Forming in flat layers, it covers all or most of the sky in a dull gray color.
What is a Stratus cloud?
100
This example of "Extreme Weather" is a small storm, often accompanied by heavy precipitation, frequent thunder, and lightning.
What is a Thunderstorm?
100
This is a type of scientist who studies the causes of weather, and tries to predict it.
What is a Meteorologist?
100
This is the process in which water molecules in liquid water absorb energy and escape into the air as water vapor.
What is Evaporation?
100
This front forms when temperature cools, and the warm air mass is cut off, or occluded from the ground.
What is an Occluded Front?
200
These are two clouds that are the most common "Middle Level" clouds.
What are Altostratus clouds and Altocumulus clouds?
200
This form of "Extreme Weather" occurs when so much water pours into a stream or river, that the river's banks overflow.
What is a Flood?
200
This occurs when a small change in recent weather, can trigger a big weather change in the soon future.
What is the "Butterfly Effect?"
200
This is the process in which molecules of water vapor in the air become liquid water.
What is Condensation?
200
This is the HIGH pressure center of dry air.
What is an Anticyclone?
300
This cloud forms at or near the ground, often produced when ground cools at night after a warm or humid day.
What is Fog?
300
This is a form of tornado, that occurs over a lake or an ocean.
What is a Water sprout?
300
These are the symbols that point to the direction where a cold front is moving.
What are triangles?
300
This is the amount of water vapor contained in the air.
What is Humidity?
300
This front is capable of causing abrupt weather changes,(Example: Thunderstorms).
What is a Cold Front?
400
These clouds are towering with flat tops. They are capable,(and often do) produce rain and thunderstorms.
What are the characteristics of a Cumulonimbus cloud?
400
In California, this type of "Extreme Weather" generally only occurs at high elevations.
What is a Snowstorm?
400
This is the first step in forecasting the weather.
What is collecting data? (Examples: Making observations and using instruments)
400
This is substance is liquid water that condenses from the air onto a cooler surface.
What is Dew?
400
In the United States, these are the winds that air masses are moved by.
What are Jet Streams, and Prevailing Westerlies?
500
These clouds often indicate that a storm is on it's way.
What is a Cirrocumulus cloud?
500
This dome of water sweeps across the coast, where hurricanes land. It is a result of low pressure, and high hurricane winds.
What is a Storm Surge?
500
On a weather map, this is the symbol for full cloud coverage.
What is a fully shaded in circle?
500
This is the temperature at which condensation begins.
What is the Dew Point?
500
This is a dry air mass that forms over land.
What is a Continental Tropical air mass?
