Weather and Climate

Reflection of light in all directions

Clouds that form in flat layers and often cover much of the sky

The lower part of the thermosphere

bands of high-speed winds about 10 kilometers above Earth's surface

Electromagnetic waves with wavelengths that are shorter than visible light but longer than X-rays

The transition of a substance directly from the solid to the gas phase without passing through an intermediate liquid phase

The amount of water vapor in a given volume of air

The total energy of motion in particles of a substance

The flow of air from land to a body of water

The pressure caused by the wieght of a column of air pushing down on an area

The third layer of the Earth's atmosphere

An instument used to measure wind speed

The percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature

The change that Earth's rotation causes in the motion of objects and that explains how winds curve

A measure of cooling combining temperature and wind speed

An instrument used to measure relative humidity

An instrument used to measure changes in air pressure

Winds that blow steadily from specific directions over long distances

The outermost layer of Earth's atmosphere

Wispy, feathery clouds made of ice crystals that form at high levels

Fluffy, white clouds, usually with flat bottoms that look like rounded piles of cotton

The outer layer of the thermosphere

Winds that blow over short distances

The second-lowest layer of Earth's atmosphere

The lowest layer of the Earth's atmosphere

Electromagnetic waves with wavelengths that are longer than visible light but shorter than microwaves

The flow of cooler air from over an ocean or lake toward land

A form of oxygen that has three oxygen atoms in each molecule instead of the usual two

A huge body of air that has similar temperature, humidity, and air pressure at any given height

Permanently frozen soil found in the tundra climate region

A polar climate region, with short, cool summers and bitterly cold winters

The climate of coastal regions, with relatively warm winters and cool summers

An instrument used to measure precipitation

The areas near both poles, from about 66.5 to 90 south latitudes

The areas between the tropical and polar zones

A high pressure of dry air

A "dome" of water that sweeps across the coast where a hurricane lands

A line on a weather map that joins places that have the same temperature

A droplet of water that measures 0.05-0.5

The word added to a cloud name to describe that the cloud is at a height between 2 and 6 kilometers. Means "high"

Cut off, as in front where a warm air mass is caught between two cooler air masses

A humid air mass that forms over oceans

The side of a mountain range that faces the oncoming wind

A line on a weather map that joins places that have the air pressure

The climate of the centers of continents, with cold winters and warm or hot summers

Water droplets that freeze as they hit cold surfaces

The boundary where unlike air masses meet but do not mix

Ice pellets 5 millimeters or less

Ice pellets 5 millimeters or more

A swirling center of low air pressure

Climate conditions within a small area that differ from those in the surrounding area

the average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area

The area near the equator, between about 23.5 north latitude and 23.5 south latitude

The side of a mountain range that faces away from the oncoming wind

The word added to a cloud name to describe that the cloud produces precipitation. Means "rain"

A dry air mass that forms over land

A droplet of water that measures 0.005-0.5
