Question 1

Which cloud forms in descending air?

Accepted Answer

Mammatus clouds are associated with descending air, often forming on the underside of the anvil of a cumulonimbus cloud, indicating turbulent air movements and downdrafts.

Question 2

In 1887, Ralph Abercromby and Hugo Hildebrandsson expanded Howard's original cloud classification system and published a classification system that, with only slight modification, is still in use today. In their system, ____ principal cloud forms are divided into ____ primary cloud groups.

Accepted Answer

Ten principal cloud forms are divided into four primary cloud groups in the system developed by Ralph Abercromby and Hugo Hildebrandsson, which expanded on Howard's original cloud classification.

Question 3

Radiation fog typically forms on ____.

Accepted Answer

Radiation fog typically forms on clear, calm nights when the earth's surface cools rapidly, leading to the condensation of water vapor in the air near the surface.

Question 4

Which two clouds can produce precipitation?

Accepted Answer

Cumulonimbus and nimbostratus clouds are known for their ability to produce precipitation. Cumulonimbus clouds are associated with heavy rain, thunderstorms, and severe weather conditions, while nimbostratus clouds are typically linked to continuous rain or snow.

Question 5

The scattering effect of dry haze produces a ____ color when viewed against a dark background and a ____ tint when viewed against a light-colored background.

Accepted Answer

The scattering effect of dry haze scatters shorter (blue) wavelengths of light more efficiently when viewed against a dark background, producing a bluish color. Against a light background, the longer (yellowish) wavelengths are more apparent, resulting in a yellowish tint.

Question 6

In 1803, Luke Howard, an English naturalist, developed a cloud classification system that employed ____ words to describe clouds as they appear to a ground observer.

Accepted Answer

Luke Howard used Latin words to describe clouds, which is why many cloud names are still in Latin today.

Question 7

Suppose two ocean currents with different temperatures are flowing next to one another. If the wind blows perpendicular to the currents, we would expect to find ____.

Accepted Answer

Advection fog forms when moist air passes over a cooler surface and the air cools to its dew point. In this scenario, as the wind blows across the two ocean currents of different temperatures, it would likely lead to the formation of advection fog due to the mixing of air temperatures and moisture levels.

Question 8

The cloud with the greatest vertical growth is ____.

Accepted Answer

Cumulonimbus clouds have the greatest vertical growth, often extending from near the Earth's surface to the stratosphere. They are associated with heavy rain, thunderstorms, and severe weather conditions.

Question 9

Nuclei with a radius of less than 0.1 micrometers are referred to as ____ nuclei.

Accepted Answer

Aitken nuclei are small particles, less than 0.1 micrometers in radius, that serve as nuclei for water droplet formation in the atmosphere.

Question 10

The dew point is the temperature at which ____.

Accepted Answer

The dew point is the temperature at which saturation occurs, meaning the air cannot hold any more water vapor and condensation begins, leading to the formation of dew.

Question 11

Hail is usually associated with ____ clouds.

Accepted Answer

Hail is typically associated with cumulonimbus clouds, which are large, towering clouds often involved in severe weather conditions, including thunderstorms where hail can form.

Question 12

One benefit polar-orbiting satellites offer is that they ____.

Accepted Answer

Polar-orbiting satellites scan from north to south and with the Earth's rotation, they cover an area further west on successive orbits. They can scan clouds directly beneath them, gather sharp images from polar regions, and provide detailed images of clouds and storms, making all the provided options correct benefits of polar-orbiting satellites.

Question 13

Near the shore of an extremely large lake, steam fog is more likely to form during the ____ and advection fog in early ____.

Accepted Answer

The answer of Near the shore of an extremely large...

Question 14

On an ordinary day, a volume of air about the size of your index finger contains between ____ and ____ particles.

Accepted Answer

The correct answer is D because on an ordinary day, a volume of air about the size of your index finger contains between 1,000 and 150,000 particles.

Question 15

In Howard's cloud classification system, sheet-like clouds were named ____ ("layer"), a puffy cloud ____ ("heap"), a wispy cloud ____ ("curl of hair"), and a rain cloud ____ ("violent rain").

Accepted Answer

In Howard's cloud classification system, sheet-like clouds are called "stratus" (meaning "layer"), puffy clouds are called "cumulus" (meaning "heap"), wispy clouds are called "cirrus" (meaning "curl of hair"), and rain clouds are called "nimbus" (meaning "violent rain").

Question 16

As Apollo 12 ascended into the atmosphere, the height of the surrounding clouds was noted to be 42,000 feet. A lightning strike was seen within these clouds, indicating that they must have been ____.

Accepted Answer

Cumulonimbus clouds are known for their association with thunderstorms and lightning, and they can extend to great heights in the atmosphere, often exceeding 20,000 feet. The observation of a lightning strike within clouds at a height of 42,000 feet strongly indicates the presence of cumulonimbus clouds, as they are the type capable of reaching such altitudes and producing severe weather phenomena like lightning.

Question 17

Which region of the United States is particularly prone to advection fog?

Accepted Answer

The Pacific coast is particularly prone to advection fog due to the cold California Current flowing southward along the western coast of North America, cooling the air above it and causing moisture in the air to condense into fog as warmer air is advected over the cooler water.

Question 18

When temperatures are below freezing, the temperature to which air must be cooled in order for a phase change (from liquid to ice)to occur is called the ____.

Accepted Answer

The frost point refers to the temperature to which air must be cooled for frost to form when the temperature is below the freezing point of water. This is a specific type of dew point that occurs at temperatures below freezing, leading to the formation of ice or frost rather than dew.

Question 19

Advection fog is often observed along the Pacific coast during summer, as westerly winds carry moist air toward the shore. The fog forms because the surface water near the coast is ____ the surface water farther offshore.

Accepted Answer

Advection fog forms when warm, moist air moves over a cooler surface, causing the air to cool to its dew point and condense into fog. Along the Pacific coast, the surface water near the coast is much colder than the water farther offshore, often due to upwelling, which brings cold water from the deep ocean to the surface. This temperature difference is what causes advection fog to form.

Question 20

Which region of the United States is particularly prone to upslope fog?

Accepted Answer

The Front Range of the Rocky Mountains is particularly prone to upslope fog due to moist air being forced to rise along the eastern slopes of the Rockies, cooling and condensing to form fog.
