Air Masses/Fronts
What type of pressure system does a large Red "L" represent?
low pressure system
Name this step of the water cycle: when water changes from liquid to a gas
ex: puddle formed in the morning is gone by afternoon
evaporation
this type of air mass forms over the ocean, has warm temperatures, and has brings wet air with lots of moisture
Maritime Tropical
This front is formed when warm air slides up and over cold air. Clouds form with gentle rain or flurries.
Warm front
This tool measures air temperature.
What type of pressure system does a Big Blue "H" represent?
High pressure system
Name this step of the water cycle: water falls back to the ground
ex: rain, snow, sleet, hail
precipitation
This type of air mass forms over the ocean, has cold temperatures, and brings wet air with lots of moisture
Maritime Polar
This front is formed when cold air pushes under war air, causing warm air to rise. Thunderstorms, high winds and more severe weather occurs.
Cold front
The tool that measures the amount of precipitation.
What is a rain guage?
What weather conditions does a low pressure system bring?
cloudy, precipitation
Name this step of the water cycle: water vapor cooling and returning to a liquid
ex: beads of water collecting on glass of ice water on a hot day
condensation
What type of air mass forms over land, brings cold temperatures, and dry air
Continental Polar
This front is formed when warm air and cold air meet and neither forces other one to move. Clouds form and it may rain or snow for several days.
Stationary
The two things that affect the density of water.
What is temperature and salinity (salt concentration)?
What weather conditions does a high pressure system bring?
sunny, clear skies
a large body of air with similar temperature, humidity, and air pressure
air mass
What type of front is represented by blue triangles?
cold front
What would you expect to happen when a new air mass enters an area?
a change in weather will occur
Name this step of the water cycle: water runs down Earth's surface and collects in oceans and other water sources.
ex: water trickling down a hill back into a lake
run-off/collection
This type of air mass forms over land, has warm weather and has dry air
Continental Tropical
What type of front is represented by red semicircles?
Warm front
This tool measures air pressure
What is a barometer?
the area where 2 air masses meet but do not mix
front
The two driving forces of the water cycle?
What are heat from the Sun and gravity?
The two things that define an air mass.
What are temperature and humidity?
This type of front is fromed when cold air overtakes a warm front and produce thunderstorms.
What is an occluded front?
This tool measures air speed.
What is an anemometer?
Name this step of the water cycle: plants releasing water vapor from leaves
ex: water droplets collecting on walls/roof of a greenhouse
transpiration
The name of the DEEP ocean current.
What is the Global Ocean Conveyor Belt?
