Air masses
Maritime Polar(mP)
over ocean(moist air) polar(cold air)
Air mass
large bodies of air that have uniform temperature, humidity and pressure.
Cold fronts
cold air moves under warm air forcing warm air up
Air pressure
It is the force exerted on a surface by the air above it as gravity pulls it to Earth.
What is an air mass
An air mass are horizontal shapes of air that have similar characteristics.
Maritime Tropical(mT)
over ocean(moist air) tropical(warm air)
Latitude
Earth’s surface is divided into three temperature zones based on latitude.
Warm front
A warm front occurs where warm air mass displaces a cold air mass displaces a cold air mass.
What is a high pressure system.
large body of circulating air with high pressure at its center and lower pressure outside the system; brings sunshine and good weather
What factors impact what air is like in an air mass
An air mass is a large body of air with generally uniform temperature and humidity.
Continental Polar(cP)-
over land(dry air) polar-(cold air)
Altitude
the height of an object or point in relation to sea level or ground level.
Stationary front
A stationary front is a nonmoving boundary.
Low-pressure system
large body of circulating air with low pressure at its center and higher pressure outside the system; brings clouds and precipitation
Continental Tropical(cT)
over land(dry air) tropical(warm air)
occluded front
An occluded front occurs when a cold front catches up to a warm front or a warm front catches up to aa cold front.
Humidity
a quantity representing the amount of water vapor in the atmosphere or in a gas
weather front
are used to show the movement of air masses.
