The formation of clouds.
What is Condensation?
This front stays in place for an extended period causing long periods of precipitation.
What is a stationary front?
This heat transfer passes its heat from one form of matter to another form of matter by direct contact.
What is Conduction?
This North American air mass gets its characteristics from a source region over a cold piece of land.
What is Continental Polar?
A dark funnel of cloud extends below a storm and touches the ground.
What is a tornado?
The cause of global winds.
What is unequal heating of the Earth?
The process of liquid water changing into gas water (water vapor).
What is evaporation?
What this symbol represents on a weather map.This gas is the most abundant type of gas in our atmosphere.
What is a cold front?
This heat transfer passes its heat from one form of matter to another form of matter through empty space.
What is Radiation?
The two things that cause air masses move in the United States.
What are Prevailing Westerlies and Jet Stream?
The strongest of storms, a rapidly rotating storm system characterized by a low-pressure center.
What is a hurricane?
Occurs during the day when land warms faster than water causing a low pressure area over the land.
What is a sea breeze?
The process of water falling from the clouds to the ground.
What is precipitation?
When a warm air mass runs into a cold air mass and rises above it.
What is a warm front?
This heat transfer passes its heat through currents of fluids or air.
What is Convection?
This type of air mass is a low pressure system.
What is a warm air mass?
A storm with large amounts of snow, winds greater than 35 mph, and visibility of less than ΒΌ mile for at least three hours
What is a blizzard?
The reason winds moving from the equator to the north pole are deflected East (right).
The percent of water vapor in the air compared to the percent it could hold at a particular temperature.
What is relative humidity?
What is an occluded front?
The source of energy that heats the surface of the earth.
What is the Sun?
The boundary where air masses meet.
What is a front?
What is a hurricane?
The belts of global winds closest to the equator.
The two things that drive the water cycle.
What are gravity and energy from the sun?
A cold air mass pushes into and under a warm air mass. The warm air rises, cools and thunderstorms may occur.
What is a cold front?
The heat transfer that causes currents of air around the globe to move heat from the equator to the poles.
What is convection?
mP is its abbreviation.
What is maritime polar?
Caused when cold air masses move across warm bodies of water.
What is a Lake Effect Snow Storm?
Bands of high-speed winds 10 kilometers above the Earth.
What are the Jet Streams?
