What is weather?
A boundary between two air masses of different density, moisture, or temperature
What is a front?
A person who studies the weather
What is a meteorologist?
When cold air advances towards warm air
What is a cold front?
Masses of puffy, white clouds, often with flat bases
What are cumulus clouds?
Water falling from clouds
What is precipitation?
A large body of air that has properties similar to the part of Earth's surface over which it developed
What is an air mass?
A line that connects points of equal temperature on a weather map
What is an isotherm?
When lighter, warm air advances over heavier, cold air
What is a warm front?
High, thin, white, feathery clouds made of ice crystals
What are cirrus clouds?
This stratus cloud forms when air is cooled to its dew point near the ground.
What is fog?
A winter storm with 56/km/h winds, low temperature, visibility less than 400 m with falling or blowing snow
What is a blizzard?
A line drawn to connect points of equal atmospheric pressure on a weather map
What is an isobar?
When a boundary between two air masses stops advancing
What is a stationary front
These clouds form layers, or smooth, even sheets in the sky, usually at low altitudes.
What are stratus clouds?
The temperature at which air is saturated and condensation forms.
What is dew point?
A large, swirling low-pressure system that forms over the warm Atlantic Ocean
What is a hurricane?
This map, using a combination of symbols, shows the weather conditions at a specific location on Earth's surface.
What is a station model?
This forms when three air masses of different temperatures meet
What is an occluded front?
Clouds associated with rain or snow often have this word attached to them
What is nimbus?
The amount of water vapor present in the air?
What is humidity?
A violently rotating column of air in contact with the ground
What is a tornado?
This organization employs meteorologists to gather data and predict weather.
What is the National Weather Service?
This type of weather usually occurs at a rapidly advancing cold front.
What are thunderstorms
This prefix describes clouds that form at high altitudes
What is cirro-?
A measure of the amount of water vapor in the air compared to the amount needed for saturation at a specific temperature.
What is relative humidity?
Thunderstorms are formed by this type of cloud
What is cumulonimbus?
What is the dew point in this station model?
What is 28?
This kind of weather usually occurs at a warm front
