Exam 5: Condensation Dew Fog and Clouds

Wet haze restricts visibility more than dry haze.

A layer of dust or salt particles suspended above a region is called ____________________.

In Ralph Abercromby's and Hugo Hildebrandsson's cloud classification system,each of the four primary cloud groups is identified by the type of precipitation it produces.

Which cloud type is composed of ice crystals and can cause a halo to form around the Sun or Moon?

The fog that forms along the Pacific coastline of North America is mainly of which type?

Which cloud forms in descending air?

What kinds of information about clouds could you hope to determine using infrared and visible satellite photographs?

It is difficult to directly identify significant cloud and surface features on an infrared image when ____ differences are small.

Outline the historic development of the cloud classification system used today.

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.

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

If fog is forming in Denver,Colorado (located on the eastern side of the Rocky Mountains),and the wind is blowing from the east,then the fog is most likely

The foggiest spot near sea level in the United States is Cape Cod,Massachusetts.

An anvil-shaped top is most often associated with

Distinguish among dry haze,wet haze,and fog.

Fog is a major hazard to aviation.

When viewed from the surface,these clouds may be viewed as individual cloud elements (puffs)or as rows of ripples that resemble the scales of a fish.

When surfaces such as twigs,leaves,and blades of grass cool below the saturation temperature,water vapor begins to condense upon them,forming tiny visible specks of water called ____________________.If the air temperature should drop to freezing or below,the ____________________ will freeze,becoming tiny beads of ice called ____________________.

Even at high elevations where cirrus clouds are found,liquid water still exists in the clouds.
