Severe storms
100
This is the study of atmospheric phenomenon
What is meterology
100
This effect, along with the heat imbalance on Earth, creates the three major global wind systems
What is the Coriolis effect
100

The root word means sea, usually involving something over the water

What is maritime?

100
This is a narrow region separating two air masses of different densities
What is a front
100

Forms under this pressure system and have winds exceeding 74 MPH

Hurricane

200
This is the current state of the atmosphere
What is weather
200

A moving warm air mass collides with a slowly moving cold air mass and the warm air moves over the cold air.

What is a warm front?

200

The word means over land

What is continental?

200

When a rapidly moving cold air mass runs into a slowly moving warm air mass; the denser cold air slides under the lighter warm air.

What is a cold front?

200

Usually more frequent in the warmer seasons of Spring and Summer, forming in low pressure systems, and over land.

Tornado

300
This is the term for long-term variations in weather for a particular area
What is climate
300

When cold and warm air masses meet, but neither one has enough force to move the other.

What is a stationary front?

300

This air mass comes from either the north or south poles.

What is polar?

300

A region where the atmospheric pressure at the surface of the planet is greater than its surrounding environment

High Pressure

300

Warm, moist air over the ocean

What is the energy source for a hurricane?

400
This term refers to a large body of air that takes on the characteristics of the area over which it forms
What is an air mass
400

Where precipitation falls outside of a funnel cloud?

What is downdraft?

400

of, being, or characteristic of a region or climate that is frost-free with temperatures high enough to support year-round plant growth given sufficient moisture. This means coming from the equator

What is Tropical?

400

In surface low-pressure systems, the air does this

What is rise

400

Higher precipitation with cloudy, overcast skies, indicating incoming unstable weather.

What is low pressure?

500

The result of the weight of a column of air pushing down on an area.

What is an air pressure?

500
These are narrow bands of fast, high-altitude, westerly winds
What is the jet stream
500

When warm air slowly covers over cold air which produces steady light rain and pleasant temperatures.

What is a warm front?

500

Global wind systems flow on either side of the equator in what direction?

Counterclockwise in Northern hemisphere and clockwise in the Southern hemisphere

500

storm --- usually, but not necessarily, thunderstorm --- that contain updrafts that rotate about a vertical axis

What is a supercell?
