Fronts
A transition zone between two different air masses at the Earth's surface.
What is a front?
Made of water drops or ice crystals floating in the sky.
What are clouds?
These are devices used to monitor the weather.
What are weather instruments?
The movement of air caused by the uneven heating of the Earth by the sun and the Earth's own rotation.
What is wind?
Water that collected in the air and becomes too heavy for the air to hold. It falls back to the Earth as rain, sleet, or snow.
What is precipitation?
Lighter and slower moving moist air that moves in over continental polar mass.
What is a warm front?
These are high, wispy "hair-like" clouds with fuzzy edges.
What are cirrus?
This instrument is used to measure temperature.
What is a thermometer?
These are winds that blow east to west just north and south of the equator. They often help ships travel west.
What are trade winds?
The process where the sun heats up water and turns into vapor.
What is evaporation?
Dry, dense fast moving air that wedges under a continental tropical air mass.
What is a cold front?
These are low-level straight clouds.
What are stratus clouds?
This instrument is used to measure air pressure.
What is a barometer?
Winds that blow from a single direction over a specific area of the Earth.
What are prevailing winds?
The process where water vapor in the air cools down, it changes back into a liquid. In the sky, this makes clouds. Sometimes, it occurs on the outside of a glass.
What is condensation?
Two air masses that are not strong enough to displace the other and results in days of rain.
What is a stationary front?
These are puffy and look like fluffy white cotton balls. They are associated it with nice weather.
What are cumulous clouds?
This instrument is used to measure wind speed.
What is an anemometer?
Winds that occur in belts that go all around the planet.
What are global winds?
Symbol that is all read with half circles.
What is a warm front?
These are mid-level layers or patches of clouds.
What are alto clouds?
A scale used to measure the speed of the wind. It goes from 0-12.
What is the Beaufort Scale?
Moves from west to east and is like a moving sidewalk for airplanes.
What are jet streams?
Forms when a warm air mass gets caught between two cold air masses.
What is an occluded front?
These are rainy, end of world types of clouds.
What are nimbus clouds?
This instrument is used to measure relative humidity.
What is a sling psychrometer?
Makes things (like planes or currents of air) traveling long distances around Earth appear to move at a curve as opposed to a straight line. Affects weather patterns, it affects ocean currents, and it even affects air travel. It's responsible for many large scale weather patterns.
What is the Coriolis Effect?
