Question 1

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

Accepted Answer

Infrared imagery primarily detects temperature differences between objects, including clouds, the surface, and other atmospheric features. When temperature differences are small, it becomes challenging to distinguish between these features on an infrared image.

Accepted Answer

Noctilucent clouds are best seen during twilight in the summer months at high latitudes, poleward of 50 degrees.

Question 7

When a cloud forms over and extends downwind of an isolated mountain peak, it is called a ____ cloud.

Accepted Answer

Banner clouds form specifically in the lee of isolated mountain peaks, appearing to extend downwind from the peak, resembling a flag or banner. This phenomenon occurs when moist air flows over the mountain, cooling and condensing on the leeward side to form a cloud.

Question 10

Mammatus clouds most frequently form on the underside of ____ clouds.

Accepted Answer

Mammatus clouds are most commonly associated with cumulonimbus clouds, which are large, towering clouds often involved in thunderstorms and severe weather conditions. These pouch-like protrusions form on the underside of the cloud base and are indicative of turbulent weather conditions.

Question 11

Nacreous clouds form in the ____.

Accepted Answer

Nacreous clouds, also known as polar stratospheric clouds, form in the stratosphere at altitudes of 15,000 to 25,000 meters, especially in polar regions and during the winter at high latitudes.

Question 13

This particular technological innovation, launched in 2006, contains a very sensitive radar that uses microwave radiation to peer into a cloud and unveil its fine structures, including the altitude of its top and base, its thickness, optical properties, the abundance of liquid and ice particles, along with the intensity of precipitation within the cloud.

Accepted Answer

CloudSat, launched in 2006, is equipped with a cloud-profiling radar that uses microwave radiation to provide detailed observations of cloud structure and properties, including their vertical dimensions, precipitation intensity, and the distribution of liquid and ice.

Question 14

Snow covering the ground is an especially favorable condition for the formation of precipitation fog, also known as _____________ fog.

Accepted Answer

The answer of Snow covering the ground is an especially...

Question 20

To a weather forecaster a clear sky is one where no clouds are present. When there are between ____ and ____ clouds covering the sky, there are a few clouds present.

Accepted Answer

A clear sky is defined as having no clouds, and "a few clouds" typically refers to a sky coverage of one-eighth to two-eighths. This is based on the okta system, which divides the sky into eighths to estimate cloud cover.
