, test tube, "hand boiler", bag of chips, cloud in a bottle, and fire piston.
