100

Gray; layered clouds that cover the lower part of the sky. Sometimes called fog.

What are stratus clouds?

100

When rising warm air lifts air off the ground and begins to condense higher up in the atmosphere. This often begins cloudy weather with precipitation near a front. These rotate counterclockwise.

What is a low pressure (or a cyclone, shown with a red L on a weather map)?

100

Region of the electromagnetic spectrum that we can see.

What is visible light or ROYGBIV?

100

3 things that often happen either at or near a weather front.

What are condensation, clouds, precipitation, winds, etc. (3 of them)?

100

A prevailing wind from 30° to 60° latitude that deflects air masses.

What are the westerly winds?

200
White, puffy clouds that look like piles of cotton; they are known as fair-weather clouds
What are cumulus clouds?
200

Forms in the tropics with warm, wet air and lower pressure.

What is tropical maritime?

200

Thankfully some ultraviolet radiation is absorbed by this.

What is the ozone layer?

200

Scientists who study weather

Who are meteorologists?

200

Near a large body of water, 1) the wind pattern during the day and 2) the wind pattern at night.

What is 1) a sea breeze and 2) a land breeze?

300
Thin, feathery clouds that appear high in the sky; they are a sign that rain or snow is on the way
What are cirrus clouds?
300

Forms a cold dry air mass.

What is continental polar?

300

Dust-sized particles and gases in the atmosphere disperse light in all directions.

What is scattering?

300

When a cold air mass overtakes a warm air mass. Shown by a blue line with blue triangles pointing in the direction the cold air is moving.

What is a cold front?

300

The effect that makes ocean currents and winds turn as they move across the Earth's surface and that is due to the Earth's rotation.

What is the Coriolis Effect?

400

You can expect poor weather with relatively warmer temperatures when this is in the area.

What is a low pressure system?

400
Large, powerful storm that occurs over large bodies of water
What is a hurricane?
400

What convection causes that distributes the sun's heat more evenly across the Earth.

What is wind?

400

When a warm air mass overtakes a cold air mass. Show on a weather map by a red line with red half-circles showing the direction of movement of the warm air.

What is a warm front?

400

Two categories of prevailing winds on earth.

What are local and global wind patterns?

500

A convection updraft causes these clouds to rise up very high into the atmosphere, making them the tallest clouds. They contain much energy, and are the producers of thunderstorms.

What are cumulonimbus clouds?

500

When cooler air sinks, pressing on the ground and sweeping away cloudy, rainy weather. It is usually a precursor to nice, sunny days ahead. These rotate clockwise.

What is a high pressure system (or an anticyclone, shown by a blue H on a weather map).

500
Type of electromagnetic radiation that causes the earth to heat up.

What is infrared radiation?

500

When a cold front overtakes a warm front, trapping warm air in between two cold air masses. Often happens in snow storms in the Northern U.S. Shown in purple on weather maps, with alternating purple triangles and half-circles on the same side of the purple line.

What is an occluded front?

500

Instruments that show wind direction and speed

What is a wind vane and anemometer?
