Weather Fronts and Storms

Air Mass

Large bodies of air that have a similar temperature, density, and humidity. Can form over water or land and in tropical or polar regions

mT

Maritime Tropical

Rain, snow, sleet, or hail (any form of water falling from clouds)

precipitation

Rapidly whirling, funnel-shaped cloud that reaches down to Earth's surface

tornado

On a weather map, blue lines with triangles represent

cold fronts

What is the most violent part of a hurricane storm itself?

The eye wall

Stationary Front Map Symbol

A blue and red line with blue triangles and red half circles facing in opposite directions

A funnel cloud becomes a tornado when:

it touches ground

Hot, Dry Air Mass

Continental Tropical

A Cold Front forms…

When a cold air mass collides and pushes a warm air mass out of the way. Can bring thunderstorms before and colder temperatures after.

mP

Maritime Polar

What kind of front is shown in this picture?

Cold

Warm air

Rises

Most tornadoes in the world occur in?

The central part of the US, known as Tornado Alley

A Stationary Front forms…

When a warm and cool air mass meet, but neither has the energy to move the other

A Warm Front forms…

When a warm air mass pushes a cold air mass away. Cloudy and long periods of light precipitation.

cT

Continental Tropical air mass

tornado

A rotating column of air with a width of a few yards to more than a mile and spinning at destructively high speeds

Front

The boundary between two air masses

What kind of front is shown in this picture?

Warm

What is the abbreviation for Continental Tropical air mass?

cT

What type of cloud is known for thunderstorms?

Cumulonimbus

cold front

When a rapidly moving cold air mass overtakes a slow-moving warm air mass

Stationary front

Cold and warm air mass meet and stop moving which causes a few days of rain and wind

Name this front:

Occluded

The movement of hot air UP and cold air DOWN is called?

Convections Currents

What kind of front is shown in this picture?

Cold

Warm front

Warm air slides over cold air that is leaving. Brings light rain or snow with mild weather.

The is in the center of a hurricane?

eye

Cold front produces what kind of weather?

violent thunderstorms or heavy snowfall

warm front

When a warm air mass overtakes a cold air mass

What kind of front is in this picture?

Stationary

In which front is cold air pushing warm air out of the way?

Cold front

What does this symbol represent?

Warm front

Thunderstorms occur when…

warm air rises, carrying moisture with it

What is the result of the convection currents in the Earth's atmosphere?

Winds

Cold front

Cold dense air pushes up warm air. Brings violent storms.

occluded front

two cold air masses converge on a warm air mass
