Air Masses
A large body of air is called what?
an air mass
This front is represented by red circles
warm front
This is the type of weather that is caused by a cold front.
thunderstorms, heavy rains, heavy snow, severe storms, etc.
This is a stream like movement of ocean water in a regular pattern.
ocean current
This is the type of weather associated with a high pressure system.
clear skies (happy weather)
This air mass forms over warm water.
maritime tropical (mT)
This front forms when a cold air mass slides under a warm air mass and lifts it up to form clouds (also associated with bringing severe weather)
cold front
This is the type of weather caused by a warm front.
gentle rain or snow
These 2 factors can make water more dense.
more salt and colder temperature
The uneven heating of the Earth causes this phenomenon.
wind
This air mass forms over land that is cold, such as Russia.
All fronts bring this.
Precipitation (rain, sleet, hail, or snow)
This is the amount of moisture in the air.
humidity
One thing that effects surface currents.
winds, continental deflection, or coriolis effect
During the day land heats more quickly than the water causing the air to rise and allowing the air from the water to come in taking its place. This process is called a what?
sea breeze
This air mass can bring hot, humid weather in the summer.
maritime tropical
This front is when a cold air mass meets a warm air mass and neither one move
stationary front
One of the 2 types of winds that are mostly responsible for moving air masses around
Prevailing Winds and The Jet Steam
The process of water vapor in the air cooling in order to form clouds is called this.
This is the tool that a meteorologist would use to measure air pressure
barometer
This air mass can bring heavy snow in the winter
maritime polar (mP)
This front forms when a cold air mass meets a cool air mass with a warm air mass in the middle. The warm air mass gets cut off from the ground and is forced upward to create clouds.
occluded front
This ocean current effects weather on the east coast of the US as well as Europe.
The Gulf Stream
This is the process of plants releasing water vapor into the air.
transpiration
This pressure system cause winds to blow in a counterclockwise direction, rising, and creating clouds that can bring forth severe weather.
Low Pressure
